C++ Program to find the largest and smallest number in an array using the function

---

In this program, You will learn how to find the largest and smallest number in an array using the function in C++.

---

List is :2 3 4 5 10 33 44 55 66 77

Largest & Smallest is: 77 2

Example: How to find the largest and smallest number in an array using a function in C++.

#include<iostream>
using namespace std;

void findNumber(int array[], int size) {

    int lg = array[0];
    int sm = array[0];

    for (int i = 0; i < size; i++) {
        if (lg < array[i]) {
            lg = array[i];
        }

        if (sm > array[i]) {
            sm = array[i];
        }
    }
    cout << "Largest number is:" << lg;
    cout << "\nSmallest number is:" << sm;
}

int main() {

    int array[10], i, size;

    cout << "Enter size of an array:";
    cin>>size;

    cout << "Enter array elements:";
    for (i = 0; i < size; i++) {
        cin >> array[i];
    }

    findNumber(array, size);

    return 0;
}

Output:

Enter size of an array:5
Enter array elements:40 50 10 20 30
Largest number is:50
Smallest number is:10
