C Program to Find the Largest Two Numbers in a given Array

#include < stdio.h>
#define MAX 4
 
void main()
{
    int array[MAX], i, largest1, largest2, temp;
 
    printf("Enter %d integer numbers \n", MAX);
    for (i = 0; i < MAX; i++)
    {
        scanf("%d", &array[i]);
    }
 
    printf("Input interger are \n");
    for (i = 0; i < MAX; i++)
    {
      printf("%5d", array[i]);
    }
    printf("\n");
    /*  assume first element of array is the first larges t*/
    largest1 = array[0];
    /*  assume first element of array is the second largest */
    largest2 = array[1];
    if (largest1 < largest2)
    {
        temp = largest1;
        largest1 = largest2;
        largest2 = temp;
    }
    for (i = 2; i < 4;	i++)
    {
        if (array[i] >= largest1)
        {
            largest2 = largest1;
            largest1 = array[i];
        }
        else if (array[i] > largest2)
        {
            largest2 = array[i];
        }
    }
    printf("n%d is the first largest \n", largest1);
    printf("%d is the second largest \n", largest2);
    printf("nAverage of %d and %d = %d \n", largest1, largest2,
(largest1 + largest2) / 2);
}

Output

 Enter  4  integer numbers
 80 
 23 
 79 
 58 
Input interger are
 80     23     79     58 
 
 80  is the first largest
 79  is the second largest
 
Average of  80  and  79  =  79
