b) SWITCH STATEMENT

Expert's answer

#include<stdio.h>

main()

{

int last_digit, number, next_digit, rev_num;

printf ("Enter the five-digit number that has to be reversed and checked for equality:");

scanf("%d", &number);

last_digit = number - ((number / 10) * 10); /*units place*/

rev_num = last_digit; /* 5 */

next_digit = (number / 10) - ((number / 100) * 10); /*tenth's place*/

rev_num = (rev_num * 10) + next_digit; /*54*/

next_digit = (number / 100) - ((number / 1000) * 10); /*hundred's place*/

rev_num = (rev_num * 10) + next_digit; /*543*/

next_digit = (number / 1000) - ((number / 10000) * 10); /*thousand's place*/

rev_num = (rev_num * 10) + next_digit; /*5432*/

next_digit = (number / 10000) - ((number / 100000) * 10); /*ten thousand's place*/

rev_num = (rev_num * 10) + next_digit; /*54321*/

printf ("The Reversed Number is: %d",rev_num);

if (rev_num==number)

{

printf("\nEntered number and reversed number are equal\n");

}

else
