Program to print the berth of given railway seat number

  • Last Updated : 30 Apr, 2021

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:
Output: side lower berth 
 

 

Approach: 
 

  • Check if seat number is valid seat number or not(i.e in range of 1 to 72). 
    1. if (seat_number % 8) equals 1 or 4, then berth is a lower berth
    2. if (seat_number % 8) equals 2 or 5, then berth is a middle berth
    3. if (seat_number % 8) equals 3 or 6, then berth is an upper berth
    4. if (seat_number % 8) equals 7, then berth is a side lower berth
    5. 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";
}
 
// Driver code
int main()
{
    int s = 10;
     
    // fxn call for berth type
    berth_type(s);
 
    s = 7;
     
    // fxn call for berth type
    berth_type(s);
 
    s = 0;
     
    // fxn call for berth type
    berth_type(s);
    return 0;
}

        if (s % 8 == 1 ||
            s % 8 == 4)
            printf("%d is lower berth\n", s);
             
        else if (s % 8 == 2 ||
                 s % 8 == 5)
