How is the absolute value represented in the C language?

In C language, you can use the abs() function to calculate the absolute value of a number. This function is defined in the stdlib.h header file and can be called directly. Here is an example code:

#include <stdio.h>
#include <stdlib.h>

int main() {
    int num = -10;
    int abs_num = abs(num);

    printf("The absolute value of %d is %d\n", num, abs_num);

    return 0;
}

The output is:

The absolute value of -10 is 10
