Study Notes
Data Types in C++ Programming
- A data type is a set of values together with a set of operations.
- C++ data types can be categorized into three main categories.
Primary Data Types (Simple)
Integer Data Type
- Keyword:
int - Requires 4 bytes of memory space
- Range: -2147483648 to 2147483647
- Examples: -6728, 0, 78, +763
- Positive integers do not need a + sign
- Commas are not used within an integer, but are used to separate items in a list
Character Data Type
- Keyword:
char - Requires 1 byte of memory space
- Range: -128 to 127 or 0 to 255
- Used for characters: letters, digits, and special symbols
- Each character is enclosed in single quotes
- Examples: 'A', 'a', '0', '*', '+', '$', '&'
- A blank space is a character and is written ' ', with a space left between the single quotes
- Example declaration:
char test = 'h'; char case = 'A';
Boolean Data Type
- Keyword:
bool - Used for storing boolean or logical values
- Can store either
trueorfalse
