No problem, I understand and I hope I can learn through my errors. So far my program I think stores a temporary function at the start that converts any value of number entered into a double fahrenheit and returns it to another double celsius.
I stored that there just for formula's sake, and haven't implemented it or really know how to use it yet.
Then i think in this part I have correctly made an array of 50 doubles called myarray. Then i have made an int value flag that is in place of if the user puts a 1 or 0 to continue/stop the program. I want to be able to make an array that is assumed to be less than 50 values, and then the user to keep entering values until done, but I think I have it setup wrong is it just storing the values inputted into myarray[50] only? Do I have to seperatly do myarray[0], myarray[1], etc each time or is there some other loop i can make that can tell the program to keep entering values starting from [0] until when the user wants to stop. Then it should print out how many arrays there are rather than values in them. I just can't figure out how to stop the array and have the values only how many the user inputed, not all 50. Any help greatly appreciated thanks.

return fahrenheit;
};
int _tmain(int argc, _TCHAR* argv[])
{
double myarray[50];
int flag;
flag =1;
while (flag==1)
{
// loop
cout << "Enter Temperature Reading:";
cin >>myarray[50]
;cout << " Enter 1 to input more values, 0 to stop";
cin >>flag;
}
return 0;
}

You're going to the same spot each time. Use a variable here.

if i make another variable, say i.. and define it like
int i
i=0
(not sure if this is right)
for i=0, i<50, i++
{
// cout "Enter Temperatures";
cin >> myarray[i]
does that work better?

Probably, but you should surround your code snippet with <pre> tags and replace angle brackets with their non-translated version (see the buttons above the smileys).

ok thank you. If i do use this and user myarray[i] as the user input, will this put data into 0-49 of the array , or until the user wants to stop?

Yes.
Why not use one of the STL containers (e.g., vector, list) instead? That way, just enough room is allocated.

haven't covered that much so we didn't have it mentioned as part of the project. I will look into them and post if I have any problems, thanks.

That's fine. I found it better to know how to do it the "hard" way first. Then when I started using MFC (and some of STL), I understood it a lot better.

An AV error is usually the result of trying to access memory that is not valid. Given the address shown, I would guess that you had an invalid pointer (or reference if using DLLs w/VC6), or a pointer that was once valid but is no longer (like by double-freeing or trying to use an allocated resource that was previously released).
To debug it, crash it under the debugger to see what variable is being used that caused the crash, and then track its use to determine where it has gone bad. Some situations like buffer over-runs or under-runs can also cause problems like this, because you "step on" the value of a pointer/reference causing a crash when you try to use it.
Peace!

I found a program in C++ which uses this library, but my program doesnt recognize this library. Does someone knows other library to replace it?
|
|
|
|
|
I don't think the library exists any more. Try using that other one.

Look (real hard) at your initial post. How would you answer it?

Does it really support those features?

Actually the first version supported it, but in the later versions it's depricated.

It's no longer deprecated on Vista.

 , but Vista the whole would be depricated soon!

The initial library is called sys/time.h. I want to know the name of another library who can replace it.

That's available on Unix, but not Windows. Which functions from sys/time.h do you need?

Hi all,
I can easily change the color and bolding of text in a CRichEditCtrl using SetSelectionCharFormat:
CHARFORMAT cf;
::ZeroMemory(&cf, sizeof(cf));
cf.cbSize = sizeof(cf);
cf.dwMask = CFM_BOLD;
cf.dwEffects = CFE_BOLD;
m_text.SetSel(start, start + len);
m_text.SetSelectionCharFormat(cf);
BUT if 'start' is zero, that is, if the range I want to affect is right at the beginning of the control, then the whole text turns bold! Not just the 'len' number of characters!
This is really frustrating - what's so special about position zero that it wants to propagate its styles throughout the text? Is there a workaround?
Help!
Thanks!
~ Mike

why...when I implement this function in C++....it give me...
warning C4996: 'fopen' was declared deprecated
void printitems(allinfo *a)
{

itype x1, y1, z1;
FILE *trace;
stype vol;
char s[20];
vol = 0;
trace = fopen("trace.cont", "w");......}
