Question

Develop a program that uses four signed, global, short variables A, B, C, D Initialize each variable A, B, C, D to a different positive one-digit value Somehow print the four values in order A B C D, space separated Print a newline character Reorder the values in the variables from the order A, B, C, D to B, C, D, A

A -> B

B -> C

C -> D

D -> A

Somehow print the four values in order A B C D, space separated

Hi,

Hope you are doing fine. I have coded the above question in C++. The logic is same irrespective of any language. All the conditions as per the question have been met. The code has been clearly explained using comments that have been highlighted in bold.

Program:

#include <iostream>

using namespace std;

//declaring global signed short int variables and initializing them.
signed short int A=1,B=2,C=3,D=4;

int main()
{
   //printing each variable, seperating them by space
   cout << A <<" "<<B<<" "<<C<<" "<<D;
   //printing a new line character
   cout <<"\n";
   //declaring local variables that will store the values of A,B,C,D
   signed short temp1,temp2,temp3,temp4;
   //storing values of A, B, C, D into temp variables
   temp1=A;
   temp2=B;
   temp3=C;
   temp4=D;
   //changing the values of A, B, C, D using the values in temp variables as per the order mentioned in the question
   A=temp2;
   B=temp3;
   C=temp4;
   D=temp1;
   //printing each variable, seperating them by space
   cout << A <<" "<<B<<" "<<C<<" "<<D;
}
