Answer:
Attempts to modify the value of a variable defined const are caught at execution time
Explanation:
The false statement among the options is Attempts to edit the value of a variable defined const are caught at execution time while other options are true.
A const variable should not be modify because the main reason of having a const variable is not to make modifying it possible. If you prefer a variable which you may likely want to modify at some point, then don't just add a const qualifier on it. Furthermore, Any code which modify's a const by force via (pointer) hackery invokes Undefined Behavior
Answer:
An overhead projector: requires slides to project images
A laptop: requires an external monitor to project high-resolution images
A computer: requires a CD-ROM drive to run presentation CDs
An external monitor: requires a port to connect to the laptop
Explanation:
The correct pair has been formed above. An overhead projector requires the slides for projecting images. A Laptop for projecting high-resolution images requires an external monitor. And a computer requires a CD-ROM drive for running presentation CDs, and an external monitor requires a port to a port which can be an HDMI port to connect to a laptop.
Answer:
- public class Square {
- public static boolean isPerfectSquare(int n){
- int sqrt_n = (int) Math.sqrt(n);
- if(sqrt_n * sqrt_n == n ){
- return true;
- }else{
- return false;
- }
- }
- }
Explanation:
Firstly, use sqrt method from Math package to calculate the square root of input n (Line 3). Cast the result to integer and assign it to sqrt_n variable.
Next, square the sqrt_n and check if it is equal to input n (Line 4). If so, return true, if not, return false (Line 4-8).
Answer:
Explanation: The first thing to calculate is what IP addresses are used by the largest LAN. Because the LAN has 100 hosts, 7 bits must be left for host bits.
