Answer the following questions true (T) or false (F)
1. There is only one kind of parameter passing in C++, namely call-by-value.
Explain.
2. The call-by-reference mechanism is specified in the function declaration and definition, using a $ between the type and the parameter.
1. False
Explanation: There is also call-by-reference. Call-by-value makes a copy of the argument then uses that, hence does not make changes to the argument. Call-by-reference effectively passes the argument hence can make changes to the argument.
2. False
Explanation: The character is an ampersand, &, not a $. It is placed between the type and the parameter to indicate a call-by-reference parameter.
