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

Writing a C program to find the smallest element of a given array with its index means creating a program in the C programming language that can read an array of integers as input and then determine the smallest value in the array along with its index. The program should be able to iterate through the array elements, compare them with each other, and keep track of the index of the smallest element. Finally, the program should print out the smallest element of the array and its index to the console.

C to find the smallest element of a given array along with its index:

C programming

#include 

int main() {
    int arr[] = {10, 20, 30, 40, 5};
    int min_elem = arr[0]; // initialize min_elem to first element of array
    int min_index = 0; // initialize min_index to 0
    int size = sizeof(arr) / sizeof(arr[0]);

    // Find the smallest element and its index
    for (int i = 0; i < size; i++) {
        if (arr[i] < min_elem) {
            min_elem = arr[i];
            min_index = i;
        }
    }

    // Print the smallest element and its index
    printf("The smallest element is %d and its index is %d\n", min_elem, min_index);
    return 0;
}

Output of the C program you provided is:

The smallest element is 5 and its index is 4

This is because the smallest element in the array arr is 5, and it is located at index 4.

In this program, we first initialize min_elem to the first element of the array and min_index to 0. We then loop through the array using a for loop and compare each element to min_elem. If the current element is smaller than min_elem, we update min_elem and min_index accordingly. Finally, we print the smallest element and its index.

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