In C++, the "*" (multiplication) operator has higher precedence than the "&&" (logical AND) operator. This means that when evaluating expressions, the multiplication operator will be evaluated before the logical AND operator. Understanding operator precedence is crucial for writing correct and efficient C++ code.

Using too many inline functions can lead to memory bloat. When functions are inlined, their code is duplicated wherever they are called. This can lead to an increase in the size of the compiled code and, consequently, higher memory consumption.

David should implement the "Switch" statement for his calculator program. It's designed for scenarios where multiple options need to be considered based on a single variable's value (in this case, the user's input).

When global variables are declared outside all functions, they have static storage duration by default. Static storage duration means they exist for the entire program's lifetime.

The data type used for storing raw memory addresses is intptr_t, which is an integer type designed to hold a memory address. It ensures that memory addresses are correctly represented, allowing you to work with pointers and addresses in a portable way.

The term for the actual body of a function where detailed processing statements are written is "Implementation." It's in the implementation that you provide the logic and functionality for the function. The other options have different meanings: Prototype is a declaration of the function, Definition is a broader term encompassing various aspects of a function, and Signature refers to the function's name and parameter list.

In C++, when a case within a switch statement doesn't contain a break statement, it leads to fall-through behavior. This means that execution will continue from the matched case statement to the subsequent case(s) until a break is encountered or the switch block ends. It's a powerful feature for handling multiple cases with the same code, but it should be used intentionally.

In C++ and many other programming languages, the "else" keyword is used to specify a block of code that should be executed when the condition in an "if" statement is false. It's commonly used to provide an alternative action when the condition isn't met.

When you provide the necessary details about a function without its actual implementation, it's called "Definition." In a function definition, you specify the function's name, return type, parameter list, and what the function should do when called. The other options have different meanings: Declaration is a statement that tells the compiler about a function's name and signature, Invocation is the act of calling a function, and Execution is the process of running the function's code.

In most programming languages, including C++, multiplication (*) takes precedence over addition (+). So, in the given expression, c * d will be performed first.
