Dear Learner,

Here is the C++ code for converting gallons to liters.

NOTE:- the formula for converting used in the code is 1 (US)Gallon = 3.78541 Liters

CODE:

#include<iostream>
using namespace std;

main()
{ float gallons,liters; //variables to store the quantities
cout<<"Enter the quantity in gallons :"; //asking the user to enter the volume in gallons
cin>>gallons; //storing the input in 'gallons' variable. NOTE that the float datatype will allow the user to enter amount with decimal places
liters = 3.78541 * gallons; //calculating corresponding liters
cout<<"\n"<<gallons<<" gallons = "<<liters<<" liters"; //displaing the result
}
