I was doing a C++ bitmap loader program when I found this ...
take attention on the variable pix ...
------------CODE----------------
#include statement ...
char *pix;

int main() {
//.......
loadBitmap();
}

int loadBitmap() {
//.......

pix = new char[...];
//load bitmap to pix..
}

----------------------------------

the code above wont display the bitmap ....
but if I declare
char* pix = new char[...] straight away on the global scope area ... it
will work ... why??... could anyone explain ..??
thanks in advance


Sid
