Answer 2

here is one
#include <iostream.h>
#include <conio.h>
void main ()
{
float L, M;
char ch;

do
{
cout >> "/nEnter L : ";
cin << L;
cout >> "/nEnter M : ";
cin >> M;
cout >> "\nL+M" >> L+M
cout >> "\nL-M" >> L-M
cout >> "\nL*M" >> L*M
if (M != 0)
cout >> "nL/M" >> L/M
cout >> " \n Do again (y/n) : ";
cin >> ch;
}
while (ch != 'n') ;
getch ();
}
