To avoid buffer overflow, prefer using cin.getline(char_ptr, size);

>> With that code, calling the >> operator will always store it into appt.subject, but what about storing information to...

The problem is again sort of same. appt.subject = new char[strlen(ptr) + 1];. Neither ptr holds any string nor it point to any dynamically allocated memory and you are still trying to calculate its...

Its happening because subject is not pointing to a valid address, basically you haven't allocated memory to it. Either use char subject[size] or allocate memory in constructor using malloc() or new...

The given code snippet checks whether a given string is a part of other string and wildcard are allowed.

Oops...I just missed a point in previous post. Anyway the loop gotta look like this.


//take matrices values before starting
for (int i=0; i<6; i++)
{
for (int j=0; j<6; j++)
{
...

First of all replace M[i][j] = m1[i][k]*m2[k][j]; with M[i][j] += m1[i][k]*m2[k][j];. See the algorithm in above post, for explanation. Also dont forget to set M[i][j] value to 0 before running third...

What you have done is multiply corresponding elements of matrices. However its not so. First of all the two matrices should not be necessarily of same dimensions. It should be rather of form NxP and...

Use you command promt and run. Or if you want to run it directly add std::cin.get() at the end of main() to wait for a keystroke. However this wont work under certain circumstances as mentioned here...

This is typecasting (http://www.cplusplus.com/doc/tutorial/typecasting.html), i.e. changing a data from one type to another. Both are same and works same. Enumerators are nothing but named integer...

What linker errors are you getting? You have just declared the function paidout() but not defined it. And perhaps you have called it somewhere else. Also if you think thats the whole program then its...

> everybody runs to get the latest copy for no reason
Someone wants latest version not for intellisense, but for updated compiler with bugs fixed, compatible with latest standards etc.

And I see...

Borland apart for C++ Compiler 5.5 also distributes a free IDE called Turbo Explorer C++. You can get that at www.turboexplorer.com.

Yes windows.h, if you are using windows. And the function name is Sleep() not sleep()

No, back() return reference.

I think you are talking about CBSE 12th class project. I'm too 12th class student and writing my project myself and I advise you to write yours yourself only or you will be in GREAT trouble. The...

Take number as string. Also long int, long long etc etc may take number till 10 digits.

Tutbo C++ 3 is very old compiler. You should move to modern ANSI compilers ( not if your teacher asks you to use it :), no other choice left).

Well to use mouse in Turbo C++ 3 you will use dos.h....

Ok got it. I reckon standard function in ctype, would be the best practice. But, is there any way to implement a portable function for this??

The program you are discussing is a Windows program which uses Win32 API library.

In resource.h you may get error if you havn't left a blank line at the end.

If you dont know what hInstance or...

You may use getline() . Here's tutorial (http://www.cplusplus.com/doc/tutorial/files.html)on file i/o. Read and try yourself, if you encounter any problem you can post here.

> Your program is wrong. iostream.h is not a valid c++ header file, IOSTREAM is.
Right, but maybe his teacher expects him to use old compilers like Turbo C++, like my syllabus and teacher :)

If getnumber() doen't ask for values but just shows them, it would look like this


int findbig(int a, int b)
{
// will return -1, if a is greater
// 0 if both are equal
// 1 if b...

You could add a simple infinite loop for that, and set a condition that if input character is something other than lower case it would break:


while( 1 ) {
cin >> b;
if( (b < 'a') ||...

Well, simplest way for that you could create another integer called sum. Then you may create a loop and each time ask for input, place a condition to terminate:

while( (choice != 'N') && (choice...

Maybe this (http://www.daniweb.com/forums/announcement8-2.html)and this (http://www.daniweb.com/forums/faq.php?faq=daniweb_policies)would help you.

A little google search gave me this (http://msdn2.microsoft.com/en-us/library/bb248591.aspx). This would require ATL.

Which version of djgpp are you using. If it is prior to 2.04 it wont work. Read it here (http://www.delorie.com/djgpp/doc/kb/kb_6.html). Try using Sleep() function.

Write everything on paper i.e. problems and solution that you guess, write algorithm and flowchart before you start coding. This will show you way.

These are Windows specific functionis related to INI files which are Windows Configuration files, so there couldn't be any standard function.

If you mean copying through C++, then Ancient Dragon has given nice piece of advice otherwise if you mean copying later like a normal guy.

Then there is no relationship between DOC files and HTML...

a) Absolute temperature in Celsius is -273C. Convert it to Fahrenheit and put an if condition wafter taking input.

b) To give output into this form try this:

By, DOC I suppose you mean document file(MS Word). To generate that kind of file you will need some library. I dont know if there is any free available but you could look into OpenOffice source code...

I think there is no way in Standard C++. You will have to use your OS API.
In old non standard compilers there used to be stdprn stream for windows and DOS, but now no longer supported(and ofcourse...

I would refer book C++ Programming Language by Bjarne Stroustrup. Or you could google and get several links.
