Data Types - Char And ASCI C++

 Data Types - Char And ASCI C++

ASCII: Representing Characters as Numbers
  • ASCII (American Standard Code for Information Interchange) is a standard character encoding scheme that assigns unique numerical codes to characters.
  • C++ uses ASCII internally to represent characters.
  • The char data type in C++ is used to store single characters, such as letters, digits, symbols, and whitespace.
  • It typically occupies 1 byte of memory.

Example:


Best Practices:

  • Use char to store single characters effectively.
  • Be mindful of ASCII codes for character manipulation and comparison.
  • Consider Unicode for broader character support when needed.

Whitespace in C++

  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.

Data Types - Bool And Void C++

Image
 Data Types - Bool And Void C++ Bool: Representing True or False Purpose: Stores Boolean values, indicating truth or falsehood. Values: Can hold only two possible values:  true  or  false . Common Uses: Decision-making in control structures (e.g.,  if  statements) Loop conditions Function return values Example: void: Representing No Value Purpose: Indicates the absence of a value. Common Uses: Function return types that don't return a value Function parameter lists to specify no arguments

Data Types – Integer C++

Integer data types in C++ are used to store whole numbers. They are typically represented as binary numbers in memory. Integer data types can be used to store a variety of values, such as: • Loop counters • Array indices • Mathematical expressions • Enumeration values • Bit masks
