Answer 2

Ex. in C++:
std::string myName;
This code initializes a *variable* of *type* std::string and *identifier* myName. These are the codewords to define a variable. The identifier of a variable is just its name.

Answer 3

Variable - stores data of a particular type
int x = 46;
'x' is identifier of x variable (It gets kinda confusing if you think like that. just remember the following)
Identifier - name of a variable/class/function
