Question

write a C++ program to add integer to the reverse of that integer till the first and last element is the same the program should print the integer thats the number and how many iterations to get to that number.

example

integer(number) = 363

reverse(of the number) = 363

363 +363 = 726 -------- 1

726 + 627 = 1353 --------- 2

1353 +3531 = 4884 ------- 3

stop print 4884 and 3

Answer 1

#include<iostream>
using namespace std;
int Reverse(int n)
{
int m,rev=0;
while(n)
{
m=n%10;
rev=rev*10+m;
n=n/10;
}
return rev;
}
int checkReverse(int n)
{
int m,rev=0,temp=n;
while(n)
{
m=n%10;
rev=rev*10+m;
n=n/10;
}
if(temp==rev)
return 1;
else
return 0;
}
int main()
{
int n,rev,counter=0;
cout<<"Enter an integer :";
cin>>n;
while(1){
counter++;
n=n+Reverse(n);
if(checkReverse(n))
break;
}
cout<<"The number is :"<<n<<endl;
cout<<"The number of iterations :"<<counter;
}

Output:
