While loop

Question

#include <iostream>
using namespace std;

int main()
{
int num = 1;
while (num < 6) {
cout << "Number: " << num << endl;
num = num++;
}

return 0;
}

i tried num = ++num and the loop stopped after "number 5"

Why does num = num++ create a continous loop without end because it continues to print "number 1" ?

Answer 1

num = num++ =1

And num<6; Loop keeps going over and over.

It doesn't increase.
where
num = ++num=2
and keeps increasing. So when it hits limit it breaks the loop.
