Code:
#include
#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
