Hi, I'm trying to read in a text file line by line, taking each line in as a string in C++. Unfortunately, when I run it in the terminal, the line wraps around and is cut into two. Even when I zoom out, the terminal still does this. Anyone know how to make it take in more lines???!!!
Also, I have a problem where when I cout the vector of strings where it is in bold, I get what I want, but when I create a for loop at the end of the program to cout it, it puts the last few lines at the beginning of the vector...
This is my code so far.
Code:
#include <fstream>
#include <sstream>
#include <string>
#include <iomanip>
#include <cstring>
#include <iostream>
#include <vector>
using namespace std;

cout << "Enter file: ";
cin >> filename;
datafile.open(filename);
string line;
int j=0;
int q=0;
int numFA=0;
int nummiss=0;
int numhit=0;
int numtarget=0;
bool hit2ndlast = 0;
bool hitlast=0;
size_t targetloc;
size_t responseloc;
string str1= "Response" ;
string str2= "Target";
string str;
char charline[80];
vector<string> tokens;
vector<int>responseline;
if (datafile.is_open())
{
while (! datafile.eof())
{
getline (datafile, line);
vector<string> returned_strings;
char* current_token =strtok(const_cast<char*>(line.c_str()), " ");
while (current_token != NULL)
{
returned_strings.push_back(string(current_token));
tokens.push_back(string(current_token));
current_token = strtok(NULL, " ");
}
for (unsigned int i = 0; i < returned_strings.size(); ++i)
{
tokens[i] = returned_strings[i];
//cout << tokens[i]<<endl;
j++;
}
}
datafile.close();
}
