Is 'const int' same as 'static const int' ? : c++

Is 'const int' same as 'static const int' ?
These variables are declared inside a class.

Nope.

By "inside a class" I hope you meant inside the scope of a declaration of a class. Assuming that's what you meant...

In such a context, static declares that there will be only 1 such class-wide data member; as opposed to there being 1 per-instance (inside every object of the class). The const declares that this variable will receive a value only during its construction.

Inside a member function of a class (or for that matter, any function), static means that it's non-automatic; that is, that its value survives returning from the function (also that it can have a value prior to ever entering it, too). It also means that multiple threads of execution through such a routine can contend over access to the variable.

Even outside the body of a function, static const int is not necessarily the same as const int. At the compiler's discretion, a simple const declaration doesn't necessarily reserve a storage location; it's just a symbolic literal declaration similar to a #define manifest constant, except that it now has an actual hard type, and that it can't be #undef'd later on. In contrast, static const int definitely reserves an actual storage location that's private to that compilation unit (and you'll have to initialize it, because you can't later on - it's const, right?). Note that in the latter case, const is used as a modifer - not a declarator: we're declaring a variable that cannot be modified, whereas earlier, we were declaring a symbolic constant.

Sadly (and by now obviously), static and const are both over-used keywords in C and C++; their precise meaning depends on where its used. Crack the books, I suggest. Hope this helped some.
