find the average of an array c++ code example
Example: cpp program to find average of n numbers
#include <iostream>
using namespace std;
int main() {
// initialize an array without specifying size
double numbers[] = {7, 5, 6, 12, 35, 27};
double sum = 0;
double count = 0;
double average;
cout << "The numbers are: ";
// print array elements
// use of range-based for loop
for (const double &n : numbers) {
cout << n << " ";
// calculate the sum
sum += n;
// count the no. of array elements
++count;
}
// print the sum
cout << "\nTheir Sum = " << sum << endl;
// find the average
average = sum / count;
cout << "Their Average = " << average << endl;
return 0;
}
