Differences between struct in C and C++

Question

I am trying to convert a C++ struct to C but keep getting "undeclared identifier"? Does C++ have a different syntax for referring to structs?

struc         


        

Answer 1

You could/should typedef the struct so that you don't need the struct keyword every time you will declare a variable of that type.

typedef struct _KEY_STATE 
{
    bool kSHIFT; //if the shift key is pressed 
    bool kCAPSLOCK; //if the caps lock key is pressed down
    bool kCTRL; //if the control key is pressed down
    bool kALT; //if the alt key is pressed down
} KEY_STATE;

Now you can do:

KEY_STATE kState;

or (as in the example you have) :

struct KEY_STATE kState;
