dev-cpp-users Mailing List for Dev-C++ (Page 3)

Why the following code does not work as it is supposed to work?


#include <stdio.h>

int main()
{

printf("This is a test\b\b\b\b\b\n");

return 0;
}

I expected to print on screen "This is a".

I tried it on 3 compilers with different combinations and the results were
the same ('\b' not erasing).

    Yes I see what you mean, I think the Microsoft people brought this =
on themselves; people shouldn't have to  download 5 megs worth of files =
just to get one 200k file that they really want.

Shameless plug: I've added 5 more tools from platform SDK they are:
    Stress.zip                       - similar to resource watcher =
(which comes with windows)
    Heap Walker.zip           - walk the heap : )
    ImagEdit.zip                  - kinda dumb image editor
    Heap Watcher.zip        - watch the heap : )
    Screen Capture.zip       - let's you capture your screen movments =
and saves it as an .avi

Hi all, When I put the function "include <conio.h>" And I compile the source
code, appears the following error message:
"ld: cannot open crt2.o: No such file or directory"

What can I do?

Please help me!

Thanks.

I am  having a problem printing also, but with the output.

using #include <fstream, putting ofstream pout ("PRN") in int main(), and
changing the cout's to pout's does absolutely nothing on my system.

hello, this is my first message.new to the group and program.

Im trying to print out the source files from my project.
but when I click on file|print from the toolbar, the appropriate messages
come up ,and when i finally say ok print,the file does'nt get printed.And
there are no error messages.Anyone seen this before or I have some kind of

  I'm having a trouble understanding how to do this assignment.

  We are supposed to send a character constant as areference parameter to
the function GetUserInput six times - to get Odometer

  A character constant: 'a'. As an argument to a function f() which accepts
a reference of a char. f('a').


   Start, Odometer End, Hours Start, Hours End, Minutes Start and Minutes
End.  The instructor said that I do not have to initialize (as in (//get
total mileage) StartReading, but to just send the string.  I don't
understand the syntax for doing this or how to use it in the output
statement.

  I am also confused about how to do the Average Speed function.  Since we
are required to convert the total time of the trip into minutes, someone
could travel a hundred miles in two hours, but then it would be 100/120
which doesn't make sense.  The function

  I did not understand it. I think your time is 120 minutes here.


   for turning minutes into hours and minutes also gets an error for using
ints.  However, we don't want a float for this since we have to output the
times in hour:minute format.


  Suppose you have traveled 169 minutes. 169/60 is the hours of the journet
and 169%60 is the rest of the minutes.
  So in this example:

  169/60=2 hours
  169%60= 49 minutes.

  Total time: 2 hours + 49 minutes.

Go to the command prompt window, cd in the directory you have the source

Hi,

I got around this by getting the newest library files from the latest

It works fine if you use {} instead of ()
Try this:

	int distribution[5] = {0};

You´ll get no error message.

Hello everybody,

Just a quick question regarding Dev-C++ (I'm using v3.9).

Has anybody encountered a good class builder utility?  Ideally something
along the lines of MSVC++ v5.  Nothing super special, just something to
generate standard C++ classes (most preferably with a Windows interface).

Thanks,

-----

You could also replace the {0,0,0,0,0} with {0} (if I recall properly, this
works with all ANSI C/C++ compilers).

Try this int distrubution[]={0,0,0,0,0}
 
It means an array of ints ,with proper size (5), initialized with all
elements to 0.
 		
	zsombi

to initialize an array you do this :

int distribution [5] = { 1,2,3,4,5 }

I am new at C++, but i think that your initialisation is somehow wrong.


Ioannis

Probably the compiler's fault. Why don't you try creating a function that
handles that ?
E.g. :

template <class ARRAY_TYPE>
void fill_array ( ARRAY_TYPE [] &arrary, int number_of_items, ARRAY_TYPE
fill_value = 0 )
                        { for ( int i=0; i < number_of_items; i++ )
 array[i] = fill_value; } }

I know you said you didn't want the for thing... but making it a function
becomes really easy to use :

fill_array ( distribution, 5, 0 );

Byezzz

Why do I get an "invalid initializer" message for the following line in my 
program?

	int distribution[5] = (0);

It seems the only thing that works to initialize an array is a "for" 
statement.  Does anyone have an answer?  The above line is by the book and 
should work.  Or is this a software bug?  Some how I doubt that.
