Group of answer choices

True

False

2.

When a C++ programmer declares a function, they are required to state all of the following except

Group of answer choices

{}

The type of data, if any, returned by the function

The function name

The type of data, if any, sent to the function

3.

When a C++ programmer calls a function, she states all of the following except

Group of answer choices

{}

The actual run-time data values, if any, sent to the function

The function's name

The actual run-time data value, if any, returned to the function

4.

Supposed you want to write a function whose parameters are not modified by code executed in the function. That is, she wants the values from the calling's function to not be modified by the function being called. What kind of parameters should you use?

Group of answer choices

pass-by-value

pass-by-reference

pass-by-name parameters

array parameters

5.

Consider the following statements:

if ( i <= 5 ) {
        cout << "Hello ";
}
cout << "Goodbye";

based on the following variable declarations and initializations:

int i = 5;
int j = 2;
int k = 6;

When executed, the upper statements will print out:

Group of answer choices

Hello Goodbye

Hello

Goodbye

Nonthing will be printed

6.

Consider the following statements:

}

based on the following variable declarations and initializations:

int i = 5;
int j = 2;
int k = 6;

When executed, the upper statements will print out:

Group of answer choices

Hello

Goodbye

Hello Goodbye

Answer 1

Ans

1. False

No class doesn't have instance member of its type but it can have static member of its type

2.{}

function name, datatype of parameters and return type is required

But {} is used when defining a function

3.{}

on function call, function name, values pass to the function,

4. pass-by-value

pass by value doesn't modify actual parameters

pass by reference pass the address

pass by name pass function definition

array parameter passes by reference

5. Hello Goodbye

if condition gets true and it prints Hello

and then goodbye is printed

6. Hello

if condition gets true Hello is printed. Hence else block do not execute.
