Question

C++ help Please.

Complete this function that calculates the N-powers of the numbers in an array "numbers" and put the results in the same numbers array. N is given as the exponent parameter. Function returns the sum of all the results. Assume that "cmath" is already included. Use only one loop in the function   

In main()

This is given to you as a sample, do not write it:

double arr [5] = { 1.2, 3.4 , 5.6, 12.8, 1.7 };

double result = getPowers(arr, 3, 5); // result contains the sum of the result

array

// arr array will contain the cubic powers (power 3) of the numbers

Function definition:

double getPowers(double numbers[ ], int exponent, int size) {

//……………….

}

Explanation / Answer

#include<iostream>
#include<cmath>

using namespace std;
double getPowers(double numbers[ ], int exponent, int size) {
double sum = 0;
for(int i=0; i<size; i++) {
sum = sum + pow(numbers[i], exponent);
}
return sum;
}
int main(){
double arr [5] = { 1.2, 3.4 , 5.6, 12.8, 1.7 };
double result = getPowers(arr, 3, 5);
cout<<"Result: "<<result<<endl;
}

Output:

sh-4.2$ g++ -o main *.cpp                                                                                                                                                                                                                                              

sh-4.2$ main
