Can you rewrite function double cal_average()differently (use different coding to write it, but the resultremain the same) C++
#include <iostream>#include <iomanip>using namespace std;
void format_fun(){ cout<<setw(30)<<setfill('-')<<""<<endl;}
void populate_arr(int narr [], int asz){format_fun();cout << "CS 162 Assignment One" << endl <<endl;format_fun(); for (int i = 0; i < asz; i++){ cout << "Enter number: "; cin >> narr; format_fun(); }}
double cal_average(int narr [], int asz){ double sum = 0; for (int i = 0; i < asz; i++){ sum += narr; } return sum / asz;}
void print(int narr [], int asz, double average){cout << "Array value = ";for (int i = 0; i < asz; i++){ cout << narr << " ";}cout << endl;format_fun();cout << fixed << setprecision(2);cout << "Average = " << average << endl;}
int main(){ const int arr_sz = 3; int arr_values [arr_sz];
populate_arr(arr_values,arr_sz); double average = cal_average(arr_values, arr_sz); print(arr_values,arr_sz, average);
format_fun(); return 0;}
Sample output
--------------------------------
CS 162 Assignment One
--------------------------------
Enter number: 23
--------------------------------
Enter number: 44
--------------------------------
Enter number: 55
--------------------------------
Array values = 23 44 55
--------------------------------
Average = 40.67
--------------------------------
