It will. Use this: http://www.cplusplus.com/reference/clibrary/cstdlib/srand/

and what can i do so that it generates only 6 digit number???

The modulo operator is % in C++. However, note that you might need to combine the results of several rand() calls depending on how large RAND_MAX is.

so how can i stop it to repeat numbers?

When you call srand, use a different seed value.
