Answer 1

Answer:

sorry i dont know what answer

Answer 2

Answer:

Explanation:

Constant variables need not be defined as they are declared and can be defined later- This statement is false.

You cannot update or modify any variable whose value remains the same throughout your application. At the time of its declaration, a constant variable must be initialised. In C++, the keyword const is put before the variable's data type to declare a constant variable.

A mistake occurs from not declaring and defining the constant variable at the same time. As a result, assertion an is untrue.

Any variable which have a constant value of your programme that cannot be updated or modified. At the time of its declaration, a constant variable must be initialised. In C++, the keyword const is put before the variable's data type to declare a constant variable.

Therefore, the correct option is Constant variables need not be defined as they are declared and can be defined later.
