Modifier Types in C++ Assignment Help
C++ Datatypes along with different basic datatypes that include int, char, double, short int, unsigned char, signed intetc and long double. The words unsigned, long, signed are called type modifiers. C++ allows to use some modifiers for int, char and double types
There are different types of modifiers:
- Signed
- Unsigned
- Short

The signed and unsigned modifiers have different sign of variables. The signed and unsigned variable stores the signed value and unsigned value in the allocated memory. Signed variable takes 1 extra bit compared to unsigned variables. The values of unsigned types start from 0.
Example
Short unsigned j;
Type Qualifiers in C++
A token added to a variable is called a qualifier which adds an extra quality to the programming. The qualifier is an adjective for a variable. The variable itself still occupies the same amount of memory with or without a qualifier and each bit has the same interpretation. Qualifiers specify how it may be accessed and where it is stored. There are three types of qualifiers
- const: that define that the type is constant.
- volatile: that define that the type is volatile.
- mutable: this is applied to non-static classNamemembers of the non-reference non-const type.
Mutable members are modifiable for const classes
