Question

I was writing a structure from a book, and then see how it does initialization.
I don’t get it, how he does that.

struct node
{
 char target[50];
 char stack[50];
 char *s,*t;
 int top;
}

Initialization function:

void init
{
 p->top = -1;
 strcpy(p->target,"");
 strcpy(p->stack,"");
 p-t = p->target;
 p->s="";
}

So I want know how he is using strcpy to initialize an array or char.

Answer 1

He is not doing it. The statement strcpy(p->target,""); does not initialize the 50 positions of the array. It just puts a 0 in the first position. (See this reference.)
