Byte short char
WebData types like byte, short, int, and long fall under this category of data types. Byte: Byte data type in java can store numbers falling in the range of -128 to 127. Whenever we want to save memory, the byte data type can be used as it consumes less memory as compared to the int data type. ... char: 2 bytes: It can be used for storing only a ... The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long. The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. The actual size of the integer types varies by implementation. The standard requires only size relations between the data types and minimum sizes for each data type:
