Define a class

thoret — Wed, 21 Dec 2016 18:20:04 GMT

I try to write a simply programm and I want to define a class linke:

class myclass{

...

};

Directly I get an syntax error.

After I bulid the project I get an error:

Multiple markers at this line
   - Syntax error
   - unknown type name 'myclass'
   - expected '=', ',', ';', 'asm' or '__attribute__' before
   '{' token

I try to write it in a .h file and a .c

I work with LPCxpresso 8.2.2_650

I try to implemented math.h but the error still exist.

I think he dosn't know "class" but why? It is C syntax, isn't it?

Class is C++ and not C. In lpcxpresso you need to creat a C++ project and .cpp file for your code.

Hi Thore T,

Fall Guy is correct, Class is the data type for C++, not for C, so if you want to use the class type, please create a C++ source file instead of C file.

Wish it helps you!

If you still have question, please contact me!

Have a great day,
Kerry
