write a program to find the largest elements of a given array with an index.

Write C a program to find the largest elements of a given array with an index.

Writing a C program to find the largest element of a given array with an index means creating a program in the C programming language that takes an array of integers as input, finds the largest element in the array, and returns the index of that largest element.

To do this, we can initialize two variables: max_elem and max_index. We can then loop through the array, comparing each element to max_elem. If the current element is greater than max_elem, we update max_elem to the current element and max_index to the current index.

At the end of the loop, max_elem should contain the largest element in the array, and max_index should contain its index. We can then output these values to the user.

Find the Largest Element of an Array with Its Index in C

#include<stdio.h>

int main() {
    int arr[] = {10, 20, 30, 40, 50};
    int n = sizeof(arr) / sizeof(arr[0]);
    int max_elem = arr[0];
    int max_index = 0;

    // Find the largest element and its index
    for (int i = 0; i < n; i++) {
        if (arr[i] > max_elem) {
            max_elem = arr[i];
            max_index = i;
        }
    }
    
    // Print the largest element and its index
    printf("The largest element is %d and its index is %d\n", max_elem, max_index);
    
    return 0;
}

Output of the C program you provided is:

The largest element is 50 and its index is 4

This is because the largest element in the array arr is 50, and it is located at index 4.

In this program, we first declare an integer array arr and initialize it with some values. We then calculate the size of the array and initialize max_elem to the first element of the array and max_index to 0.

We then loop through the array using a for loop and compare each element to max_elem. If the current element is larger than max_elem, we update max_elem and max_index accordingly. Finally, we print the largest element and its index using the printf function.

This program demonstrates how to find the largest element of an array along with its index using C.
