How would I create a simple loop so that the person using this program (user) can keep inputting weights until they want to quit.
Also, I need trying to create a limit that the user can only enter in a certain range of numbers in the input. I want the user only to enter numbers between 0 and 1000. If they don't a error message should appear saying retry.
This is only my second code and it would mean alot to me if someone could lend me a hand.
Thanks in advance.
#include<iostream>
#include<cmath>
using namespace std;
int CheckWeight(int weight, string Planet);
int main()
{
int weight,res;
string planetName;
do{
cout << "Please enter your weight of your object to the nearest whole number." <<endl;
cin >> weight;}
while(cin.good()==false);
cout << " " << endl;
do{
cout << "Please enter a planet name from the following list." << endl;
cout << "Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune" << endl;
cin >> planetName;
cout << " " << endl;
// Call function to check weight
res = CheckWeight(weight, planetName);
}while(res==1);
system("PAUSE"); //pauses the program
return 0;
}// end main()
// Function for calculating weight
int CheckWeight(int weight, string Planet)
{
int Result=0;
if(Planet== "Mercury"){
cout << "Your weight on Mercury is " << (weight*0.4155)<< endl;
}
else if(Planet== "Venus"){
cout << "Your weight on Venus is " << (weight*0.8975)<< endl;
}
