Something similar to this might work for you;
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main (int argc, const char* argv[])
{
string lines[70];
fstream file("C:\\Temp\\file.txt");
string line;
int index = 0;
while(getline(file, line) && index < 70)
{
lines[index++] = line;
}
string splitLines[10][10];
for(int i = 0; i < index; ++i)
splitLines[i / 10][i % 10] = lines[i];
return 0;
}
Hope this helps,
Fredrik
