Problems in the Code with if command.

Hello everybody. I have difficulties with a C code

Code:

` #include<stdio.h>`

int main()

{

int primes[4];

int counter=1;

int start=3;

int prime;

int i;

primes[0]=2;

printf("2");

while(counter<4)

{

prime=1;

for(i=0; i<counter&′ i++)

if((!start%primes[i]))

prime=0; // here is my problem

if(prime) // How if works ???? prime = 0

{

printf("\n%d",start);

primes[counter++]=start;

}

start++;

}

printf("\n");

return 0;

}

I pose/put the value 0 in prime variable and after that I put it into if

how works??? From theory I knew that if command stops to work when find a zero value. And now the prime is 0!!!!!

Thank in advance. :)
