You have to turn terminal local echo off. This is often specific to what kind of terminal you are using. Are you using the windows command prompt?

Trace the execution of your code.


// here let's say that hours = 23
calculate(hours, minutes);
void calculate(int& h, double& m)
...
if(h>12 && h<=24)
{
h=h-12; // Now...

I don't quite understand what you are asking. If you could clarify, I can give you a better answer. There is an excellent tutorial on opening and reading/writting files here...

Also I didn't notice this at first:

What you really want is so that if you check every item and it equals '==', then you return true. If you ever see a mismatch, you dump a false.



bool...

Here is your problem. You are assigning p[i] to c[i]; basically copying the values from one array 'p' into array 'c'.
if( c[i]= p[i])


What you really want to be doing is the '==' equals to...

char c='A';
char *p;
p=&c // <-- should read a pointer (*) to char named p gets the the address (&) of char c

char var1, *ptr1; // <--- * goes here
var1='X';
ptr1=&var1;


It's important to remember that you need '*' for each pointer variable. Therefore: char* ptr1, ptr2; doesn't work as intended....

There is no right order. You might even want to play with all of the above and see which one you like the most. Learn that language well, then move on to another. The languages aren't that...

New Project?

Please put the code in [ code ] [ / code] tags... it'll be easier to read.

Where is the error about null ofstream happening?

Here?

Have you tried programming with Java and Eclipse's SWT? SWT GUI apps are actually quite comparable to native C++ programs. Java doesn't have to be slow, ugly, or a resource hog.

About the original topic: Languages are long lived and possibly immortal beings. There will always be C++ somewhere. Don't forget our Y2K fears about that ancient dino Cobol.

If this is truly a C++ test, why the focus on so much C style code?

Ah... It all makes sense now. I never did have much faith in certification programs. Best certification is demonstrated project experience. :-)

Ok... I still have the stomach to answer your question. This time at least it's a different mistake ;-)

#define's can only be multilined if you do the \
at the end of the line


#define...

Chainsaw your code is good. I think you are a fine engineer in the field.

I meant Mr. C++'s code is wrong. He uses * and & with no idea what those operators mean. I've explained it to him more...

Hi the_one2003a,

What's the point of pointing to an enumerated constant? I think the key is that an enum is really a constant. An enum statement 'enum Date {mainX=1,mainY}' is almost like one is...

No. Your code is wrong. I thought I taught you how pointers and dereferencing work. *sigh* I guess I won't lose my cool over your fishing for answers. Do heed our advice; All these questions...

You seem to have two questions on your mind.

1) How do I have a member function length?
class String {

char* fString;
public:
// constructors
String();
String(const char*);

There is a reasonably high learning curve for both DirectX and OpenGL for game programming.

Have you programmed GUIs before? If you haven't I'd recommend you start out with glut and OpenGL. I...

Hi C++,

You cannot use a char* pointer for which you have not allocated space. char* support contains a junk value unless you do a) or b).

You can either
a) not use a pointer. do char[255]...

What is it you wish to accomplish by learning these frameworks?

pCat->Pointer says give me the member variable of the pCat instance object. pCat->Pointer is type int*. So we can do this *(pCat->Pointer) to get at the value.

Because of operator precedence...

Hi there,

I think you better reread my post and think over the problems before asking for help. Right off I see that question #1 you should be able to fully solve yourself. I answered that...

Hey Mr. C++,

You just got the semantics wrong. Remember that it is always something like this:

Always pointer to int = the address of a variable.

int variable;
int *pointer_to_int =...

Uhh.. I clearly see that tleds has source code on their website. Check again. At any rate, you may do an exec C function to call the program setleds. This will also work.

Ed

Actually you can do this programatically fairly easily...
Using Windows API's SystemParametersInfo with SPI_SETDESKWALLPAPER.

Try using setleds. It comes standard on most linux boxes.
