#include <iostream.h>
#include <conio.h>
#include <iomanip.h>
#include <math.h>

class exponent
{

public:

{i=0;j=0.0;}
void display(void);
};

void exponent :: display(void)
{
double sum;
    cout<<"\n\n\t\t\tTABLE FOR Y = EXP[-X]\n";
    for(int a=0;a<40;a++)
        cout<<"--";
    cout<<"\n";
    for(int c=0,b=0.0;c<10;b++,c++)

        else

    }
    cout<<endl;

            if(c==0)
               cout<<setw(5)<<i;
            else
