C Structure

Example

#include <stdio.h>

int main() {
  printf("Welcome to C Tutorial");
  return 0;
}

#include <stdio.h> - It's an header file, which has all the necessary information to include the input/output related functions in our program.
Example: printf, scanf etc.
int main() - The main function is the starting point of program execution. We can declared it with integer or void.
printf("Welcome to C Tutorial"); - Prints the value iven in the printf() function.
return 0; - The calling function will expect an integer value from the main function as it is declared the function main() with integer.

Note: Always keep semicolon " ; " at the end of each line.

Environment Setup

Install C IDE on your PC and start running your own code.
Here are some applications and software used to install IDE

After deploying c in your pc, create a new file with .c extension and start your c program.
