c=b*0.2;
cout<<"El costo total de kilometraje es de $"<<c;
break;
case 2:

a = 0;

}
}
system("pause");
return 0;
}

the format is

do
{

}while(condition)

you are missing the while.

I see a couple of small problems.

1. You have a do{, BUT no while. You could have it as }while (a !=0);
Place this as the line directly above system("pause");, replacing the current '}'

2. You declare the variable c to be an int, but try multiplying it with decimals. Make the variable c to be a double, instead.

3. Move the variables a,b and c, ABOVE the do statement, otherwise they are only seen in the do statement and not for the while part.

This should help tremendously.
