Little doubts
-
i got some small doubts as i am new to c++. Will u please help me to sort it out? (1)is 'int* x' same as 'int *x' (2)'char const* x' same as ‘const char *x’ Vendy

1 - yes, whitespace is irrelevant 2 - no. one makes the pointer const, one makes it's contents const, from memory. They are not the same tho. Christian I have several lifelong friends that are New Yorkers but I have always gravitated toward the weirdo's. - Richard Stringer

(1)
int* xandint *xmean the same thing. (2)char const* xandconst char *xdo not mean the same thing.char const* xmay be read as 'x is a constant pointer to char'. In this case, the pointer is constant, not the character data it points to.const char *xmay be read as 'x is a pointer to characters that are constant.' For this one, the character data is constant.

thank you guys.... one more thing.. is 'char const*' same as 'char *const'??? Vendy

yes. const is only an identifier, but most use it before the type. you could verify it by yourself (and you will have too because even if you're new to VC++, this is not a "primary school forum") using
sizeof()... another thing : read this[^]

I think you got it wrong, char const * x and const char *x are the same and prevent you from changing the contents. For making the pointer itself const, you need to use char * const x. Regards Senthil _____________________________ My Blog | My Articles | WinMacro
