using strcpy in c++ error

Can you please tell me what's wrong with this code?
I need to use strcpy for my homework and I keep getting a "Run-time check failure #2:Stack around st2 was corrupted"

btw, I am trying to just print State

Thanks guys!

#include<iostream>
#include<cstring>

using namespace std;

int main(){
	char st1[20]="State of Ca";
	char st2[5]={' '};

	strcpy(st2, st1);
	cout<<st2<<endl;
	
return 0;
}

is there any way I could use strcpy?

crysallus

strcpy always copies the whole of the source (st1), into the destination (st2), as such the destination must be at least as large as the source, including null-terminating character.

So, to copy only "State", or have the destination string smaller than the source, no.

oops, crysallus, I didn't see that you said "including null-terminating character". So, never mind.

Actually, you were still kind of right to pick up on that, as I hadn't put 6 in my sample code in my first post, which I should have.

But yes, my explanation there probably should have got that across.
