Why can't the vector catch the last term

[calvinfornia]

Hi, I'm working on a project reading in a boolean function from a .txt file.
The .txt file is like:

ABcD+ABCD+aBcD+aBCD.
A 0.2
B 0.4
C 0.6
D 0.8

The number stands for the probability of variable being 0.
The goal is to partition the boolean function into several minterms.
In this case, I want to get ABcD, ABCD, aBcD, aBCD four terms.
My code so far is:

#include <bits/stdc++.h> 
#include <iostream>
#include <fstream>
#include <string>
#include <sstream> 

using namespace std; 


int main()
{	
	string str("ABcD+ABCD+aBcD+aBCD.");
	for (int i = 0; i < str.size(); i++)
	{
		cout << str[i] << endl;
	}
	
	vector<string> minterm_list;
	stringstream ss;
	string minterm;
	char c;
	
	ss << str;
	while(ss >> c)
	{
    	if(c =='+')
    	{ 
			minterm_list.push_back(minterm);
			minterm = "";
    	}
		else
    	{
    		minterm = minterm + c;
    	}
	}
	
	cout << "There are " << minterm_list.size() << " minterm in total" << endl;
	for(int i=0; i < minterm_list.size(); i++)
	{	
		cout << minterm_list[i] << endl;
	}
	
return 0;
}

And the output is

A
B
c
D
+
A
B
C
D
+
a
B
c
D
+
a
B
C
D
.
There are 3 minterm in total
ABcD
ABCD
aBcD

Why isn't the fourth term aBcD not pushed by the vector?
Thx in advance!

Add the line
if ( !minterm.empty() ) minterm_list.push_back(minterm);
after the end of the while loop, or you won't catch what's left in at the end.

For goodness' sake, STOP CREATING NEW THREADS FOR THE SAME PROBLEM.

I've figured out the problem and modified the if-else condition and get the correct result.

else if(c == '.')
    	{
    	      minterm_list.push_back(minterm);
	      minterm = "";
	} 

A
B
c
D
+
A
B
C
D
+
a
B
c
D
+
a
B
C
D
.
There are 4 minterms in total, which are :
ABcD
ABCD
aBcD
aBCD
