Didn't add details. Totally common sense program.
By the way, I didn't use strings due to the fact that this is meant to be a learning-program.Code:#include <iostream> #include <windows.h> using namespace std; int main() { double mpg; double miles; double costgas; double extra; cout<<"Welcome to the Trip Cost Calculator.\n\n"; Sleep(1000); while(1){ cout<<"\n\nEnter the miles per gallon your car goes on: "; cin>>mpg; Sleep(1000); cout<<"\n\nEnter the amount of miles you wish to venture during your trip: "; cin>>miles; Sleep(1000); cout<<"\n\nThe miles you wish to venture are "<<miles<<" on a car that goes "<<mpg<<" miles per gallon.\n\n"; Sleep(1000); cout<<"\n\nEnter the cost of each gallon of gas: "; cin>>costgas; Sleep(1000); cout<<"The miles you wish to venture are "<<miles<<" on a car that goes "<<mpg<<" miles per gallon."<<" The total cost of the trip will be "<<((miles/mpg)*costgas)<<" dollars before extra expenses.\n\n"; Sleep(1000); cout<<"Enter the extra expenses you will encounter during the trip: "; cin>>extra; Sleep(1000); cout<<"\n\nThe total cost will be "<<((miles/mpg)*costgas)+extra<<" dollars. Hopefully, this amount is very low and you will have lots of fun at your destination! Have fun!\n\n"; } }
