How can you create a program that asks the user for the number of miles driven and the gallons of gas used?

Answer 1

That depends on the language. In C++ you might use the following:

#include<iostream>

using namespace std;

int main()

{

int miles, gas;

cout<<"Input the number of miles driven: ";

cin>>miles;

cout<<"Input the gallons of gas used: ";

cin>>gas;

cout<<"MPG: "<<miles/gas<<endl;

}

Of course when extracting user input you must always test the input is valid before operating upon it. If the user enters 0 gallons then you will end up with a divide by zero error.
