Please help! I'm trying to write a function that determines if a number is prime to use this function to determine and prints all prime numbers between 1 and 100. This is what I have so far:
#include <stdio.h>
int prime(int num)
{
int sw = 1;
int count:
}
for( count = num-1; count >=2; count--);
scanf("%d", &prime);
printf("%d\n", count, sw=1);
return 0;
}
