Homemade String Class

#include<iostream>
using namespace std;

class String1 {
private:
char str[80];
public:
// Constructors

// Fill a character buffer argument
void GetString(char *);

// Concatenation Operators
String1 operator+(String1 &);
String1 operator+(char *);
friend String1 operator+(char *, String1 &);

// Assignment Operators

// would work without this cuz we do not have
// any pointer members but do anyway for practice
String1 operator=( String1 &);
String1 operator=( char *);

// Console Stream Output
friend ostream &operator<<(ostream &, const String1 &);
};


ostream & operator<<(ostream & stream, sIn &)

}
void String1::GetString(char * strBufPtr)
{

}
String1::String1(char * strIn)
{

}

void main()
{
String1 S("Bob");
char buffer[20];
S.GetString(buffer);
cout << buffer;

//String1 S1, S2("Bob"), S3("Jones");
//S1 = S2;
//S1 = S2 + S3("Bob"), S3("Jones");
// String1 S1, S2("Bob");
//cout << S1<< S1;
}

Um:

char str[80];

Please use code tags...and what issues are you having exactly?

[hallux2003]

functionality of the class.

class String1 {
private:
char str[80];
public:
// Constructors
String1();
String1(char *);

// Fill a character buffer argument
void GetString(char *);

// Concatenation Operators
String1 operator+(String1 &);
String1 operator+(char *);
friend String1 operator+(char *, String1 &);

// Assignment Operators

// would work without this cuz we do not have
// any pointer members but do anyway for practice
String1 operator=( String1 &);
String1 operator=( char *);

// Console Stream Output
friend ostream &operator<<(ostream &, const String1 &);
};

Be sure to fully test all the functions in main. Main should have lines of the following form, plus more to test the constructor calls, output, etc.

"Dan " + S; // calls friend operator+(char *, String1 &);
S + "Bob"; // calls operator+(char *);
S + S; // calls operator+(String1 &);
S = S3; // calls operator=( String1 &);
S = "Bob"; // calls operator=( char *);
cout << S // calls friend ostream &operator<<(ostream &, const String1 &);

His main issue is that he has got a number in his class name

[hallux2003]

taking the number out of the class name doesn't change anything.

code tags?

That looks great how do I use code tags?

The problem I am having is: I have most of this written down but I need a shove in the right direction so I can figure out what I am doing wrong.

My post wasn't meant to solve your problem. Instead it should point out that numbers in identifiers are generally or even always a bad idea.
