#include<stdio.h>
void main()
{
	char *a="your";
	char *b="name";
	printf("%s",strcpy(a,b));
}

You are copying string b to string a.

Unfortunately, string a is a literal which means the string is const. The compiler will not let you change the value of a literal.

Change the program to use arrays:

char a[] ="your";
char b[] ="name";
etc...

BTW: strcpy assumes the destination array is big enough to hold the source string. It's up to you to be sure this is true.
