c program boilerplate code
Here is a basic boilerplate code for a C program, along with explanations for each step:
#include <stdio.h>
int main() {
// Code goes here
return 0;
}
Include the necessary header file
The first line #include <stdio.h>
is a preprocessor directive that includes the standard input/output library header file. This file contains functions like printf
and scanf
that allow you to interact with the user through the console.
Define the main function
The int main()
function is the entry point of a C program. It is where the program execution starts. In this example, the main
function is defined without any parameters.
Write your code
Between the opening and closing braces {}
of the main
function, you can write your program logic. This is where you would define variables, perform calculations, and call other functions to achieve the desired functionality.
Return statement
The return 0;
statement is used to exit the main
function. In C, returning 0 from the main
function indicates that the program has executed successfully. You can also return a non-zero value to indicate an error or abnormal termination.
