This is certainly false for Ada:

In particular, the standard package Interfaces.C.Pointers overloads the 
"+" and "-" operators for just this purpose.

It is arguably false for many widely used flavors of Pascal including 
Object Pascal and Turbo Pascal.

Even Fortran has a non-standard extension for this:
