Int *m=new int [31];

Float *m=new float[8];

Double *m=new double[8];

Long *m=new long[16]

2-When print the address of the fifth character in pointer n on the screen :

Printf("%p", n+5);

Printf("%p",&n[4]);

Printf("%p",n[5]);

3-to see the moving of a circle (circle(x,y,10)) from left top corner to right lower corner on the screen we need to ___________________

increase x and decrease y

increase x and increase y after every 0.0001 ms

increase x and decrease y after every 100 ms

increase x and increase y after every 100 ms

4-arc(0,0,90,270,40); draw seen half circle

False

True

Answer 1

For the given options, the best suits are as follows:

Double uses 8 bytes of data so 8*8 = 64 bytes

And '&' denotes address of certain data.



As moving on the screen x has to be increased and y has to be decreased as per the requirement.

And the arc function depicts the previous diagram.
