Question

class X
{
 private: 
    string DATA;

. 
.
. 

  const string read_entry( const string & s )   {   return this->(DATA[1]); } //Error


}

What’s wrong with this? I’m trying to access the index of the DATA string, but I get an error when I do this->DATA[1]

Answer 1

The problem appears to be the return type of the function. The stated type is const string but indexing into a string returns a char. Try the following instead

char read_entry( const string & s )   {   return this->DATA[1]; }
