Using strcpy?

I have 2 strings.
char* a = "hi";
char* b = "";

How can I use strcpy to copy string a to string b?
please provide me the codes and give me explanation if possible.
Thank you very much.

Nope. In C, you have two pointers and one memory overflow.

Two strings would be like this:

Code:

char a[]="hi";
char b[309];

strcpy(b,a);

printf("%s\n%s\n");

Output:
hi
hi

printf("%s\n%s\n"); - something is missing. Two somethings...

Perhaps better questions are;

1. Why didn't you use strncpy()
2. Where does 309 come from?

For copying the string from source to destination.
always better use strncpy --> so that overflow can be avoided.

strncpy could leave the string without nul-terminator
