Question

• Selection control structure
  • The if statement
  • The switch statement (optional)
• Relational operators and logical operators
  • Use of relational and logical operators to check numeric ranges
• User friendly
  • Use of user friendly user prompt and simple input validation
  • Use of meaningful output labels and format
  • Use of output manipulators
• Working with string type
• Use of getline()

Project Description

There are two main systems for measuring distance, weight and temperature, the Imperial System of Measurement and the Metric System of Measurement. Most countries use the Metric System, which uses the measuring units such as meters and grams and adds prefixes like kilo, milli and centi to count orders of magnitude. In the United States, we use the older Imperial system, where things are measured in feet, inches and pounds.

Write a program that shows the following menu options and lets the user to convert from Metric to Imperial system:

Converter Toolkit

--------------------

    1. Temperature Converter

    2. Distance Converter

    3. Weight Converter

    4. Quit

• If the user enters 1, the program should ask for the temperature in Celsius and convert it to Fahrenheit
• If the user enters 2, the program should ask for the distance in Kilometer and convert it to Mile
• If the use enters 3, the program should ask for the weight in Kilogram and convert it to Pound
• If the user enters 4, the program should end.

Project Specifications

Input for this project:

• the user must enter an number to select a menu option
• the user must enter temperature in Celsius
• the user must enter distance in Kilometer
• the user must enter weight in Kilogram
• the user must enter a country name

Input Validation:

• Do not accept a number outside the range of 1 through 4 for the menu option. Be sure to display appropriate error message if the input is invalid.
• Do not accept negative numbers for distance and weight. Be sure to display appropriate error message if the input is invalid.

Output: The program should display the following:

• a menu for Converter Toolkit
• temperature in Fahrenheit, distance in miles or weight in pounds
• a country name
• Programmer’s full name
• project number
• a due date

Processing Requirements

1. The program should use at least one selection control structure (if – else statement)
2. Be sure to convert as specified. For example, convert temperature from Celsius to Fahrenheit, not the other way around.
3. Use the following for converting input:

• 1 kilometer = 0.6 mile,
• 1 kilogram = 2.2 pounds,
• The formula for converting Celsius degree to Fahrenheit is:

F = (9/5)*C + 32 where F is the temperature in Fahrenheit and C is the temperature in Celsius

4. Convert temperature to a whole number such as 78, distance to two positions after decimal point (for example 84.56) and weight to one position after decimal point (For example 121.6).

Plz give the code and flow chart, thank you so much!!!

Answer 1

Flow chart:

Source code ( C++):

#include<iostream>
#include<conio.h>
#include<stdio.h>
using namespace std;
void main()
{
   int choice;
   float c,d,k,m,f,p;//c-temperature in celcius,d-distance in kilometer,k-weight in kilogram,m-distance in miles,f-temperature in fahrenheit

   do //loop to make the program a menudriven program
   {
       cout<<"\nChoose the option from the given below\n";//choice dispaly
       cout<<"1. Temperature Converter\n";
       cout<<"2. Distance Converter\n";
       cout<<"3. Weight Converter\n";
       cout<<"4. Quit\n";
       cin>>choice;
       switch(choice)
       {
       case 1: //to convert temperature in fahrenheit
           cout<<"\nEnter the temperature in celcius\n";
           cin>>c;
           f=((9.0/5)*c)+32;
           cout<<"\nTemperature in fahrenheit is "<<f;
           break;
       case 2: //to convert distance in miles
           cout<<"\nEnter the distance in kilometers\n";
           cin>>d;
           m=d*0.6;
           cout<<"\nDistance in mile is "<<m;
           break;
       case 3: // to convert weight in pound
           cout<<"\nEnter the weight in kilogram\n";
           cin>>k;
           p=k*2.2;
           cout<<"\nWeight in pounds is "<<p;
           break;
       case 4: // to quit
           break;
       default : // for wrong input
           cout<<"\nEntered a wrong choice";
       }
   }while(choice!=4);
}
