Firstly be mercyful, i'm a beginner in C++.
I wrote this code for my interpreter: Reading a line from source and splitting line to words. I using a vector object for storing words. Here is the code, Source is file descriptor (ifstream):
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
using namespace std;
typedef unsigned int UIntegerP;
#define V(X, Y, Z) X##Y##Z
#define Version V(0, 0, 1)
#define Free 0x0
int main(int ACount, char *Arguments[]){
if(ACount < 2){
cout << "Venus Interpreter - Engine V: " << Version << " - Interprate: -I <Source> \n";
}else{
if(Arguments[1][0] == '-' && Arguments[1][1] == 'I'){
if(ACount < 3){
cout << "Error: No input files \n";
}else if(ACount > 3){
cout << "Error: Too much arguments \n";
}else{
ifstream Source(Arguments[2]);
if(Source.good()){
# define __TEST__ 1
string Line;
vector<string> Words;
string Word;
while(getline(Source, Line)){
for(unsigned long Index = 0; Index <= Line.length(); Index++){
if(Line[Index] == ' ' or Line[Index] == '\0'){
Words.push_back(Word); //Inject the Word to Words
Word.clear();
} else {
Word += Line[Index];
}
}
# if __TEST__
cout << Words[0] << "\n";
# endif
//Interpration starts here
Words.clear();
}
}else{
cout << "Error: File does not exist \n";
}
Source.close();
}
}else{
cout << "Error: Unknown operand \n";
}
}
return 0;
}
And this is the file interpreted by program:
10 * 20 / 5 * 10
Asparagas
And this is the output:
10
10
Like you can see here, value is duplicated. What is the problem?

Answer 1

You problem is that for the line 10 * 20 / 5 * 10 you insert the words into your vector, and then print out its first element
#if __TEST__
cout << Words[0] << "\n";
#endif
You then (I assume) think that you are clearing the vector with the following line
Words.empty();
However, this doesn't clear the vector, it returns a boolean showing whether the vector is empty or not (documentation on vector.empty())
To clear your vector you should use vector.clear()
The second time around your loop, when you're processing asparagus, you print the first element in the vector, which is 10, because it's still in the vector from the first getline
