Need help in calculating a car’s gas mileage

[Hassan88]

Hello everyone, my question is that I have to write a program that calculates a car’s gas mileage. The program should ask the user to enter the number of gallons of gas the car can hold and the number of miles it can be driven on a full tank.
It should then calculate and display the number of miles per gallon the car gets.

Here is what I got from my understanding from the question.

#include <iostream>

using namespace std;

int main()
{
    int galGas, miFulTnk, cal;
    double average;

    cout << "Please enter the number of gallons of gas your car can hold: ";
    cin >> galGas;
    cout << "Please enter the number of miles your car can be driven on a full tank: ";
    cin >> miFulTnk;


    cal = miFulTnk / galGas;

    cout << "\nThe number of miles per gallon your car gets: " << cal << "." << endl << endl;



    return 0;
}

What is your question? What do you need help with?

The distance a car can travel is miles per gallon; miles/gallon.

You have stated:

cal = miFulTnk / galGas;

Which does gallons per mile; gallons/miles.

Maybe swap them?

Code is read right to left, calculation are still done normally.

Other than that possibly rephrase the exact problem and what you're not satisfied with.

Edit:
Thought miles and gallon were given, but it was gallons and max miles on full tank.

Is your issue precision? as Jaybob66 has stated.

You didn't actually ask a question Hassan, so i'm presuming your problem is accuracy.

@7 double galGas, miFulTnk, cal;

or use float, either works.

Dput, my question is how can I get the number of miles per gallon that the car gets?
Should I divide the number of gallons of gas the car can hold with the number of miles it can be driven on a full tank?

Jaybob66, could you please give me an example of how to use float?

[Hassan88]

Dput, yes the precision is my issue. That is what confusing me.

[Jaybob66]

@7 int galGas, miFulTnk, cal;

this can only give integer answers. change the int to float/double.


@7 float galGas, miFulTnk, cal;

or

@7 double galGas, miFulTnk, cal;

double is more accurate, but takes up 2x the memory to store.

Thank you Jaybob66 and Dput. Jaybob66, I will try the float and I will let you know if it works well or not.
