A Simple program finding the absolute value of an integer
A Simple program without using functions
This program find the absolute value of an integer without using a function
#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;
}
