Question

What do you mean by expression ""a = 5"" ?

Answer 1

Answer:

means the value of a is 5

Answer 2

Value of 5 is allotted to "a"

Explanation:

So now we have to analyze what a =5 actually does.

So before a value is assigned to a variable, the variable has to be declare.

Note: Some programming language allow the programmer to assign values

Declaration:

Assume that a is an integer and it is declared as "int a;"

The above statement, creates a memory space for "a". The amount of memory space will be decided based on the data type. integer will occupy space lesser than "double".

Initialization:

when a = 5 statement is encountered, the number "5" is written on the memory.

Fetching values:

When "print a" is encountered, the variable "a's" memory is identified and then the value is fetched.
