Type Declaration - Pointer Asterisk Position

Question

in C++, the following means \"allocate memory for an int pointer\":

int* number;

So, the asterisk is part of the variable type; without it,

Answer 1

Actually the asterisk is attached to the variable (a convention inherited from C), so

int * number1, number2;

declares number1 as a pointer to int (i.e. *number1 is an int), and number2 as an int.

The spacing has no effect on how the number's are typed. It just serves as a token separator. All of the following are the same to compiler, because the spaces will be stripped after parsing.

int *a;
int*a;
int* a;
int * a;
int/**a***/*/*a***/a;

Use

int* number1, *number2;

to create two pointers, or even better, split it into multiple declarations to avoid confusion.

int* number1;
int* number2;
