Answer 1

1) In C++, the identifier can be the name of a variable or function. Since C++ supports object-oriented programming, the identifier can also be the name of a class and it can be the name of any other user defined data types. The identifier can start with an alphabet and it can be a lowercase or uppercase. The identifier can also start with an underscore. Then it can follow any number of letters, underscores and numbers.

2) It can be declared as

     //A non-negative integer. 
        unsigned int a;
        a = 562;
        cout << a << endl;

        //A short integer
        short int b;
        b = 12;
        cout << b << endl;

        //A Boolean value
        bool c;
        c = true;
        cout << c << endl;
