To Print The Reverse Number

Write a program the outputs of number with the digits reversed.

#include <stdio.h>
#include <math.h>

int main()
{
    int intnumber;                           /* can try long for bigger range, int range is the limit*/
    int condition, remainder;
    int counter = 0, i = 0, j = 0;      /* counter to store the number of digit entered by user*/
    int counter1 = 0;                      /* counter1 is similar, used as for loop sentinel*/
    int reverseint[20];

    printf("Enter an integer number: ");
    scanf_s("%d", &intnumber);               /* read and store input in intnumber*/

    condition = intnumber;                       /* set the condition sentinel value to intnumber*/
    while (condition > 0)
    {
        condition = condition /10;
        counter = counter + 1;
            counter1 = counter1 + 1;         /* this counter for printing in reverse*/
    }
    counter = counter - 1;
    printf("The number in reverse: ");
    while (counter >= 0)
    {
        /* extract each of the decimal digits, need to cast to int*/
        /* to discard the fraction part*/
        /* pow(10, counter) used to determine the ...,10000, 1000, 100, 10, 1*/

        remainder = intnumber % (int) pow(10, counter);
        intnumber = intnumber/(int) pow(10,counter);
        reverseint[i] = intnumber;
        i++;
        intnumber = remainder;           /* update and repeat for the rest*/

        counter = counter - 1;
    }

    /* print the array element in reverse*/
  
    for (j=counter1-1; j >= 0; j--)
    printf("%d ", reverseint[j]);
    printf("\n");

    return 0;
