Accessing data in structs

[mkb555]

I haven't coded in awhile, and apparently I'm REALLY rusty because I seem to have forgotten something about structs. I created some simple code to refresh my memory:

#include <iostream>
#include <vector>

using namespace std;

struct p
{
	int b;
};

int main(int argc, char *argv[])
{
        vector<p> plist;
	for (int i = 0; i < 3; i++)
	{
		p test;
		p.b = i;
                plist.push_back(test);
	}
}

I thought you could access data members of a struct simply by using the dot operator (p.b = i), but its giving me a compilation error at that line (17). Clearly I've forgotten something very basic, can anyone help out?

test.b = i;

Uuuuugh, I'm such an idiot. Thank you.
