4 issues

(1) no return value. ( should return a char - as the method name suggests so).
(2) Cannot assign a char to string variable
(3) no error checking for incoming string ( what if s is null?)
(4) if we need 3rd char of the string, we should check if the string has atleast 3 chars.

Hi buddy s above query is compiler error because "s" is not string array.

I corrected it as
public int getchar(string s)
{
if(s!=null)
if(s.length()>4)
char c=s[3];
}

public int getchar(string s)
{
string s1=s[3]; // the error is: can not implicitly convert a char to string
return 0; /// and this needs a return value
}
