Unable to compile #include "mbed.h"

I'm trying to create a new file for an LPC1768 program but when compiled results in many errors, e.g.,

Error: Identifier "namespace" is undefined in "extras/mbed_dc225afb6914/DigitalIn.h", Line: 23, Col: 2 Error: Expected a ";" in "extras/mbed_dc225afb6914/DigitalIn.h", Line: 23, Col: 16 Warning: Parsing restarts here after previous syntax error in "extras/mbed_dc225afb6914/DigitalIn.h", Line: 85, Col: 16

etc.

I've commented everything in the file except the #include "mbed.h" statement and the errors are still generated. The program would compile before I added the new file.

What might be wrong here?

I have a similar error and no idea to solve it. Filename is cpp.

Error: Identifier "namespace" is undefined in "extras/mbed_8a40adfe8776/DigitalIn.h", Line: 23, Col: 2

    epaper.cls();
    epaper.set_font((unsigned char*) Arial28x28);  // select the font
    epaper.locate(5,20);
    epaper.printf("Hello Mbed");
    epaper.rect(3,15,150,50,1);
     
    epaper.set_font((unsigned char*) Arial12x12);
    epaper.locate(5,60);
    epaper.printf("small Font");
    epaper.set_font((unsigned char*) Neu42x35);
    epaper.locate(5,70);
    epaper.printf("big Font");
    
    epaper.write_disp(); // update screen
    
    wait(5);
    epaper.fillcircle(180,30,22,1);
    epaper.circle(160,150,20,1);
    epaper.write_disp(); // update screen
   
}

I found the problem, the filename extension was "c" instead of "cpp".
