Thread: constant structure array - hlep please

I've got a constant structure array that represents a song, i declare another const struct of the same type and make this constant structure array = the other one, what is the correct code

Code:

//**************************
typedef struct 
{
  int note;
  int beats;
}Note_Beats;
//**************************



//***********************************************
//***************Song list***********************
//***********************************************

//********When The Saints Go Marching In*********
#define NumberOfBeats_Saints 16
const Note_Beats Saints[NumberOfBeats_Saints] = { {C6, 1}, {E6, 1}, {F6, 1}, {G6, 5},      {C6, 1}, {E6, 1}, {F6, 1}, {G6, 5},       {C6, 1}, {E6, 1}, {F6, 1}, {G6, 2}, {E6, 2}, {C6, 2}, {E6, 2}, {D6, 5} };
//***********************************************  
  
//**************Choose Song Here*****************
#define NumberOfBeats  NumberOfBeats_Saints
const Note_Beats Song = Saints;
//***********************************************

I am getting the error where I decalare "Song" and make it = "Saints"
ie at this code:

Code:

const Note_Beats Song = Saints;

When Song is pushed onto the stack, it's set to be const. Then you try and assign something to it but it's already const and you can't change something that's const. You could do it just like you did for the first const struct... or in C++ you could create a constructor for the struct and do the following:

Code:

const Note_Beats Song(Saints);

but I'm afraid your options are limited in C. Would a memcpy of the contents work perhaps (copying from one const struct to another)?

Im not trying to change the value of the const, im declaring it and setting it to be equal to the const Saints struct

and what is this code going to do??

Code:

const Note_Beats Song(Saints);

doesnt make any sense to do this???

Code:

{ {C6, 1}, {E6, 1}, {F6, 1}, {G6, 5},      {C6, 1}, {E6, 1}, {F6, 1}, {G6, 5},       {C6, 1}, {E6, 1}, {F6, 1}, {G6, 2}, {E6, 2}, {C6, 2}, {E6, 2}, {D6, 5} }

It lets you assign C6 etc for the int note part? Should have a 0x in front of that if it's supposed to be hex.
