The following are three questions on a practice examination for Computer Science 102. I need help not only getting the answer but i need careful explanations and work shown for each of the three problems because some of these are "trick" questions:

16) double a = 5/2; both 5 and 2 are integers. so, 5/2 performs an integer division. so, 5/2 is 2 so, cout << a; prints 2 Answer: 2 23) if(a = 7) -> here = is not an comparison operator. it is an assignment operator. so, what ever the input is a=7 always returns a non-zero values. hence yes is printed, regardless of the input Answer: yes and yes 24) there is no break statement after case false. so, when case false is executed, it's next case(case true) is also executed. so, if i=false, answer is AB and if i=true, then answer is B

Help with C++ reverse program with leading zeros. I need to put the line from the function that display the zeros in main not in the function. So how can I move the display with leading zeros in main. Thanks. Here is my code. #include <iostream> #include <cstdlib> #include <iostream> using std::cout; using std::cin; using std::endl; //function templates int reverseNum(int); int main() { //variables char buf[100]; int num; while (true) { //prompt user for input cout << "Enter the number...

You are given a Q1.h file with overloaded function prototypes
for isOrdered. Implement this overloaded function into a file named
Q1.cpp. Q1.cpp should only include your function implementation,
the necessary #include directives if needed, and should not contain
anything else such as the main function or global variable
declarations. Test your code using a separate main.cpp file where
you implement a sufficient number of test cases. You should use
Q1.h as a header file and Q1main.cpp as a main function...

I need help in my C++ code regarding outputting the enums in string chars. I created a switch statement for the enums in order to output words instead of their respective enumerated values, but an error came up regarding a "cout" operator on my "Type of Item" line in my ranged-based for loop near the bottom of the code. I tried casting "i.type" to both "i.GroceryItem::Section::type" and "i.Section::type", but neither worked. Simply put, if a user inputs 1 as their...
