Answer 1

#include<iostream.h>

int main ()

{

int num , rem , a , b , c , d , x , y ;

cout<<"Enter a four digit number ";

cin>>num;

a=num/1000;

rem=num%1000;

b=rem/100;

rem=rem%100;

c=rem/10;

rem=rem%10;

d=rem/1;

cout<<d<<c<<b<<a<<endl;

a=(a+7)%10;

b= (b+7)%10;

c= (c+7)%10;

d= (d+7)%10;

cout<<a<<b<<c<<d<<endl;

x=a;

a=c;

c=x;

y=b;

b=d;

d=y;

cout<<"The encrypted integer is ";

cout<<a<<b<<c<<d<<endl;

system("pause");

return 0;

}
