C Program to Find Reverse of a Number using while loop

Explanation:

Declare and initialize the following three variables: int number, rem, reversed =0;
The user is prompted to provide a number, which is saved in the integer variable ‘number’.
The while loop is used to calculate the inverse of a given integer.
The while loop runs until ‘number’ is not equal to zero.
Finally, the output is shown as a reversed number.

Program:

 #include<stdio.h>
 int main()
 {
     int number,rem, reversed=0;

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

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

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

     return 0;
 }

Output:

Enter a number: 521
Reverse Number = 125
