Construct an overloaded function equivalent to the pow(x, n), where x can be either integer or float and n is an integer.
Aug 31, 2018For this question, there will be two argument function. The function is overloaded based on the type of arguments, and is float and integer.
Program:
#include<iostream>
using namespace std;
// do not include cmath header for this
//program as it may conflict
// declarations of overloaded functions
int pow(int x, int n);
float pow(float x, int n);
int main(){
int a = 10;
float b = 20.5;
int index = 5;
cout<<"pow("<<a<<", "<<index<<") = "<<pow(a, index)<<endl;
cout<<"pow("<<b<<", "<<index<<") = "<<pow(b, index)<<endl;
return 0;
}
// function defination
int pow(int x, int n){
// using simple mechanism for repeated multiplication
int product = x;
for(int i = 0; i < n - 1; i++){
product *= x;
}
return product;
}
float pow(float x, int n){
float product = x;
for(int i = 0; i < n - 1; i++){
product *= x;
}
return product;
}
Sample Run:
pow(10, 5) = 100000 pow(20.5, 5) = 3.62051e+06
