macros - Initialize array after declaring in C -

i trying following getting following error:

"error: expected expression before { token

test_stubs.h

#define signature 0x78,0x9c 

test.c

#include "test_stubs.h"  static unsigned myarray[100];  static void setup(void) {     myarray = {signature}; } 

edit

follow on question:

is there way assign individual values in #define specific indexes of myarray? instance...

#include "test_stubs.h"  static unsigned myarray[100];  static void setup(void) {     myarray[0] = signature[0]; //0x78     myarray[1] = signature[1]; //0x9c } 

clearly above code not code signature neither array or pointer.

as per c syntax rules, can initialize array using brace enclosed initializer list @ time of definition.

afterwards, have initialize element element, using loop, or, if need initialize elements same value, can consider using memset().

edit:

no, mentioned in comments, per code snippet, signature neither array name, nor represent array type, cannot use indexing on that.

however, using compound literal (on , above c99), if change #define, then, somehow, can make work. see below code example,

#include <stdio.h>  #define signature ((unsigned [100]){0x78,0x9c})  static unsigned myarray[100];  int main (void) {     myarray[0] = signature[0]; //0x78     myarray[1] = signature[1]; //0x9c      return 0; }
