Answer:
I use google docs
Explanation:
I am in 6th grade but i am in expert in computers.
Solution:
It is important because, it has to do operation on so without, data structures and algorithms.
It performs these operation:
1)Take an input
2) Process it
3) Give back the output.
The input can be in any form, for ex while searching for directions on google maps, the starting point and the destination as input to google maps, while logging in to any social sites, We have to give our email and password as input and so on.
Similarly, in the third step, the computer application gives us output in some form or the other.
To make this process efficient, we need to optimize all the three steps.
Answer:
1.
class TIME
{
int hour , min , sec ;
public :
TIME()
{
hour=min=sec=0;
}
TIME( int h , int m , int s )
{
hour = h;
min = m;
sec = s;
}
void change ( int Hour)
{
hour = Hour;
}
void stdtime()
{
if(hour>12)
cout<<"The Standard time is"<<(hour-12)<<":"<<min<<":"<<sec<<"P.M\n";
else
cout<<"The Standard time is"<<hour<<":"<<min<<":"<<sec<<"A.M\n";
}
void miltime()
{
cout<<"The Military time is"<<hour<<":"<<min<<":"<<sec<<" hours\n";
}
};
void main()
{
TIME A , B(13,25,30);
A .stdtime();
A.change(23);
A.miltime();
B.stdtime();
B.change(9);
B.miltime();
}
2.
class elevator
{
int CurrentFloor;
int GoingUp;
int GoingDown;
public:
elevator()
{
CurrentFloor=0;
GoingUp=1;
GoingDown=-1;
}
elevator(int floor)
{
CurrentFloor=floor;
GoingUp=1;
GoingDown=-1;
}
void goUp(int y)
{
if( CurrentFloor>3)
cout<<"\nNO MORE FLOORS\n";
else
CurrentFloor=CurrentFloor+y*GoingUp;
}
void goDown(int x)
{
if(CurrentFloor<0)
cout<<"\nNO MORE FLOORS";
else
CurrentFloor=CurrentFloor+x*GoingDown;
}
};
void main()
{
elevator A(1);
A.goUp(1);
A.goUp(1);
A.goUp(1);
A.goDown(1);
A.goDown(1);
}
Answer:
Null
Explanation:
It entirely depends on the language you are using to implement this.
But generally by the rule of scope, "result" will return null since get() was not defined to accept any argument, and it neither know the global "x" not defined it's own x in the function.
