This is ultimately a matter of personal taste. It doesn’t matter to the compiler or your program either way.
If you’re working on a team with other programmers, the important thing is that you follow their established standards. If you’re maintaining a base of existing code, follow the style already established in the source. Otherwise, you’re free to make your own decisions about how to format your code.
Personally, I prefer the second style. It makes it much clearer to me what the types are of each variable. Additionally, if you’re working in C or C++ and declaring pointers, it’s important to keep in mind that
will only declare
ias a pointer to anint(see this question for more discussion). Using the second declaration style makes it completely unambiguous, which is always better for long-term maintainability. The amount you’re saving by squashing all variable declarations to one line doesn’t seem worth it to me.
