You are confused. The null (\0) character doesn't get put there magically by the compiler. If you want to be able to treat that char array as a string, YOU have to allow space for the null...

Your printing problem is not because there's anything wrong with the arrays. It's because of the way you are printing.

So I guess that's a "yes" to your last question.

Sorry, I wasn't paying attention to the rest of the constructor. The problem there is that if you give a char array to cout, it will print everything starting at the beginning of the array and...

I think you will have to show how you are outputting the arrays for anyone to tell what is going wrong with that.

Also, have another look at this:for(int alter = 0; alter < 26; alter++)
{...

It would be much easier & make more sense to define
struct student{
int age;
string name;
} outside of any class. Then you can instantiate a student in any class that needs to have one, and use...

PS: multiple program files are not input/output files. When your program is in a single file you don't "call" that file in the program, do you? Well, in a multi-file program you don't "call" these...

I've already told you twice, but you don't want to believe me. I'll try again: You don't call the cashier file. You simply call the function cashiermenu(), or whatever it's called, exactly the same...

You shouldn't have to write anything differently. You just include the header file for the function you want to call in the implementation file of the calling function. The calling function (let's...

Are you planning on having your program write something to a file with that name? (I don't think so.)

A multi-file program doesn't involve anything like opening up other source code files while...

The correct syntax for calling a method of an instance of a class is:
objectName.method(args)

In your case:
cout << "Currently on the list are: " << mylist.display() << endl;

That may or may...

As far as largest_prime_factor() is concerned, a few observations:

- largest_prime_factor() returns a value, but your main() ignores the return value. If you want to use the return value, main...

Try running it with

Did you read this:

That's easy - squared-digit-length() isn't returning anything because you removed the return statement. And even if you restore the return statement, sometimes it won't return because, depending on...

I didn't try compiling/running it, but it seems to me that it might take a long time to get out the first call to squared_digit_length() unless num1 equals 2, and that won't happen unless the user's...

Did you add xxx.cpp to the project? I see nothing in the code you posted that should cause your problem, but the code you are posting is just uncompilable snippets. You need to post some simple,...

In xxx.h and xxx.cpp you have ExecuteBCombine, in main you have ExecuteBinaryCombinations, and yet the error message refers to ExecuteBCombine referenced from main? Is there a discrepancy like this...

In the above code, there are two completely distinct and unrelated variables both named b_setting. The first one declares a variable of type char* that is defined elsewhere -- in this case in...

See comments below:


//main.cpp
#include "xxx.h";

char b_selection [100]="";
void main(){
ExecuteBCombine (b_selection); }

Sorry, I was wrong about <stdio.h>.
#include <errno.h> should get it -- somewhere down the chain of includes.


errno.h includes bits/errno.h includes linux/errno.h includes asm/errno.h includes...

Did you #include <stdio.h>?

There's no bool type and no true and false constants in standard C before C99 (and in C99 you must #include <stdbool.h>) I don't know about Visual C.

You can typedef enum { false, true } bool.

remove the semicolon from the end of this line

else (*type == 'C' || *type == 'c');

Here's how it works: It enters the first while loop, reads the first line, stores it in the "line" array, then makes x=1, then it does "nothing" because of theif( x == 1 )

Yes, you said that already, but it still makes no sense to me for that to be in the input file. Surely, the program doesn't need that to figure out which data is in which column of the file. A file...

There are many ways to do this. Probably getc or fgetc would be the simplest for you. Look at a reference for stdio.h functions, for example this one, to see how to use those functions:...

You say C++ but you seem to be using C, as you #include <stdio.h> and use printf for printing. So, assuming you are using a C compiler, you should also #include <math.h> at the top of your program,...

You want to apply one value using the F_PROFILE function to points on your line, and another value using that function "everyplace else", but in C you must define points in terms of discrete values...

Perhaps you intended a test for equality (==), rather than assigment (=). And why the unnecessarily confusing multiplication by -1 in the first expression and double negative in the second?

Is this supposed to be C++ or is it some other language?

OK, when I posted last night I didn't realize that that you were talking about a graph with cycles, since you were calling it a tree with a root, parents and children (by definition, trees don't have...

Well, maybe I'm too tired to think this all the way through, but it seems like the children can have children which have children ... so your del would have to recurse all the way down through the...

All of that is true, but it is also very non-trivial for a beginning programmer to write portable code to clear any kind of screen on any kind of computer.

Good point. When you put calls to menu() inside menu(), you are inadvertently making unnecessary recursive calls to the menu() function, meaning you will be loading multiple copies of the function...

That's because you are never actually calling the function addEnd (even though you think that you are), because you still haven't fixed the errors that I pointed out in post #2.

Your code still...

Notice this statement near the beginning of menu(): if(select = 1)

As soon as your program gets to that point it assigns 1 to select, instead of testing to see if select equals 1. This overrides...

Well, you already know that you're concatenating in the wrong order so you don't need any suggestions regarding that (just fix it), so here are a few other things to think about:
