C doesn't have a String data type, unless that supposed to be a typedef for something.

Having said that, I think this is taking advantage of the fact that array indexing in C is commutative; IOW, "a[i]" and "i[a]" both evaluate to the ith element of the array a. If "showdata" returns an integral type, it can be used to index into the array expression "hello".

Ive attached a quick-n-dirty example that illustrates this.

Code
#include <stdio.h>


"%c


", foo()["Hello""%c


", "Hello"
