Absolute or abs() function in c programming. The abs () function returns the absolute value of the given integers and is defined in the stdlib. h header file. So, in order to return the absolute value of a given number, the C program must include the stdlib.h header file. Only positive numbers are returned by the abs() function.

#include <stdio.h>

#include <stdlib.h>

int main()

{

int a = abs(100);

int b = abs(-500);

printf("Absolute or abs number of a = %d\n",a);

printf("Absolute or abs number of b = %d",b);

return 0;

}

Output:

Absolute or abs number of a = 100

Absolute or abs number of b = 500

## What is function in c programming absolute or abs()

The abs function returns an integer’s absolute value in the C programming language. The absolute value of an integer is returned by the abs( ) function in C. Every number has a positive absolute value. In C, you can only use integer values. An example of asset-based security is a collateralized debt obligation. It’s similar to a loan or bond in that it’s backed by a portfolio of debt instruments, such as bank loans, mortgages, credit card receivables, airplane leases, smaller bonds, and occasionally even other ABSs or CDOs.

## Uses of abs function in c

The abs() method is used to return a number’s absolute value. Only one input is required for abs(): an integer whose absolute value is to be returned. An integer, a floating-point number, or a complex number can be used as the parameter.

## Standard library function in c and its uses

String handling, mathematical computations, input/output processing, memory management, and a variety of other operating system services are all covered by the C standard library, which includes macros, type definitions, and functions.

h is the header of the C programming language’s general-purpose standard library, which includes functions for memory allocation, process control, conversions, and more. It is compatible with C++ and is referred to as c stdlib in that language. “Stdlib” is an acronym for “standard library.”
