Learn how to generate a random number in C++ with std::mt19937. Choose inclusive integer bounds, draw floating-point values, use fixed seeds for repeatable tests, or seed with random_device.

C modulus explains what the % operator returns, which integer types it accepts, how quotient and remainder relate, and how to test divisibility, parity, wrapping, and negative values.

Learn how to print a new line in Python: print() adds a newline automatically, \n embeds one in a string, and end controls what follows. See the next line in Python with runnable examples.

Learn how to print in C with printf using a complete, compilable program. Print text, strings, characters, integers, and floating-point values, then handle newlines and catch format warnings.

C enum declarations create named integer constants. Learn implicit and explicit values, typedef variables, duplicate values, and a practical switch example with precise type behavior.

C++ stringstream lets you format values into a string with >. Learn str(), stream state checks, leftover input, and how to clear and reuse the stream safely.

Learn maps in C++ with one compilable std::map example: declare key-value types, insert and update entries, look up and erase keys, and traverse safely with iterators.
