I need help with my find function. It is coming up "Not Found" even when I enter a valid name. Please help me figure out what I am doing wrong. Here is my code...

//need to figure out how to add,delete, find, sort alphabetically
#include<iostream>
#include<cmath>

public:
bool input();
float sa();
float den();
void output();
void outputaf();
Planet();
bool sort();
bool add();
bool del();
void find();
//int Planet[], int qty
//bool find(int Planet[], int qty);
//int getsize();
//int find();
};

Planet::Planet()
{
char n[100];
float r = 0;
float m = 0;
}

void Planet::output()
{
cout<<"Name"<<n<<endl;

/////////////////////////////////

Also if any one knows how to do the add function and delete function it would be appreciated. I think I have to increase and decrease the number of elements in my array, but I am kind of clueless.

Thanks
