Given a railway seat number, the task is to check whether it is a valid seat number or not. Also print its berth type i.e lower berth, middle berth, upper berth, side lower berth, side upper berth as per the figure below.
Examples:
Input: 10
Output: middle berth
Input: 7
Output: side lower berth
Approach:
- Check if seat number is valid seat number or not(i.e in range of 1 to 72).
- if (seat_number % 8) equals 1 or 4, then berth is a lower berth
- if (seat_number % 8) equals 2 or 5, then berth is a middle berth
- if (seat_number % 8) equals 3 or 6, then berth is an upper berth
- if (seat_number % 8) equals 7, then berth is a side lower berth
- if (seat_number % 8) equals 0 then berth is a side upper berth
Below is the implementation of the above approach:
C++
// C++ program to print
// berth type of a provided
// seat number.
#include <bits/stdc++.h>
#include <iomanip>
#include <iostream>
#include <math.h>
using namespace std;
// function to print berth type
void berth_type(int s)
{
std::cout << std::fixed;
std::cout << std::setprecision(2);
if (s > 0 && s < 73)
if (s % 8 == 1 ||
s % 8 == 4)
cout << s << " is a lower berth\n";
else if (s % 8 == 2 ||
s % 8 == 5)
cout << s << " is a middle berth\n";
else if(s % 8 == 3 ||
s % 8 == 6)
cout << s << " is a upper berth\n";
else if(s % 8 == 7)
cout << s << " is a side lower berth\n";
else
cout << s << " is a side upper berth\n";
else
cout << s << " invalid seat number\n";
}
