# include<iostream.h>

//using namespace std;

# define PI 3.142;

int main ()

{

int Rad,Height;

double area;


cout<<"Enter the radius;";

cin>>Rad;

cout<<"Enter the Height;";

cin>>Height;

area = 3.142 * Rad * Rad * Height;

cout<<"Radius="<<Rad<<endl;

cout<<"Height="<<Height<<endl;

cout<<"The Area of the circle is"<<area<<"\n";

return 0;

1. Write a program that performs the following. The user inputs a number and then enters a series of numbers from 1 to that number. Your program should determine which number (or numbers) is missing or duplicated in the series, if any. For example, if the user entered 5 as the initial number and then entered the following sequences, the results should be as shown. Input Sequence Output ---------------------- --------------- 1 2 3 4 5 Nothing bad However, if 7 were the high number, the user would see the results on the right for the following number entries: Input Sequence Output ---------------------- --------------- 1 3 2 4 5 Missing 6 Missing 7 And if 10 were the high number and the user entered the numbers shown on the left, note the list of missing and duplicate numbers: Input Sequence Output ---------------------- --------------- 1 2 4 7 4 4 5 10 8 2 6 Duplicate 2 ( 2 times) Missing 3 Duplicate 4 ( 3 times ) Missing 9
