Q 11 - Which of the following is true about call by value method of parameter passing in Go?

A - This method copies the actual value of an argument into the formal parameter of the function.

C - Both of the above.

D - None of the above.

Q 12 - Which of the following is true about call by reference method of parameter passing in Go?

A - This method copies the address of an argument into the formal parameter.

B - Inside the function, the address is used to access the actual argument used in the call.

C - Changes made to the parameter affect the argument.

D - All of the above.

B - false

Q 15 - Method are special functions with a receiver in Go.

A - true

B - false

Q 16 - Which of the following is true about local variables in Go?

A - Variables that are declared inside a function or block are called local variables.

B - They can be used only by statements that are inside that function or block of code.

C - Local variables are not known to functions outside their own.

D - All of the above.

Q 17 - Which of the following is true about global variables in Go?

A - Global variables are defined outside of a function, usually on top of the program.

B - The global variables will hold their value throughout the lifetime of your program.

C - A global variable is available for use throughout your entire program after its declaration.

D - All of the above.

Q 18 - Which of the following is true about formal parameters in Go?

A - Function parameters, formal parameters, are treated as local variables with-in that function.

B - They will take preference over the global variables.

C - Both of the above.

D - None of the above.

Q 21 - Which of the following is correct about nil pointer in Go?

A - Go compiler assign a Nil value to a pointer variable in case you do not have exact address to be assigned.

B - Nil value assignment is done at the time of variable declaration.

C - A pointer that is assigned nil is called a nil pointer.

D - All of the above.

Q 22 - Can you define a pointer to pointer in Go?

A - true
