I know filters, so I know it is Saturation.
Answer:
Option B, Vanishing point
Explanation:
The complete question is
Where do the projection lines converge in a perspective sketch?
A. the ground line
B. the vanishing line
C. the eye point
D. the horizon line
Solution
A point lying on the image of a perspective drawing where the drawings ( two-dimensional perspective projections) of two parallel line meet in three dimensional space is known as Vanishing point
Stack is LIFO data structure (Last In First Out) where the last element entered in stack will be the last one to be out of stack. It has three operations: push() : used to insert an element in stack, pop() : used to delete an element from the stack, top() : used to return the top of the stack i.e. the newest member of the stack. All these operations will take place at the top.
<u>Explanation:</u>
Now, looking at the program, x and y are initialized the values of 2 and 3 respectively. The stack pushes 8 onto the stack making it the first member of the stack. Then the value of x which is 2 is pushed onto the stack. Next, (x+5) = (2+5) = 7 is pushed onto the stack.
Pop() is used to delete hence 7 is popped out from the stack. top() is assigned to y which is 2 in this case and again 2 is popped out from the stack. Now, (x+y) = (2+2) = 4 is pushed onto the stack. And the top() is assigned to x which is 4. 4 is again popped out from the stack. Hence the value of x is 4.
The answer is the first one
Example of intermediate technology is the treadle pump, which enables farmers to provide a greater amount of water to their plants more easily compared to watering by bucket, while requiring much less infrastructure than constructing irrigation dams and pipes.
