abs Arithmetic function in C programming language

We will learn about abs Arithmetic function in C programming language

In the C Programming Language, the abs() Arithmetic function returns the absolute value of an integer. The absolute value of a number is always positive.

abs Arithmetic function

Declaration

Syntax

The syntax of the abs() function in the C programming Language

int abs(int x);

parameters or Argument

x is the parameter or argument of this function.

Return value

When a value for x is passed, this function returns the absolute value of x

Required Header

In the C Language, the required header file for abs() function is

#include <stdlib.h>

Example

Program 1

The following example explains the usage of abs() function

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

int main()
{
    int a=10,b=-12;
    printf("the absolute value of a: %d\n",abs(a));
    printf("the absolute value of b: %d\n",abs(b));
    getch();
    return 0;
}

When the above program is compiled and run, it will produce the following result

the absolute value of a: 10

the absolute value of b:12

Program 2

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int m,n,o,p;//diclare of local  variable
    printf("Enter the positive number\n");
    //get input positive
    scanf("%d",&n);
    printf("Enter the Negative number\n");
    //get input negative
    scanf("%d",&o);
    m=abs(n);//assign absolute value of n to m
    p=abs(o);//assign absolute value of o to p
    printf("absolute value of the positive value is: %d\n",m);
    printf("absolute value of the Negative value is: %d",p);
    getch();
    return 0;
}

When the above program is compiled and run, it will produce the following result

Enter the positive number

Enter the Negative number

-76

the absolute value of the positive value is: 56

the absolute value of the Negative value is: 78
