Thread: Program the prints prime numbers

I need to make a program that prints all prime numbers between 3 and 100.
Here is my code so far. Right now it only outputs the number 3. What is wrong with it? Thanks for any help.

Code:

#include<iostream>
using namespace std;

int main()
{int num=3, checknum, remainder, answer=1;
	do{checknum=2;
		while(checknum<num-1)
		{remainder=num%checknum;
		if(remainder==0)
		{answer=0;
		continue;}
		else
		answer=1;
		checknum++;
		}
		if(answer=1)
		{cout<<""<<num;}
		num++;
	}while(num<101);
	return 0;
}
