Question

What is the missing statement in the following function which copies string x into string y?

	void strcpy (char *x, char *y)
	{
		while (*y!='\0')
		................./*missing statement*/
		*x='\0';
	}
	

What will be the result of execution?

A x=y
B *x++=*y++
C (*x)++=(*y)++
D none of these
Answer & Explanation
Option: [B]

Pointer variable char *x is pointing to a location and the char *y is assigned to that location. If we assume the missing statement is *x++=*y++ then both the variables point to the next respective location till null ('\0') found.
