You probably meant: since c_info is an array, by doing c_info[i] you’ll access the i-th instance (object) of Employee class in c_info array, and then obtain hoursWorked through . operator. Now you can clearly see that your variant simply doesn’t make sense, as hoursWorked is just an integral type and not an array, and therefore … Read more
If you include Item.h from your cpp file, Player.h is included from it. Then, Player.h includes Item.h again, but thanks to the include guard, this does virtually nothing. Then, in the included Player.h, no Item is declared yet. Therefore, the compiler will emit the error. Since nothing from Player.h is used in Item.h, remove #include … Read more
First, it usually does not matter that much in practice. Most hash functions are “good enough”. But if you really care, you should know that it is a research subject by itself. There are thousand of papers about that. You can still get a PhD today by studying & designing hashing algorithms. Your second hash … Read more
I am currently trying to learn C++ and following an instruction. I’ve researched on mutators and accessors but I need a simple explanation. Right the code above is in a header file. Within the instructions it is asking me to set a public accessors and mutator for both data. How do I do this? Also … Read more
or The second variant is a more generically applicable solution, as b could also be an array. However, it requires C++11. If you want to work with user-defined types, use ADL:
There’s no need to use a function. To find the median of a list with an odd number of items, just do where sortedArray is the array and size is the size of the array. For an array with an even number, you should just do something like this In other words, take the average … Read more
Because you can’t assign to arrays — they’re not modifiable l-values. Use strcpy: And you’re also writing off the end of your array, as Kedar already pointed out.
Isn’t this the normal way to free the memory associated with an object? This is a common way of managing dynamically allocated memory, but it’s not a good way to do so. This sort of code is brittle because it is not exception-safe: if an exception is thrown between when you create the object and … Read more
How about this :-
Your code has undefined behaviour because you are trying to assign l from an uninitialised array str. I’m guessing you got your functions confused and meant to write the opposite That code assigns l to str. Use the following code to work out how big str needs to be
