Syntax 

     #include <stdlib.h>
     int abs (int x);

Return Values 

x             The absolute value of the integer specified in x.

Example 

The following program calculates integer absolute values until a zero is
entered from the keyboard:

     #include <stdlib.h>
     #include <stdio.h>
     main(void)
     {
     int value;
     do
       {
       printf("Enter value: ");
       scanf("%d", &value);
       if (value == 0)
          exit (0);
       printf("Absolute value of %d is %d.\n", value, abs(value));
       }
       while (value !=0);
     }
