Question

I was using the topcoder C++ compiler, and although this code just run fine in Linux gcc, the topcoder compiler gave this error:

your code did not compile:

errors compiling:

Your class or method was improperly declared: In function
   ‘std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, 
   std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > _wrapper::thunk(std::string)’:

Your class or method was improperly declared:20034: 
error: conversion from ‘void’ to non-scalar type
‘std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, 
std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >’ requested

This is the code snippet where it is flagging error:

class BinaryCode {

    public:
            static int get_digit(char c)
            {
                    return (c-'0');
            }
            void decode(string decd)
            {
                    int i;

                    std::vector <int> decoded(decd.size());
                    std::transform(decd.begin(), decd.end(), decoded.begin(), &get_digit);

                    int length=decoded.size();

This is the topcoder problem description:

Definition Class:BinaryCode
Method:decode

Parameters:string
Returns:vector <string>

Method signature:
vector <string> decode(string message)

(be sure your method is public)
    

Answer 1

Your method signature is:

void decode(string decd)

Should be:

vector <string> decode(string message)

TopCoder compiles your code with testing code for the problem. Make sure the code you provide meets the requirements in the problem statement.
