string::capacity()

[tcsvikr]

Hi,
The string::capacit y() returns the size of the allocated space, which is either equal or greater than this content size.
My question is: Is capacity assigning equal or greater than content size compiler dependent??
I've used the same function in a sample C++ program and compiled it with g++ compiler(linux) . The result is always equal to the content size but never greater.
can some one help me in clarifying this.

The string functions change according to the compiler as the implementation changes compiler to compiler.

Hi Raghu!!
Thanks for the reply.. I've observed the same in VC++ ..The implementation is different from linux

That is OK, as long as the string has enough memory for it's current contents then it is conforming to the standard.

There are several ways to implement a conforming String class and you may well find that different platforms exhibit different behaviour. That is why it is important to learn to write code that conforms to the standard and does not rely on the special behaviour of any one platform, especially if you intend the code to compile across different platforms.
