C program to find first & second largest number in array

        Array: 3, 10, 80, 20, 5

        Max1: 80

        Max2: 20

Logic:

        1. Input size and elements in array, store it in some variable say size and arr.

        2. Declare two variables max1 and max2 to store first and second largest elements.

        Store minimum integer value in both i.e. max1 = max2 = INT_MIN.

        3. Iterate though all array elements, run a loop from 0 to size - 1.

        4. Inside loop, check if arr[i] > max1

                max2 = max1

                max1 = arr[i]

        5. Else if arr[i] > max2 && arr[i] < max1

                max2 = arr[i]

#include<stdio.h>

#include <limits.h>

int main()

{

        int size, arr[100], i, max1, max2;

        scanf("%d", &size);

        for(i = 0; i < size; i++){

                scanf("%d", &arr[i]);

        }

        max1 = max2 = INT_MIN;

        for(i = 0; i < size; i++){

                if(arr[i] > max1){

                        max2 = max1;

                        max1 = arr[i];

                }

                else if(arr[i] > max2 && arr[i] < max1){

                        max2 = arr[i];

                }

        }

        printf("%d %d\n", max1, max2);

        return 0;

}
