/* Determine if the numbers between 2 and 9 are prime numbers */

#include

int main()

{

int c, number, i=0;

printf("Enter a number between 2 and 9 ");

scanf("%d", &number);

for ( c = 2; c <= number; c++);

{

if(c % i == 0)

number = number + 1;

}

switch(number)

{

case 2:

case 3:

case 5:

case 7:

printf("You entered a prime number ");

break;

case 4:

case 6:

case 8:

printf("You entered a composite number ");

break;

default:

printf("Invalid value entered. ");

}

return 0;

}

This is the program i wrote for my C problem, I think I'm having difficulty determining if the number is prime. I don't know where I went wrong. It has to be a switch statement.
