Help with some simple C++ questions
Hello, I'm currently reviewing for my first computer science exam and one of our study guides has some fill-in and true/false questions that I wanted to make sure I was answering correctly. Most of them I was able to put down what I believe is the answer, but a couple I had no idea. Could someone take a look and let me know how I did? Thank you very much.
A __________________ data type should be used to hold “whole” numbers?
int
Legal Identifiers/variable names can start with ____________________ or ______________________ .
underscore, letter
A __________ return type indicates that the function does not return a value.
void
A "Pass by Value" parameter passes a __________ of the value to a function and a "Pass by
Reference" parameter passes a_____________ of the value to a function.
? ? I do not know these ones
What operator returns the reminder of an integer math operation? ___________________________
Modulus / %
A return type of _________ indicates that a function does not return a value.
void
Having two functions with the same name, but different parameter lists is called ________
overload
The __________ and _______ loops will not iterate at all if their test expressions are false.
for and while
To access the value in memory pointed to by a pointer variable, you must use ___________ operator.
?
___________ is used to signify that a pointer doesn't point to anything.
?
Sample True/False Questions:
True/False: The instructions in a while loop are executed at least once.
False
True/False: An infinite loop can be caused by using a loop termination expression that is always true
True
True/False: You have to declare every variable in C++?
True
True/False: C++ is a case insensitive language.
False
True/False: A for loop always executes once.
False
True/False: It is illegal to use an assignment = as the input to a conditional (i.e. if):
True
True/False: You can change the value of a variable declared using the const keyword.
