Help with Lexical Analyzer

Question

Good evening everyone. I’m implementing a c/c++ lexical analysis, but I’m having a problem with the output. I was asked to leave the program with only 3 variables and 2 operands, plus 1 delimiter and 1 equality.

But I’ve tried everything and I can’t do it. If I put to print only 3 variables, the program "eats" one of them. Below follows the code of what I have already done. This analyzer will have to deliver tomorrow, so if anyone can help me I will be very grateful.

#include <stdlib.h> 
#include <string.h> 
#include <iostream> 
#include <iomanip> 
using namespace std; // contexto onde estão definidos macros e variáveis.
