1- How many arguments can a C++ function have? a) One. b) Two. c) Three. d) Unlimited 2- What is a variable scope? 3. If the following lines of code have errors, correct them: otherwise, write "no errors" float 1_b=5.5; int a_1-b: cout<ca return 0: 4- Is it possible to call a function from inside a function? (Yes or No) 5- When de we need to use private keyword in C++ class? 6- A derived class can be a base class for other classes. (True or False) 7- Retum by value is better than return by reference (True, False or it depends on the case) 8- Is it possible to alter the address that the reference points to? (Yes or No) 9. We can write as many copy constructor in a C++ class as we want. (True or False) 10-Syntax error is logical errors (harder than, equal in difficulty to, simpler than) 11-Create an instance of the following class and call its methods. template celans D, int I, int J elass Arrsy2D I publie: D set (conat int 1, const int 3, const D val) i arr(4) (4 - val: D get (const int i, conat int 3) t retarn arr(1) (1): 12- What is a null pointer? 13-Every C++ class has a default constructor. (True or False) 14- In C+, every line must end with a semicolon. (True or False) 15- What is template specialization?
