0.#define MALLOC (n, type) \sizeof(type))1. Macros can be defined like functions, such as:#define MIN (x, y) (xBut in the actual use, only when writing min (), must be parentheses, Min will be as a macro expansion, otherwise do not do any processing.

The dichotomy method is a method for solving the approximate root of an equation. For a functionF (x)F(X), using the dichotomy method to find outF (x)F(X) Approximate solution, we first set an iteration interval (in this topic, we then give the two
