C Program to Find Reverse of a Number using for loop

Declare and initialise the following three variables: int number,rem,reversed Num=0;
The user is prompted to provide a number, which is saved in the integer variable ‘number.’
The for loop is used to find the inverse of a given number.
The for loop will continue to run until ‘number’ is not equal to zero.
Finally, the output is shown as a reversed number.

Source code:

 #include<stdio.h>
 int main()
 {
     int number,rem, reversed;

     printf("Enter a number: ");
     scanf("%d",&number);

     for(reversed=0; number!=0; number /= 10)
     {
         rem = number%10;
         reversed = (reversed*10) + rem;
     }

     printf("Reverse Number = %d\n",reversed);

     return 0;
 }

Output:

Enter a number: 456
Reverse Number = 654
