Program to convert given weeks to hours

Given a positive integer W which represents the number of weeks, your task is to convert it to the total number of hours.

Examples:

Input: W=15
Output: 2520

Input: W=1
Output: 168

Approach: To solve the problem, follow the below idea:

The problem can be solved using simple mathematical conversions:

1 Week = 7 days
1 Day = 24 hours

Step-by-step algorithm:

Create a function WeekToDays() that converts the number of weeks to equivalent number of days using the formula:
- 1 Week = 7 days
Use a function DaysToWeek() to convert the days to equivalent number of hours using the formula:
- 1 Day = 24 hours

Below is the implementation of the algorithm:

C++

#include <bits/stdc++.h>
using namespace std;
// funtion to convert week to days
int WeekToDay(int weeks)
{
    int days = weeks * 7;
    return days;
}
// funtion to convert Days to hours
int DayToHour(int days)
{
    int hours = days * 24;
    return hours;
}
// driver code
int main()
{
    int weeks = 15;
    // get total number of days from week
    int days = WeekToDay(weeks);
    // get total number of hours from days
    int hours = DayToHour(days);
    cout << hours << endl;
    weeks = 1;
    // get total number of days from week
    days = WeekToDay(weeks);
    // get total number of hours from days
    hours = DayToHour(days);
    cout << hours << endl;
}

Java

public class TimeConversion {
    // Function to convert weeks to days
    static int weekToDay(int weeks) {
        int days = weeks * 7;
        return days;
    }

    // Function to convert days to hours
    static int dayToHour(int days) {
        int hours = days * 24;
        return hours;
    }

    // Driver code
    public static void main(String[] args) {
        // Given weeks
        int weeks = 15;

        // Get total number of days from weeks
        int days = weekToDay(weeks);

        // Get total number of hours from days
        int hours = dayToHour(days);

        // Print the result
        System.out.println(hours);

        // Update weeks
        weeks = 1;

        // Get total number of days from weeks
        days = weekToDay(weeks);

        // Get total number of hours from days
        hours = dayToHour(days);

        // Print the result
        System.out.println(hours);
    }
}

Python3

# Function to convert weeks to days
def week_to_day(weeks):
    days = weeks * 7
    return days

# Function to convert days to hours
def day_to_hour(days):
    hours = days * 24
    return hours

# Driver code
if __name__ == "__main__":
    # Given weeks
    weeks = 15

    # Get total number of days from weeks
    days = week_to_day(weeks)

    # Get total number of hours from days
    hours = day_to_hour(days)

    # Print the result
    print(hours)

    # Update weeks
    weeks = 1

    # Get total number of days from weeks
    days = week_to_day(weeks)

    # Get total number of hours from days
    hours = day_to_hour(days)

    # Print the result
    print(hours)

using System;

class Program

    }

    // Function to convert days to hours
    static int DayToHour(int days)

        int hours = days * 24;
        return hours;
    }

    // Main function
    static void Main()
    {
        int weeks = 15;
        
        // Get the total number of days from weeks
        int days = WeekToDay(weeks);

        // Get the total number of hours from days
        int hours = DayToHour(days);

        Console.WriteLine(hours);

        weeks = 1;

        // Get the total number of days from weeks
        days = WeekToDay(weeks);

        // Get the total number of hours from days
        hours = DayToHour(days);

        Console.WriteLine(hours);

JavaScript

// Function to convert weeks to days
function weekToDay(weeks) {
    var days = weeks * 7;
    return days;
}

// Function to convert days to hours
function dayToHour(days) {
    var hours = days * 24;
    return hours;
}

// Driver code
// Given weeks
var weeks = 15;

// Get total number of days from weeks
var days = weekToDay(weeks);

// Get total number of hours from days
var hours = dayToHour(days);

// Print the result
console.log(hours);

// Update weeks
weeks = 1;

// Get total number of days from weeks
days = weekToDay(weeks);

// Get total number of hours from days
hours = dayToHour(days);

// Print the result
console.log(hours);
