Write a C++ code to overload the function sqr() . In the first call of the function sqr(), an integer 15 is passed. The compiler executes the integer version of the function and returns result 225. In the second call a float value 2.5 is passed to function sqr(). The compiler executes the float value of the function and returns the result 6.25. The selection of which function to execute is decided at the run time by the compiler according to the datatype of variable passed.

    return x*x;
}


int main() {
    cout << "Square of 15 is " << sqr(15) << endl;
    cout << "Square of 2.5 is " << sqr(2.5f) << endl;
}
