Why is this do while loop infinitely executing?

Why is this do while loop infinitely executing?

#include "stdafx.h"
#include <iostream>
using namespace std;
int main()
{
unsigned int base;
cout << "Base: ";
cin >> base;
for (int i = 1; i <= base; i++) {
    int j = 0;
    do {
        cout << "#";
        j++;
    } while (j = i);
    cout << endl;
};
system("pause");
// keep on building up until you reach 'base'
return 0;
}

I am really confused about this. This program is supposed to create a triangle like this

#
##
###

(user inputs bottom number, so in this example the base = 3) Anybody help fix my rookie mistake?

You might wanna try while (j == i);.

j = i is a variable declaration/assignment which will always be true as long as it succeeds. It seems like you want to compare the two, so use the equal to operator: ==.

Edit: Made a typo and therefore the same mistake as your question shows. Fixed that.
