(C ++ / JAVA) prime number problem

Number (C ++ / JAVA) outputs all prime numbers between 101-200 and outputs primes

C++:

#include<iostream>
using namespace std;
bool ISSS(int p) {
	for (int q = 2; q <= sqrt(p); q++) {
		if (p % q == 0) {
			return false;
		}
	}
	return true;
}
void SUSHU(int m, int n) {
	int num = 0;
	for (int p = m; p <= n; p++) {
		if (ISSS(p) == true) {
			num++;
			cout << p << " ";
		}
	}
	cout << endl;
	cout << num << endl;
}
int main(){
	SUSHU(101,200);
}
