Explanation:
The language I use would do it as
h1$ = copy(h$,1,3)
This may not satisfy you, because your language could be quite different. You might want an input statement of some kind that would define h$. This assumes that somewhere h,h1 are declared as strings.
You also have to know how to read an input. My language uses readln(input,h)
and how to write it on the screen write(h1) or writeln(h1)
The if statement should have two equal signs, the elseif should be elif, and the else statement should have a colon at the end of it. There might be more errors in the indentation but I cant know unless I see a picture of the problem. The print statement should be indented into the if, elif, and else statements.
