random number generator c++ between 0 and 1

To generate a random number between 0 and 1 in C++, you can use the rand() function from the standard library. First, you need to include the <cstdlib> header to use the random number generation functions. Then, you should call srand(time(0)) to seed the random number generator with the current time. Finally, you can use the expression static_cast<double>(rand()) / RAND_MAX to generate a random number between 0 and 1.
