Let's say I have a file of names such as:
"erica","bosley","bob","david","janice"
That is, quotes around each name, each name separated by a comma with no space in between.
I want to read these into an array of strings, but can't seem to find the ignore/get/getline/whatever combo to work. I imagine this is a common problem but I'm trying to get better at file I/O and don't know much yet. Here's a basic version that just reads in the entire file as one string (NOT what I want, obviously):
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
fstream iFile("names.txt", ios::in);
string names[5];
int index = 0;
while(iFile)
{
iFile >> names[index];
index++;
}
for(int i = 0; i < 5; i++)
{
cout << "names[" << i << "]: " << names[i] << endl;
}
Output:
names[0]: "erica","bosley","bob","david","janice"
names[1]:
names[2]:
names[3]:
names[4]:
Also, I understand why it all gets read as a single string, but then why are the remaining elements not filled with garbage?
To be clear, I want the output to look like:
names[0]: erica
names[1]: bosley
names[2]: bob
names[3]: david
names[4]: janice
