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  int main()   {   int n, reverse=0, rem;   printf(“Enter a number: “);     scanf(“%d”, &n);     while(n!=0)     {        rem=n%10;        reverse=reverse*10+rem;        n/=10;     }     printf(“Reversed Number: %d”,reverse);   return 0; }  

Output:

Enter a number: 123 Reversed Number: 321
