No, most likely not. You don't seem to understand how memory is allocated by modern operating systems - normally, no process (=program, for our purposes) is allowed to read the memory section of any other program, unless the other program explicitly opens up some memory to be read by other programs. So even if you start another program as a subprogram, you are unlikely to be allowed by your OS to read it. Also, at least with reasonably modern operating systems, memory addresses should be reused and should be local to every process, but I think that at least on the x86 platform, all 32-bit operating systems hand out a shared address space to all processes (but still with read/write protection).
If the program has stopped running already (like your C program after it prints the memory address), the memory of the program will be overwritten by other programs as the operating system gives the memory to other programs.
In any case, Perl is most likely not the tool you want to be using, whatever you want to do.
