Question

Explain built in data types in C++ with their size and range​

Answer 1

Explanation:

Built-in types (also called fundamental types) are specified by the C++ language standard and are built into the compiler. Built-in types aren't defined in any header file. Built-in types are divided into three main categories: integral, floating-point, and void.

Integer Types

Type            Storage size                   Value range

signed char          1 byte                           -128 to 127

int                     2 or 4 bytes                     -32,768 to 32,767  

unsigned int     2 or 4 bytes                 0 to 65,535  

short                 2 bytes                         -32,768 to 32,767
