Find array elements that are greater than average
Given an array of numbers, print all those elements that are greater than average.
Examples:
Input : 5, 4, 6, 9, 10 Output : 9 10 Explanation: avg = 5 + 4 + 6 + 9 + 10 / 5; avg = 34 / 5 avg = 6.8 Elements greater than 6.8 are 9 and 10 Input : 1, 2, 4, 0, 5 Output : 4 5
1) Find average of elements.
2) Traverse array again and print elements that are greater than average,
C++
// A C++ program to print elements which are // greater than avg of array #include <iostream> using namespace std; // Print array elements greater than average void printAboveAvg(int arr[], int n) { // Find average double avg = 0; for (int i = 0; i < n; i++) avg += arr[i]; avg = avg / n; // Print elements greater than average for (int i = 0; i < n; i++) if (arr[i] > avg) cout << arr[i] << " "; } // Driver program int main() { int arr[] = { 5, 4, 6, 9, 10 }; int a = sizeof(arr) / sizeof(arr[0]); printAboveAvg(arr, a); return 0; } |
