Making a program that makes a program?

hey guys, im back again :P, i was wondering if anyone could give me any leads on what to search for or research, so that i'm able to create a program that creates a program e.g. a console application that when executed, asks the user "select a feature to be in your program" then when the user picks a feature it will check the feature and make a .exe that does that function when executed. i asked a friend a while ago and he said to look up the dos and exe headers but i have no idea where to start. thanks in advance.

I think thats call a compiler :-) You tell it what features you want via text input(source files) then it spits out an .exe :-)

I think you could make a program that writes the code for another program. Then you could compile via command line and run.

Research compilers, if you want a general solution. But if you just want a few features, you could probably do a very system-dependant program that uses system() along with some macros.
