How is Utility function "abs()" used in C++?
How to find the absolute value of a given number?
|
|
Explanation |
|
abs() is a Utility Function that returns the absolute value for the given number.
For long, double values the function returns the same results as "labs()", "fabs()".
Syntax to find Absolute Value:
int abs(int num);
long abs (long num);
double abs(double num);
Example:
#include <stdlib.h>
#include <stdio.h>
int main ()
{
int a,b,c,d;
a=45;
b=abs(a);
c=-15;
d=abs(c);
printf ("The absolute value of %d is:: %d\n",a,b);
printf ("The absolute value of %d is:: %d\n",c,d);
return 0;
}
|
Result:
The absolute value of 45 is:: 45
The absolute value of -15 is:: 15
Abnormal program termination
In the above example abs() is used to find the absolute value of integers "45","-15".
