In this example, you will learn to find the largest element of an array. The program will ask to enter an array of integers and then will find the largest element from the given array.
Example: Find Largest Element in an Array

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |
#include <iostream> using namespace std; int main() { int i, n; float arr[100]; cout << "Enter total number of elements: "; cin >> n; // Store number entered by the user for(i = 0; i < n; ++i) { cout << "Enter Number " << i + 1 << " : "; cin >> arr[i]; } // Loop to store largest number to arr[0] for(i = 1;i < n; ++i) { // Change < to > if you want to find the smallest element if(arr[0] < arr[i]) arr[0] = arr[i]; } //print the largest element cout << "Largest element in an array: " << arr[0]; return 0; } |
When you run the program, the output will be following:
|
1 2 3 4 5 6 7 |
Enter total number of elements: 5 Enter Number 1 : 13 Enter Number 2 : 15 Enter Number 3 : 35 Enter Number 4 : 87 Enter Number 5 : 64 Largest element in an array: 87 |
