Error on declaring an array of structures

I have to declare an array of structures of size 16. The following code gives an error code1.c:12:1: error: initializer element is not constant

typedef struct node 
{
int tokenvalue;
struct  node *next;
char *n;
} node;
node *dummy=(node *)malloc(26*sizeof(node));

Also using node dummy[26] gives segmentation fault. What should I do?

Try initializing it in your main() function as you cannot initialize global variables with non-constant values or values that cannot be determined at compile time.

Alternatively you can declare it as

node dummy[27];

as a global variable instead of having to use malloc (if the size is constant).

You can't initialize objects having static storage with anything non compile-time constant. Leave it uninitialized and assign some memory to it in a function.
