C programming examples with output

C programs with output showing usage of operators, loops, functions, arrays, performing operations on strings, files, pointers. Download executable files and execute them without compiling the source file. Code::Blocks IDE is used to write programs; most of these will work with GCC and Dev C compilers. The first program, prints 'Hello World.' The free C/C and Fortran IDE. Code::Blocks is a free C/C and Fortran IDE built to meet the most demanding needs of its users. It is designed to be very extensible and fully configurable. Built around a plugin framework, Code::Blocks can be extended with plugins. Any kind of functionality can be added by installing/coding a plugin.

Example 1 - C hello world program
/** My first C program */

Output of program:
'Hello World'

Example 2 - C program to get input from a user using scanf

int main()
{
int x;

printf('Input an integern');
scanf('%d',&x);// %d is used for an integer

printf('The integer is: %dn', x);

return0;
}

Output:
Input an integer
7897
The integer is: 7897

Example 3 - using if else control instructions

int main()
{
int n;

printf('Enter a numbern');
scanf('%d',&n);

if(n >0)
printf('Greater than zero.n');
else
printf('Less than or equal to zero.n');

return0;
}

Output:
Enter a number
-45
Less than or equal to zero.

Example 4 - while loop example

Output:
1 2 3 4 5 6 7 8 9 10

Example 5 - C program check if an integer is prime or not

Example 6 - command line arguments

int main(int argc,char*argv[])
{
int c;

printf('Number of command line arguments passed: %dn', argc);

for(c =0; c < argc; c++)
printf('%d argument is %sn', c +1, argv[c]);

return0;
}

This program prints the number of arguments and their contents.

How to compile C programs with GCC compiler?

If you are using GCC on Linux operating system, then you may need to modify the programs. For example, consider the following program that prints the first ten natural numbers.

int main()
{
int c;

for(c =1; c <=10; c++)
printf('%dn', c);
getch();
return0;
}

The program includes a header file <conio.h> and calls the getch function, but this file is Borland specific, so it works in Turbo C compiler but not in GCC. The program for GCC must be like:

int main()
{
int c;

/* for loop */

for(c =1; c <=10; c++)
printf('%dn', c);
return0;
}

If you are using GCC, save the program in a file say 'numbers.c' to compile the program, open the terminal and enter the command 'gcc numbers.c', this compile the program and to execute it enter the command './a.out' do not use quotes while executing commands. You can specify the output file name as 'gcc numbers.c -o numbers.out', to run execute './numbers.out' in the terminal.

C programming tutorial

A program consists of functions that contain instructions given to a machine to perform a task. The process of writing it includes designing an algorithm, drawing a flowchart, and then writing code. After writing it, you need to test it and debug it if it does not produce the required output.

To write a program, you need a text editor (use your favorite one) and a compiler. A compiler converts source code into machine code, which consists of zero's and one's only, ready to be executed on a machine.

An IDE (Integrated Development Environment) provides a text editor, compiler, debugger, etc. for developing programs and managing projects. Code::Blocks IDE provides an ideal environment for development. It can import Microsoft Visual C++ projects, is extendable as it uses plug-ins, open-source, and cross-platform.

How to write a C program?

A program must have at least a main function. A function consists of declarations and statements. A statement is an expression followed by a semicolon. For example, a + b, printf('C program examples') are expressions and a + b; and printf('C is an easy to learn computer programming language'); are statements.

To use a variable, we must indicate its type, whether it is an integer, float, character, or others. C language has many built-in data types, and we can create ours using structures and unions. Every data type has its size that may depend on the machine; for example, an integer may be of 2 or 4 Bytes. Data is stored in a binary form, i.e., a group of bits where each bit can be '0' or '1'.

Keywords such as 'switch,' 'case,' 'default,' 'register,' are reserved words with predefined meaning and can't be used as the name of a variable or a function. Memory can be allocated at compile-time or run-time using malloc and calloc functions. C language has many features such as recursion, preprocessor, conditional compilation, portability, pointers, multi-threading by using external libraries, dynamic memory allocation. Thanks to these, it is used for making portable software programs and applications. Using networking API's users can communicate and interact with each other and share files.

C standard library contains functions for mathematical operations, characters, input/output, files, and many more. The process of writing a program known as coding requires knowledge of programming language and logic to achieve the desired output. So you should learn C programming basics and start making programs.

Learning data structures (stacks, queues, linked lists, binary trees, graphs) using C provides you a greater understanding as you study everything in detail. A general belief is to go for high-level languages. However, it's a good idea to learn C before learning C++ or Java. C++ is object-oriented and contains all features of C, so learning C help you learn C++ quickly, then you can study Java.

CLion takes a lot of the toil out of C++, allowing me to concentrate on the interesting part: problem solving.

CLion takes a lot of the toil out of C++, allowing me to concentrate on the interesting part: problem solving.

A power tool
for a power language

Who wouldn’t like to code at the speed of thought while the IDE does all the mundane development tasks for them? But is that really possible for a tricky language like C++, what with its modern standards and heavily templated libraries? Why, yes, yes it is! See it to believe it.

Smart C and C++ editor

Code assistance

Read and write code effectively with an editor that deeply understands C and C++. Have completion results filtered by type in Smart Completion. Use Breadcrumbs to track your location inside the hierarchy of scopes. Gain insight into function calls thanks to parameter name hints. Find the context usages of a symbol or simply jump to it by typing its name. CLion will even make sure your code conforms to coding guidelines, including formatting, naming, and more.

Code generation

Generate tons of boilerplate code instantly. Override and implement functions with simple shortcuts. Generate constructors and destructors, getters and setters, and equality, relational, and stream output operators. Wrap a block of code with a statement, or generate a declaration from a usage. Create custom live templates to reuse typical code blocks across your code base to save time and maintain a consistent style.

Safe refactoring

Dev C++ 5.11

Rename symbols; inline a function, variable, or macro; move members through the hierarchy; change function signatures; and extract functions, variables, parameters, or a typedef. Whichever automated refactoring you use, rest assured CLion will safely propagate the appropriate changes throughout your code.

Quick Documentation

Dev C++ Linux

Inspect the code under the caret to learn just about anything: function signature details, review comments, preview Doxygen-style documentation, check out the inferred type for symbols lacking explicit types, and even see properly formatted final macro replacements.

Code analysis on the fly

Create code that's beautiful and correct. With CLion, potential code issues are detected instantly, as you type...

...and can be fixed at the touch of a button, while the IDE correctly handles the changes.

CLion runs its code analysis, Data Flow Analysis, other Clangd-based checks, and Clang-Tidy to detect unused and unreachable code, dangling pointers, missing type casts, no matching function overload, and many other issues.

Integrated debugger

Investigate and solve problems with ease in CLion's friendly debugger, with GDB or LLDB available as the backend.

Attach to local processes or debug remotely. For embedded development, rely on OpenOCD and Embedded GDB Server configurations to do on-chip debugging with CLion.

Dive deeper with disassembly and memory views, and peripheral view for embedded devices.

Set breakpoints

Use line, symbol, exception, and conditional breakpoints to inspect your code’s execution. Log the events, remove breakpoints once hit, or disable them until another one is hit. All of this can be configured in a dedicated dialog.

Evaluate expressions

Make use of the Watches and the Variables views, or evaluate the result of a function call or some complicated expression when stopping at some execution point.

View values inline

Get a full view of your project with variables’ values shown right in the editor as you debug – with no need to switch to the Variables tab in the Debug tool window!

Fully Integrated C/C++ Development Environment

Project models

CLion uses the project model to inform its coding assistance, refactoring, coding style consistency, and other smart actions in the editor. Supported formats include CMake, Makefile, Gradle, and compilation database.

Keyboard-centric approach

To help you focus on code and raise your productivity, CLion has handy keyboard shortcuts for nearly all its features, actions, and commands.

Vim fans are welcome to install the Vim-emulation plugin.

Local and remote work

With an embedded terminal, run any command without leaving the IDE, locally or remotely using the SSH protocol.

After editing your code locally, build, run, or debug your application or unit tests locally, remotely, or on a chip.

Everything you need in one place

CLion includes all the essentials of everyday development: VCS (SVN, Git, GitHub, Mercurial, Perforce), Google Test, Catch and Boost.Test frameworks for unit testing, Doxygen, Database tools, and Markdown support.

What’s New in CLion 2021.2

Updates for CMake and Makefiles

For CMake users, CLion 2021.2 automatically detects and imports CMake Build Presets. For Makefile users, it recognizes GNU Autotools projects, automatically executes preconfiguration steps, and loads projects.

Debugger enhancements

CLion 2021.2 introduces Relaxed breakpoints and brings breakpoints to the disassembly view. LLDB remote debugging is now supported. And Windows users can benefit from enhanced Natvis support and support for minidumps.

Memory safety as you type

Diagnose common cases of dangling pointers and escaping from a local scope by using CLion's static analysis. Optionally, use GSL annotations to mark the code and make local analysis more accurate.

What our customers say

'CLion has been indispensable for me when refactoring large codebases. The refactoring tools and the real-time feedback in the IDE about which lines still need to be updated are excellent time savers. Each release gets better and more responsive than the last!'
