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.

Data Types – Sizes & Memor C++.

Image
Data types in C++ specify the type of data that can be stored in a variable. They also determine the size of the memory allocated for the variable. Here are some additional details about the memory usage of data types in C++: • Char: A char variable is used to store a single character. It is typically represented as a single byte in memory. • Short: A short variable is used to store a small integer value. It is typically represented as two bytes in memory. • Int: An int variable is used to store a general-purpose integer value. It is typically represented as four bytes in memory. #30DaysOFCreative

Whitespace in C++

Image
  Whitespace in C++: A line containing only whitespace, possibly with a comment, is known as a blank line, and C++ compiler totally ignores it. Whitespace is the term used in C++ to describe blanks, tabs, newline characters and comments. Whitespace separates one part of a statement from another and enables the compiler to identify where one element in a statement, such as int, ends and the next element begins. Statement 1 In the above statement there must be at least one whitespace character (usually a space) between int and age for the compiler to be able to distinguish them. Statement 2 In the above statement 2, no whitespace characters are necessary between fruit and =, or between = and apples, although you are free to include some if you wish for readability purpose.
