Question

Write a C++ program that asks the user to enter his or her weight and the name of a planet. The program then outputs how much the user would weigh on that planet. The following table gives the factor by which the weight must be multiplied for each planet. The program should output an error message if the user doesn't type a correct planet name. The prompt and the error message should make it clear to the user how a planet name must be entered. Be sure to use proper formatting and appropriate comments in your code. The output should be labeled clearly and formatted neatly. [100 Points] 2.

Explanation / Answer

PLEASE REFER BELOW CODE

#include<iostream>

#include<map>

using namespace std;

int main()

{

std::string Planet_name;

double weight,final_weight;

std::map<string,double> mymap; //creating Map of key value pair with key as planet name and value as weight factor

std::map<string,double>::iterator it; //iterator for map

//creating map with Name and weight factor

mymap.insert(std::pair<string, double>("Mercury", 0.4155));

mymap.insert(std::pair<string, double>("Venus", 0.8975));

mymap.insert(std::pair<string, double>("Earth", 1.0));

mymap.insert(std::pair<string, double>("Moon", 0.166));

mymap.insert(std::pair<string, double>("Mars", 0.3507));

mymap.insert(std::pair<string, double>("Jupiter", 2.5374));

mymap.insert(std::pair<string, double>("Saturn", 1.0677));

mymap.insert(std::pair<string, double>("Uranus", 0.8947));

mymap.insert(std::pair<string, double>("Neptune", 1.1794));

mymap.insert(std::pair<string, double>("Pluto", 0.0899));

//Asking user input

cout<<"Please enter weight in Kg: ";

cin>>weight;

//do while() loop for asking user to enter planet name correctly

do{

cout<<"Choose amongst below list "<<endl;

cout<<"Mercury Venus Earth Moon Mars Jupiter Saturn Uranus Neptune Pluto "<<endl;

cout<<"Please enter Planet Name : ";

cin>>Planet_name;

it = mymap.find(Planet_name); //finding planet name in map

if (it != mymap.end()) //if string is in map

{

final_weight = it->second * weight; //multiplying weight with factor

cout<<"Weight on "<<Planet_name<<" is "<<final_weight<<" Kg"<<endl;

break;

}

else //repeating do while() loop

{

cout<<"Incorrect Planet name "<<endl;

}

}while(1);

return 0;

}
