Your "scriptc++" is simply a Makefile after all ...

Create a 'run' target in your Makefile which depends on target 'all' (which 
builds everything as usual) and start the program in the action section.  
Now you can type 'make run' and the program will be build (if necassary) 
and started.

For various such "C++ scripts" you can use a pattern like this:
	alias prog1="(cd ~/scripts/prog1/; make run)"
	alias prog2="(cd ~/scripts/prog2/; make run)"
	...
Or:
	alias prog1="make -f ~/scripts/prog1/Makefile run"
	alias prog2="make -f ~/scripts/prog2/Makefile run"

Just an idea -- you have to work out the details ...

BTW: If you don't like compiling -- why don't you stay with Python?
