May 2, 2025 · The rand() in C++ is a built-in function that is used to generate a series of random numbers. It will generate random numbers in the range [0, RAND_MAX) where RAND_MAX is a constant whose default value may vary but is granted to be at least 32767.

Random Number. You can use the rand() function, found in the <cstdlib> library, to generate a random number:

This is a basic way to generate random numbers. The line of code that uses static_cast seeds the random number generator based on the current time, which means you get more numbers besides between 0 and 10 instead of just one.
