What difference between rand() and random() functions?

Question

Once, my teacher taught me to use randomize() and random() function for generating pseudorandom numbers in C++ Builder. Now I prefer working in VS

Answer 1

srand() is the C Standard library implementation for seeding the (pseudo) random number generator. rand() is the (pseudo) random number generator in the C Standard Library.

C++ has implemented a newer (pseudo) random number generator in the header file, which has a variety of different engines to use: http://en.cppreference.com/w/cpp/numeric/random
