Question

1. Create a function template that takes a number as an argument and returns the absolute value. The absolute value of a number is the number without the sign, such that the absolute value of -5 is 5 and the absolute value of +5.0 is 5.0. Test your function with at least two numeric data types.

Answer 1

#include <iostream>

using namespace std;

template<class T>
T absolute(T data) {
    if (data < 0)
        return -1 * data;
    else
        return data;
}

int main() {
    // testing with double
    cout << absolute(2.9) << endl;
    cout << absolute(-5.6) << endl;

    // testing with int
    cout << absolute(-9) << endl;
    cout << absolute(11) << endl;
    return 0;
}
