Homework Statement
I am attempting to transfer the data from a file into a 2D vector array. The data look like this:
1 2 3
4 5 6
7 8 9
However, the dimensions must be detected dynamically.
Homework Equations
The Attempt at a Solution
There are two files in this code, but I attempted to transfer only one of them. I tried to read line by line and then take each word and push it into the array of vectors. The program does not compile though.
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
#include <vector>
using namespace std;
int main ( ) {
ifstream infile1;
ifstream infile2;
infile1.open ("Array.txt");
infile2.open ("Pattern.txt");
if (!infile1||!infile2) {cout<<"error"; return -1;}
string line; string word;
vector<vector<string>>a();while (!infile1.eof())
{
getline (infile1, line);
istringstream stringline (line);
while ( stringline >> word ) {
istringstream strw (word);
a.push_back(strw); //the error is here. The "a." specifically.
}
return 0;
}
