Program for Calculating the Absolute Value of a User-Input Number

To create a program that calculates the absolute value of a number entered by the user, you can use the following code in C:

#include 
#include

int main(void) {
    int num;
    printf("Enter a number: ");
    scanf("%d", &num);
    printf("The absolute value of the number is: %d\n", abs(num));
    return 0;
}

This program prompts the user to enter a number, then calculates and displays its absolute value.

Note: The `abs()` function is used to calculate the absolute value of a number in C.

Explanation of the Code

1. The `#include ` and `#include ` lines are used to include the standard input/output and math libraries, respectively. 2. The `int main(void)` function is the entry point of the program. 3. Inside the `main` function, the user is prompted to enter a number using `printf` and `scanf`. 4. The absolute value of the entered number is calculated using the `abs()` function from the `math.h` library. 5. The result is then printed to the console using `printf`.

This code demonstrates a simple program to calculate the absolute value of a user-input number in C.
