So open the file, read 10 lines from the file, write to first file, read next 10, write to next file. What is the problem exactly?

No that is not a problem at all. Being a "noob" is meaningless. Either you have tried to do it yourself or not. If you have tried to do it yourself you must have run into some problem. If you have not tried it yourself then this is just being lazy and getting someone to do your own work for you.

This should get you on your way:

The msdn link you provide is for C++/CLI and won't work for generic C++.
Most of the hits at the google search are also C++/CLI.

Solution 2

Check out https://www.google.com/search?q=C%2B%2B+read+a+file[^] for generic C++

I code it in C,

XML

#include<stdio.h>
#include<stdlib.h>
#include<string.h>

int main(int argc, char** argv){
        int i,j;
        char filename[6],context[10];
        strcpy(filename, "0.txt");
        freopen("input.txt","r",stdin);
        for(i=0; i<10; i++){
                filename[0] = '0'+i;
                freopen(filename,"w",stdout);
                for(j=0; j<10; j++){
                        scanf("%s",context);
                        context[strlen(context)] = '\n';
                        printf("%s",context);
                }
        }
        return 0;
}

C++ is the same.
