How is the output of text displayed on the screen in a C program?

In a C program, the output of text is typically displayed on the screen using the printf() function, which is part of the Standard Input Output library (stdio.h).

Example of Displaying Output:

Here’s a simple example of how to use printf() to display text on the screen:

#include <stdio.h>

int main() {
    printf("Hello, World!\n"); // Displaying text on the screen
    return 0;
}

Explanation:

#include <stdio.h>: This line includes the Standard Input Output library, which contains the declaration for the printf() function.
int main(): This is the main function where the execution of the program begins.
printf("Hello, World!\n");: This line calls the printf() function to print the string "Hello, World!" to the screen. The \n is a newline character that moves the cursor to the next line after printing.
return 0;: This indicates that the program has executed successfully.

When you run this program, the output will be displayed on the terminal as:

Hello, World!

This is how text output is typically displayed in a C program.
