Build is not the same thing as run. Build rebuilds the program from scratch. This means: 1. Each source file (you may have more than one) is...
Unfortunately, your code will trash the heap. You only malloc'ed one char. Scanf will return anything entered BUT the newline. Malloc for a...
Yes, that's a good answer. You got the same answer here. It seems likely that you are going to pay no attention to either of them. You might...
Not only should main [] be main (), main should be declared to return an int. C++ does not support main as a void type, nor does it support an...
Google will give you a better answer to that question.
First of all, if you can't hack a little criticism, you're getting into the wrong business. If you refuse to think, you're definitely getting...
You're code is incomplete. It means nothing. There is no such thing as a 'dangling' pointer, despite all the protestations of various gurus that...
Pay attention. "ptr" was destroyed. Before it was destroyed, its contents were transerred out of the function, via the return mechanism, to...
"ptr" goes away, yes. It isn't a dangling pointer, it's a NONEXISTENT pointer. However, you RETURNED it's value to the calling code, so that...
Sure. Use malloc. One presumes this is C, not C++.
Malloc only returns a NULL pointer if it fails. Otherwise, in C (not C++), it returns a void pointer which needs to be cast.
It doesn't have to crash. It can trash the latest autovariable which is now using that memory, which can be a very subtle failure. Read up on...
If you don't know any programming language at all, I'd suggest that you start with something other than assembly language. You need to know how...
The bracket format is NOT used by printf. Where would be the utility of such a thing? Please try to avoid disseminating bogus information.
Wrecker, that is not correct. In your code, p is a pointer to an integer pointer. Dereferencing it will provide a value that is expected to be a...
The square brackets are a special form of the 's' specifier. They are similar to square brackets used in a regex expression. They define a class...
The C99 standard allows for run-time assignment of array dimensions, but few compilers are compliant in that respect. Consequently, we fake it....
We don't know how your project is set up, but probably not like that. Put your .h file in the same directory as your source file and include it...
I would vote, "Boggles the Mind", but I don't see that as a choice.
The ENTER key is not a space, but it is a character, therefore the default path in the switch is taken and the program exits.
Separate names with a comma.
