You are to find all the absolute value functions you can and rewrite all of them

Question

You are to find all the absolute value functions you can and rewrite all of them overloading the abs function name. At a minimum, you should have the int, long, float, and double types represented.

Variables:

Declare four variables of type int, double, float, long and initialize them to some random values:

int i = -4;

double d = 7.5;

Functions:

Call your functions Abs( )

From main, call the four overloaded functions with these variables.

In each function, place a debug statement to print out which function is being called. For example:

cout<<"Abs(int) is being called"<<endl;

Place appropriate cout functions in main to let the user know what is being called, how it's being called and what the result it.

Explanation / Answer

#include<iostream>

using namespace std;

int abs(int n)

{

    cout<<"Abs(int) is being called : ";

    // if n is negative

    if( n < 0 )

        return -n;

    else

        return n;

}

double abs(double n)

{

    cout<<"Abs(double) is being called : ";

    // if n is negative

    if( n < 0 )

        return -n;

    else

        return n;

}

float abs(float n)

{

    cout<<"Abs(float) is being called : ";

    // if n is negative

    if( n < 0 )

        return -n;

    else

        return n;

}

long abs(long n)

{

    cout<<"Abs(long ) is being called : ";

    // if n is negative

    if( n < 0 )

        return -n;

    else

        return n;

}

int main()

{

    int a = -3;

    float b = -3.25;

    double c = -4.56;

    long d = 2;

    cout<<abs(a)<<endl;

    cout<<abs(b)<<endl;

    cout<<abs(c)<<endl;

    cout<<abs(d)<<endl;

    return 0;

}
