[Dev-C++] C and C++ sintax restrictions in Dev-C++

[<and...@su...>]

Dear Users,

--->	Some students are using a mix of commands and features like:
	/* 		and 	//
	getchar() 	and 	cin.get()
	<stdio.h> 	and	<iostream>
	<stdlib.h>	and 	<cstdlib>
	printf	and 	cout
	scanf		and	cin
	.c		and 	.cpp

"A"---> 	I´ve tried some enable/disabe options inside
		"Options->Compiler Options->C/C++ Compiler", but couldn´t
      	inhibt the students to write codes mixing the commands.
 		The corrections are still by hand. Sometimes is difficult
		to explain for some guys that come with vicious what a C or
		a C++ program is.

--->		My Questions:
1)	Is my attempt to convince them correct?
2)	If it is, is there any set of options that allows me to inhibt to mix
	C and C++ features?

Regards
Andre
