document yourself about linked lists. they can be performed using C structures, and a set of pointers...
otherwise, you have to allocate/reallocate/free blocks of memory as you need...
|
|
|
|
|
You can use pointers if you know that.
|
|
|
|
|
Ask user approx how many char(s) his string will be. the allocate memory to a char pointer with the size specified.
char * str;
str = (char *)malloc(size);
|
|
|
|
|
Can we do it without asking the user??? Is any other Way?
|
|
|
|
|
uhhh, where is the user asked ? your program allocates memory without asking AFAIK !

char str[100]
i dont want it this way ..i want that all the characters which a user give i/p can be allocated memory...that means we dont know yhe exact array size

Do you get them blockwise or char by char?
For blocks, a linked list of blocksized buffers would be the way to go.
For single chars, you could assemble blocks by yourself (get chars until you have, say, 512 and then add this buffer to your linked list and make a new buffer of size 512).
Note that there must be any amount of ready-made solutions for that on *specialized C-Programming pages*. Not in the C++/MFC forum of Codeproject.

Yes. Assign each character that the user types to a char variable. Dynamically grow an array and append the char to it each time. Note that this reeks of inefficiency.
Why don't you tell us what you are ultimately trying to achieve so that we may possibly offer a better solution?

I am trying to debug a program in release build.
But after some time i getting a message like
"User breakpoint called from code at 0x77f813b1"
how to rectify this one?
What actually is the problem here?
Please help me.............

have you set a breakpoint somewhere ?
have you tried to step into the debugger and watch your variables to understand why it was crashing ?
BTW, what's your IDE ?
|
|
|
|
|
No, I removed all the breakpoints in my program.
Actully i am using Visual studio 6.0...

I come across this misconception all the time; there is no truth to it. There is nothing to stop you from enabling debug information for release builds. I do it all the time. The only issue is the MSVC IDEs don’t do this by default. If I made it they would.
