It sounds like you got your >> and << mixed up. Like cout>> instead of cout<<.

This should do it:


for(int i = 2; i < 10000; i++)

You declared your strings incorrectly. Instead of string name1[10],name2[10], use string name1,name2.

With the string class name[10] refers to the 10th element of the string. It doesn't create a...

You can use the rand() function in cstdlib to get a random number.

It is used like this:



int x = rand() % 5; //x would be between 0 and 4

Before calling rand(), you should call srand()...
