Automatic inline functions

int i; // private by default
public:

void setInt(int j) { i = j; }
} ;
int main()
{

s.setInt(10);
cout << s.getInt();
return 0;

Defines constructor, destructor, and range() function in-line
#include <iostream>
using namespace std;

// These are now private.
int a;
int b;

public:

}
// Compute and return the range.
int range() {

}
// Accessor functions.
int getA() { return a; }
int getB() { return b; }
int getC() { return c; }
};
