Good Afternoon,
I am from brasil, and i am beginning to study programming, I bought the book "C++ How To Program", and i am now trying to make a small software with each class in its file, with prototypes and etc, here is a simple program that i made to try to fix my problem, here is the code:
File Echoit.h
Echoit.h
#include <string>
using std::string;
class Echoit
{
public:
void setWord(string);
string getWord();
void displayWord();
private:
string typedWord;
};
File Echoit.cpp
___
Echoit.cpp
#include <iostream>
using std::cout;
using std::cin;
using std::endl;
#include "Echoit.h"
#include <string>
using std::string;
Echoit::setWord( string name )
{
typedWord = name;
}
Echoit::getWord()
{
return typedWord;
}
Echoit::displayWord()
{
cout << "A palavra digitada é: " << getWord() << endl;
cout << endl;
}
File main.cpp
__
main.cpp
#include <iostream>
#include "Echoit.h"
#include <string>
using std::cout;
using std::cin;
using std::endl;
using std::string;
using std::getline;
int main()
{
string palavradigitada;
Echoit echoIt1;
cout << "Digite a palavra: " << endl;
getline ( cin, palavradigitada );
echoIt1.setWord( palavradigitada );
echoIt1.displayWord();
return 0;
}
__
When i try to compile this with g++, i get this error:
mudesto@modesto:~/workdir/teste$ g++ main.cpp -o teste
/tmp/ccKD3ike.o: In function `main':
main.cpp:(.text+0xdc): undefined reference to `Echoit::setWord(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)'
