stdio

Sure! I'll provide a response without any personal words or sentences.

In C programming language, stdio is a standard input/output library. It provides functions for input and output operations, such as reading from and writing to files, printing to the console, and more.

To use stdio functions in your C program, you need to include the stdio.h header file at the beginning of your code. This file contains the declarations of the standard input/output functions and constants.

Here is an example of how to include the stdio.h header file in your C program:

#include <stdio.h>

Once you have included the stdio.h header file, you can use the functions provided by stdio. For example, you can use the printf function to print output to the console, and the scanf function to read input from the user.

Here is an example of how to use the printf and scanf functions:

#include <stdio.h>

int main() {
    int num;

    printf("Enter a number: ");
    scanf("%d", &num);

    printf("The number you entered is: %d\n", num);

    return 0;
}

In this example, the program prompts the user to enter a number, reads the input using scanf, and then prints the entered number using printf.

I hope this helps! Let me know if you have any further questions.
