How many assignments would I have failed without brainy? Lol
ALL OF THEM
Answer:
previousAddition instance variable
Explanation:
In order to accomplish this you would need to add a previousAddition instance variable. In this variable you would need to save the amount that was added at the end of the process. Therefore, if a mistake were to occur you can simply call the previousAddition variable which would have that amount and subtract it from the total. This would quickly reverse the mistake, and can be easily called from the undo() method.
Answer:
The computer will follow the steps, but the program might not work.
Explanation:
False. As it is common knowledge, it is unnecessary for it to be documented.
Answer:
using namespace std;
int main()
{
float x,y;
cout<<"Enter a value of feet: ";
cin>>x;
y=x*0.305;
cout<<x<<" feet is "<<y<<" meters";
return 0;
}
Explanation:
The program is written in C++ language but the problem can be carried out in any language using the premises given here.
You have to declare your variables for feet and meters (x and y in this case). The you prompt the user via the message on screen given by the cout word and the << sign, and the value read via the cin word and the >> sign and stored into x. Then you multiply x by 0.305 and store it in y, and show them on screen via cout. Note that literal words are written between " " and variables are written just like that.
