Variable Lifespan in C++

Variable Lifespan:
Variable lifespan refers to the duration of their existence in the program's memory. Variables declared within a block or function scope exist only within that scope and are destroyed when the block or function exits. Understanding variable lifespan is crucial for managing memory and preventing memory leaks.

Variable Naming Rules C++

In C++, variable names are identifiers that must follow specific rules. Here are the key rules for variable naming in C++: •Start with a letter or underscore:  Variable names must start with a letter of the alphabet (A-Z, a-z) or an underscore (_). Letters include both uppercase and lowercase letters. • Use letters, digits, and underscores: Variable names can contain letters, digits (0-9), and underscores (_). However, you cannot use other special characters, such as spaces, punctuation marks, or symbols. • No keywords: Do not use keywords as variable names. Keywords are reserved words in C++ that have special meanings, such as int, for, while, etc. #30DaysOFCreative
