How to convert C++ to C??

help me please

[deceptikon]

That's an old dialect of C++ and doesn't use any difficult to convert features. You need to do three things:

1. Change cin to scanf function calls.
2. Change cout to printf function calls.

3. Add a typedef to your structure so that the struct keyord isn't required:

   typedef struct mahasiswa
   {
   int nbi;
   char nama[50];
   char alamat[50];
   int telp;
   } mahasiswa;
   

For #3, as an alternative you can add the struct keyword to every declaration of the type:

struct mahasiswa data[3];

[jursnamo]

how about

clrscr();

?

[deceptikon]

Provided your compiler supports the non-standard conio library, it'll work between C and C++.

[jursnamo]

no, I want to try convert C++ to C

[deceptikon]

It's a C library, but also works for C++.

Or you could just write your own clrscr() function, it's not all that difficult, just a one line function.
