C Tutorial – Examples Of C Programming

It is simple to learn C programming if you follow the tutorials in the correct order and practice C programs along the way. This C tutorial is intended for beginners, so you will have no trouble even if you have no prior knowledge of the C language.
C is a programming language for general-purpose computers. A general purpose language is one that is widely used in many domains and is not domain specific. Dennis Ritchie created the C programming language in 1972 at AT&T Bell Laboratories in the United States.

The Basics of C

Because of the features it provides, C is a very popular programming language. Here are some of the characteristics of the C programming language.
1. Simple
The C programming language is simple and easy to learn.
2. Portable
C is a machine-independent programming language, which means that a C program written on one machine can run on another without requiring any code changes.
3. Fast
C is a compiler-based language that supports only useful features, making C file compilation quick.
4. Extensible
C programs allow for code modifications and the addition of new code to existing programs, making the C language extensible. It becomes easier to add new features to existing C programs.
5. Language for intermediate programmers
C language offers the advantages of both high-level and low-level languages. C, like low-level languages, allows hardware manipulation while also providing high-level user functionality.

A straightforward C program

#include <stdio.h>
int main() {
  printf("Hello World!");
  return 0;
}

Output:

Hello World!

C Array Tutorials

  • Arrays – The fundamentals of arrays.
  • How to implement and use a 2D array in a program.
  • Array Pointer
  • Passing an array to a function – Discover how to pass an array as an argument to a function.

Strings in C

  • C Strings and String Functions – Everything you need to know about strings and string functions. A comprehensive guide.
  • strcat C ()
  • strncat C ()
  • strchr C ()
  • strcmp C ()

  • The letter C strrchr ()
  • strspn C ()
  • strstr C strstr ()
  • strcspn C strcspn ()
  • strlen C ()

Functions written in C

  • C functions – What are functions and how do you use them in a program?
  • Function Call by Value Method – The actual arguments are copied to the formal arguments in the call by value method, so any function operation on arguments has no effect on the actual parameters.
  • Function Call by Reference method – Unlike call by value, this method passes the address of the actual arguments (or parameters) to the formal parameters, which means that any operation performed on the formal parameters affects the value of the actual parameters.

Structure
