Is int* number_1 same as int *number_1?

Question

I am little confused about how pointers are/or can be used. for example:

int addtwonumbersfunction(int* number_1, int* number_2)

Is it same as: int addtwonumbersfunction(int *number_1, int *number_2)?

Does it matter where * is placed? after int, or before variable?

You can write it without spaces or with as many spaces as you want. — Don Reba, Oct 03 '15 at 16:54

No it does not matter. Your two examples are semantically the same.

It doesn't matter, you can write both. int is the main type, so on multiple variable declaration, you'd have to add * everytime. Some prefer int* var because of grouping type & variable name, others like int *var because of the behaviour i described with multiple declaration.

Visually binding the `*` complicates maintenance due to how humans recognise patterns. – too honest for this site Oct 03 '15 at 17:05
