Answer
They lead to tightly coupled and error-prone code.
Global variables are accessible from anywhere in the program, which can lead to unexpected modifications and makes debugging difficult. Instead, use local variables or pass data explicitly. For example, instead of a global `double taxRate`, pass it as a parameter: `calculateTotal(double price, double taxRate)`. This encapsulates functionality and maintains cleaner code.
