C++ Program Calculate Average of Numbers Using Array

C++ Program Find Average of Numbers Using Array

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

#include <iostream> using namespace std; int main() { int n, i; float num[100], sum=0.0, average; cout << "Enter the numbers of data: "; cin >> n; while (n > 100 || n <= 0) { cout << "Error! number should in range of (1 to 100)." << endl; cout << "Enter the number again: "; cin >> n; } for(i = 0; i < n; ++i) { cout << i + 1 << ". Enter number: "; cin >> num[i]; sum += num[i]; } average = sum / n; cout << "Average = " << average; return 0; }

Enter the numbers of data: 6

1. Enter number: 45.3
2. Enter number: 67.5
3. Enter number: -45.6
4. Enter number: 20.34
5. Enter number: 33
6. Enter number: 45.6

Average = 27.69
