type cast


Hi... whats the easiest way for converting an integer, double e.tc to a string?
Do u have some good articles for type casting?

I have written a simple function for writing things to a file... the problem is that the function take only two arguments a string to write in the file and the file path of the file... After using my function i have noticed that isnt so easy to store integers and results from other functions so i need your help to modify my function...
Any good suggestions?
Thxx a lot

Type casting and converting numbers to strings are unrelated. Check out this site for what you are looking for:
http://www.cplusplus.com/ref/cstdlib/index.html

These work for C and C++, but in C++ you need to #include cstdlib instead of stdlib.h. Also, some C++ compilers put some/all/none of these functions in namespace std, so watch out for that.

As far as casting, in C all you need to do is put the type to be casted to in parens:
int Num = (int) 'a';

That is frowned upon in C++, however. Take a look here for casting in C++:
http://www.cplusplus.com/doc/tutorial/tut5-4.html

The C-cast is equivalent to reinterpret_cast when used in C++, and can be dangerous when dealing with classes. It does serve useful for turning objects into raw data however (unsigned char).
