Step 1: Function Prototype
`int add(int a, int b);`
In C++, a function prototype is a declaration of a function that specifies its name, return type, and parameters, but does not provide the function's implementation. It allows the compiler to know the function's interface before it is actually defined. Here's an example of a function prototype:
Step 2: Built-in Functions
* $$`strlen`$$: Length function in the string library
Built-in functions are pre-defined functions provided by the C++ standard library. They can be used to perform various tasks, such as input/output operations, mathematical calculations, and string manipulations. Examples of built-in functions include:
Final Answer
Function prototype: A declaration of a function that specifies its name, return type, and parameters. Built-in functions: Pre-defined functions provided by the C++ standard library for various tasks. Function overloading: A feature in C++ that allows multiple functions with the same name to have different parameter lists. Pointer: A variable that stores the memory address of another variable. Class: A user-defined data type that encapsulates data and functions that operate on that data. Constructor: A special function that is called when an object is created to initialize its data members and set up its state.
