Answer Posted / himanshu
Well this is what I tried to make it more simple, no list...
just checking and calling functions.
int calculate_prime(int prime_no)
{
int check,count=0;
while(prime_no != 0)
{
check=check_prime(prime_no);
if (check == 0)
count++;
prime_no--;
}
return count;
}
int check_prime(int prime_no)
{
int num,prime_check=0;
num=prime_no/2;
while(num > 1)
{
if( (prime_no%num) == 0 )
{
prime_check=1;
break;
}
num--;
}
return prime_check;
}
void main()
{
int a;
//TEST CASE 1:
//PASSING 11 AS ARGUEMENT TO calculate_prime FUNCTION
//PREFERRED OUTPUT SHOULD BE 6
a=calculate_prime(11);
printf("%d",a);
//TEST CASE 2:
//PASSING 10 AS ARGUEMENT TO calculate_prime FUNCTION
//PREFERRED OUTPUT SHOULD BE 5
a=calculate_prime(10);
printf(" , %d",a);
getch();
}
