Write a C program to read 20 numbers from the keyboard and find the maximum, minimum, 2nd maximum, 2nd minimum, sum, and average of 20 numbers.
#include
int main()
{
int number[30];
int i, j, a,large,small,avg,sum=0;
printf("Enter the numbers \n");
for (i = 0; i < 20; ++i)
scanf("%d", &number[i]);
for (i = 0; i < 20; ++i)
{
for (j = i + 1; j <20; ++j)
{
if (number[i] < number[j])
{
a = number[i];
number[i] = number[j];
number[j] = a;
}
}
}
printf("The numbers arranged in descending order are given below \n");
for (i = 0; i < 20; ++i)
{
printf("%d\n", number[i]);
}
printf("The 2nd largest number is = %d\n", number[1]);
printf("The 2nd smallest number is = %d\n", number[20 - 2]);
large=small=number[0];
for(i=1; i<20; ++i)
{
if(number[i]>large)
large=number[i];
