srand and 64bit time_t in VisualStudio

Hi I'm a beginner of C (and coding in general), trying to generate easy random numbers in visual studio.

However it seems that due to my system being 64bit, srand(time(NULL)) do not work.

After some searching, I tried srand((unsigned int)time(NULL)) too but the compiler still gave an error message (about srand returning void value).

Is there anyway to bypass this problem?

std::srand only initialises the random number generator to a specific point along the pseudo-random sequence. It doesn't return anything. You need to call std::rand to actually get a number.
