C++ Program to reverse number

We can reverse a number in C++ using loop and arithmetic operators. In this program, we are getting number as input from the user and reversing that number.

Let’s see a simple C++ example to reverse a given number.

 #include <iostream> using namespace std; int main() { int n, reverse=0, rem;   cout<<“Enter a number: “;   cin>>n;     while(n!=0)     {        rem=n%10;          reverse=reverse*10+rem;        n/=10;     }    cout<<“Reversed Number: “<<reverse<<endl;    return 0; } 

Output:

Enter a number: 234    Reversed Number: 432
