Program to find largest element in an array

Program to find largest element in an array

Given an array, find the largest element in it.

#include <stdio.h>

 // C function to find maximum in arr[] of size n

int largest (int arr[], int n)

{

    int i;

    // Initialize maximum element

    int max = arr[0];

    // Traverse array elements from second and

    // compare every element with current max 

    for (i = 1; i < n; i++)

        if (arr[i] > max)

            max = arr[i];

return max;

}

int main()

{

    int arr[] = {10, 324, 45, 90, 9808};

    int n = sizeof(arr)/sizeof(arr[0]);

    printf("Largest in given array is %d", largest(arr, n));

return 0;

}

Output:

Largest in given array is 9808

Example:

Input: arr[] = {10, 20, 4}

Output: 20

Input: arr[] = {20, 10, 20, 4, 100}

Output: 100
