Keywords in C++

Certainly! Here's a breakdown of some important keywords in C++:

1. Data Type Keywords:

 * int: Represents whole numbers (e.g., 10, -5, 0).

 * float: Represents single-precision floating-point numbers (numbers with decimals).

 * double: Represents double-precision floating-point numbers (higher precision than float).

 * char: Represents a single character (e.g., 'a', '!', '$').

 * bool: Represents a boolean value (true or false).

 * void: Indicates the absence of a return value for a function.

2. Control Flow Keywords:

 * if: Executes a block of code if a condition is true.

 * else: Executes a block of code if the condition in the 'if' statement is false.

 * else if: Checks for additional conditions if the initial 'if' condition is false.

 * switch: Selects one of many code blocks to be executed.

 * case: Specifies a value to be compared in a 'switch' statement.

 * default: Specifies the code to be executed if none of the 'case' values match.

 * for: Repeats a block of code a specified number of times.

 * while: Repeats a block of code as long as a condition is true.

 * do-while: Repeats a block of code at least once, then continues as long as a condition is true.

 * break: Exits a loop or 'switch' statement prematurely.

 * continue: Skips the current iteration of a loop and moves to the next one.

3. Access Control Keywords:

 * public: Members declared as 'public' are accessible from anywhere.

 * private: Members declared as 'private' are only accessible within the same class.

 * protected: Members declared as 'protected' are accessible within the same class and its derived classes.

4. Storage Class Keywords:

 * auto: (Default) The storage duration of the variable is determined by its scope.

 * register: Suggests to the compiler that the variable should be stored in a register for faster access.

 * static: The variable retains its value between function calls.

 * extern: Declares a variable that is defined elsewhere.

5. Other Important Keywords:

 * return: Returns a value from a function.

 * sizeof: Returns the size of a data type or variable in bytes.

 * new: Allocates memory dynamically.

 * delete: Deallocates memory that was dynamically allocated using 'new'.

 * this: A pointer to the current object within a class method.

 * const: Indicates that a variable's value cannot be changed after initialization.

 * volatile: Tells the compiler that the value of a variable can change unexpectedly.

 * namespace: Provides a way to organize code and avoid naming conflicts.

 * using: Brings names from a namespace into the current scope.

This is not an exhaustive list, but it covers many of the most commonly used keywords in C++.
