[CPP]
#include <iostream>
using namespace std;

int main()
{
int number;
int abs_number;

// Ask for input
cout << "This program finds the absolute value of an integer." << endl;
cout << "Enter an integer (positive or negative): ";
cin >> number;

// Find the absolute value
if(number >= 0)
{
abs_number = number;
}
else
abs_number = -number;

// Print out output
cout << "The absolute value of " << number << " is " << abs_number;
cout << endl;
return 0;
}

The same program using function

This program finds the absolute value of an integer using a function

int Abs(int i); // Function prototype
int main()
{
int number;
int abs_number;

cout << "This program finds the absolute value of an integer." << endl;
cout << "Enter an integer (positive or negative): ";
cin >> number;

// Calling the function Abs()
abs_number = Abs(number);
cout << "The absolute value of " << number << " is " << abs_number;
cout << endl;
return 0;
}
// Function definition
int Abs(int i)
{
if( i >= 0)
return i;
else
return -i;
}[/CPP]
