Question

I know you can print an array in gdb , e.g.

(gdb) p *array@10

Is there a gdb command that can tell you its length, e.g. a handy shortcut to typing something like:

(gdb) p sizeof(array)/sizeof(int)

In the case where the array has been defined at compile time and you want to check it

Answer 1

You may use ptype to know the type of a symbol.

For int array[5],

(gdb) ptype array
type = int [5]
