Then, this program displays the largest element of that array using loops. This program takes n number of elements from user and stores it in array arr[]. To find the largest element, the first two elements of array are checked and largest of these two element is placed in arr[0]. Then, the first and third elements are checked and largest of these two element is placed in arr[0]. This process continues until and first and last elements are checked. After this process, the largest element of an array will be in arr[0] position. #include <iostream> using namespace std; int main() { int i, n; float arr[100]; cout << "Enter total number of elements(1 to 100): "; cin >> n; cout << endl; // 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]; } cout << "Largest element = " << arr[0]; return 0; }
