Basic Data Types
In C++, data types can be classified into various categories. This is as shown in the figure below:
- The C and C++ compilers support all the built-in data types.
- The basic data types could have many modifiers preceding that will serve the needs of various situations.
- The modifiers signed, unsigned, and modifier long may be applied to double also.
- Also, the void has no preceding modifies.
- In C++ data type representation is machine specific.
| Data Type | Size | Range |
|---|---|---|
| char | 1 byte | -127 to 127 or 0 to 255 |
| unsigned char | 1 byte | 0 to 255 |
| signed char | 1 byte | -127 to 127 |
| int | 4 byte | -2147483648 to 2147483647 |
| unsigned int | 4 bytes | 0 to 4294967295 |
| signed int | 4 bytes | -2147483648 to 2147483647 |
| short int | 2 bytes | -32768 to 32767 |
| unsigned short int | Range | 0 to 65,535 |
| signed short int | Range | -32768 to 32767 |
| long int | 4 bytes | -2,147,483,648 to 2,147,483,647 |
| signed long int | 4 bytes | Same as long int |
| unsigned long int | 4 bytes | 0 to 4,294,967,295 |
| float | 4 bytes | +/- 3.4e +/- 38 7digits |
| double | 8 bytes | +/- 1.7e +/- 308 15digits |
| long double | 8 bytes | +/- 1.7e +/- 308 15digits |
| wchar_t | 2 or 4 bytes | 1 wide character |
