Lottery code won't stop!

#include<iostream>

using namespace std;


int main()

int num;

srand(time(NULL));
num = rand() % 7 + 1;

if (pick2 < num)
cout << "That number is too small. Try one more time!\n";
}
cout << "Final pick\n";

cin >> pick3;
{
if (pick3 == num)
win + 1;

cout << "You got it! You win the prize!\n";

if (pick3 > num)
win + 1;
cout << "That number is too big. Sorry. You lose.\n";

if (pick3 < num)
win + 1;

}

while (win = 0);
system("pause");

}



}




Sorry if I couldn't convert the code to code text.

I've got this lottery thing that won't stop if the right number is picked. If the right number is picked, I want it to stop, but if the 1st try is right, it moves on to the 2nd try, and if the 2nd try is right, it moves onto the third. Is there something wrong with my while loop?

Please modify the code so it will work and explain why it will work.

Thank you!

Highlight your code and on the right hand side you should see

Format:

tab. The first option is source code. Click that with your code highlighted and it should convert it into something read-able.

P.S. The first obvious sign your do{}while loop is broken is in the while statement you have while(win = 0); this should be while(win == 0);

= is an assignment
== is a comparison
