Problem description:  Consider the room numbers of our campus - 423, 432, 441, 234, 534, 132. Here first digit represents campus number, second digit represents floor number and the third number represents room number in that floor. Write a program that will take a three digit number (like 423) and output the Campus, Floor, and Room Number according to the input. INPUT: 423 OUTPUT: Campus 4, Floor 2, Room 3 Code: #include <stdio.h> int main() {     int n, campus, floor, room;     printf("Enter a room number: ");     scanf("%d", &n);     room = n%10;     floor = ((n - room)%100)/10;     campus = n/100;     printf("Campus %d, Floor %d, Room %d", campus, floor, room);     return 0; }
