Easy Probelm to Fix

I believe the problem has something to do with the code below.

void organizeList(std::vector<Contact> &c1) {
	std::vector<Contact>::iterator iter = c1.begin();
	std::vector<Contact> temp;
	for(char a = 'A'; a <= 'Z'; ++a) {
		for(iter; iter != c1.end(); ++iter) {
			if((*iter).getLastC() == a)
				temp.push_back(*iter);
		}
	}
	while(!c1.empty())
		c1.pop_back();
	for(iter = temp.begin(); iter != temp.end(); ++iter)
		c1.push_back(*iter);
}

The if statement's condition is not being met unless the lastName is equal 'A'. Why isn't it running through the for loop like it's supposed to? It's obviously something I did wrong.

void organizeList(std::vector<Contact> &c1) {
	std::vector<Contact>::iterator iter = c1.begin();
	std::vector<Contact> temp;
	for(char a = 'A'; a <= 'Z'; ++a) {
		for(iter; iter != c1.end(); ++iter) { // What value will iter have on the second iteration?
			if((*iter).getLastC() == a)
				temp.push_back(*iter);
		}
	}
	while(!c1.empty())
		c1.pop_back();
	for(iter = temp.begin(); iter != temp.end(); ++iter)
		c1.push_back(*iter);
}

*facepalm*

I don't know how I didn't see that before.

void organizeList(std::vector<Contact> &c1) {
	std::vector<Contact>::iterator iter = c1.begin();
	std::vector<Contact> temp;
	for(char a = 'A'; a <= 'Z'; ++a) {
		for(iter = c1.begin(); iter != c1.end(); ++iter) { 
			if((*iter).getLastC() == a)
				temp.push_back(*iter);
		}
	}
	while(!c1.empty())
		c1.pop_back();
	for(iter = temp.begin(); iter != temp.end(); ++iter)
		c1.push_back(*iter);
}

Thanks. :)
