yeah, which makes it better for certain things like writing operating systems and maybe web servers. but C++ brings a lot to the table, like much more object oriented programming (eg, classes, inheritance...), better i/o, stronger type checking, no built-in buffer overflow vulnerabilities, etc. just the presence of classes makes C++ a way more desirable language for writing applications.

C++ also beats C in terms of ease of coding, which does mean a lot if you program all day long for a living.

 

I can so do that conversion in COBOL. h:

Comments are your friend.

 

This is probably way too late but try this, when you open your files:

a.open("groupA.txt", ios::app);
b.open("groupB.txt", ios::app);

This just sets the behavior to append to the end of the file rather than replace the contents.
