SOLUTION TO QUESTION 1

HERE IS THE SOLUTION

/*PROGRAM TO DETERMINE ALL THE PYTHAGOREAN TRIPLETS WITHIN
 A SPECIFIED RANGE*/
#include<iostream.h>
#include<conio.h>
#include<math.h>
#include<process.h>

do

cout<<"\nENTER THE LOWER LIMIT: ";
cin>>l;
cout<<"\nENTER THE UPPER LIMIT: ";
cin>>u;
cout<<"\nPYTHAGOREAN TRIPLETS: "<<endl;
for(int i=l;i<=u;i++)

    for(int j=l;j<=u;j++)

        }
 }    }    }
if(n==1)
cout<<"\nNO TRIPLETS EXIST BETWEEN THE SPECIFIED RANGE"<<endl;
cout<<"\nDO YOU WISH TO FIND MORE TRIPLETS (Y/N): ";

clrscr();
}
while(w=='Y' || w=='y');
exit(0);
getch();
