What is variable in c plus plus programming?

Answer 1

A variable is simply a named object whose member value(s) can be changed or mutated. Its type may be primitive such as int, char, float or double, or it may be a user-defined type such as a class, struct, union or enum. Constants are the same as variables except that their immutable member value(s) cannot be changed.

Answer 2

You declare a variable by first defining its data type and then its name followed by a semi-colon. Here is an example:

int variable;

The example above declares an uninitialized integer variable. You can initialize the variable by giving it a value such as "int variable = 1;". It is important to initialize your variables, because you can get errors when executing your program that the variable does not have a value or is uninitialized. Variables that are uninitialized have whatever garbage value happens to be when the program is executed.

Here are all of the data types that a variable can be:

*int - integer value

*char - character value

*bool - boolean value

Answer 3

A variable is a named memory location for which the contents are volatile. The antonym of variable is constant.

Answer 4

A variable is a place to store a value that may change while the a program runs.

Answer 5

Variables are volatile data types, as opposed to constants which are non-volatile data types.

Answer 6

Its type, its value and its memory address.

Answer 7

There are 5 type of variables in C++....
