Can someone explain this code to me....
class ReverseNumberDemo
{ public static void main(String args[]) {
int num=123456789;
int reversenum =0;
while( num != 0 ) {
reversenum = reversenum * 10;
reversenum = reversenum + num%10;
num = num/10; }
System.out.println("Reverse of specified number is: "+reversenum);
}
}
the thing I don't get is the reversenum part......isn't reversenum=0 so wouldn't reversenum*10=0

4 ответовI have a PHP multiD array like array($arrayA, $arrayB, $arrayA, $arrayC, $arrayC, $arrayA...........)
ho can I get a resulting array which have distinct elements from this array and sorted with the more occurance first like...
array( $arrayA, $arrayB, $arrayC)
because array $arrayA was 3 tumes in first array so it comes first in resulting array.

3 ответовx = 42;
int num = 0;
while (num <3)
Consele.writeline (x);
num++;
int x = 42; is just an int with an asigned value of 42
int num=0; is what initiate the count for the while loop
while (num < 3); means 0<3 true, 1< 3 true, 2<3 true, the loop end at 2 bc 3 <3 is false
consele.writeline (x) will display 42 while num < 3
num++ will execute and then add 1 to check if the while loop still true, but it stop at 2, bc 3 makes it false.
so the consele.write will write 42 three times. x=42, remember the (x)

so although using srand(time(0)) can be used to get truly random numbers, how truly random are they? For example, if one were to call this method at the same time (in this example, if one were to use this command at 51s) each time would the numbers generated be the same???
If so, are the numbers still truly random??
And if this theory is true, how can one generate truly random numbers that cannot repeat based on external variables (e.g., time)?

1 ответI have 10 variables called, int1, int2, int 3 and so on. The user can write one number into the console. If the user types 7, I want to add 3 to the value of int7. how do I do this without 10 if statements? can I somehow do something like, (int + "userinput") += 3?
thank you for your help! :D

2 ответовso far in section 1 question 2 area all of the videos have been ads that if you skip the add it just brings up the questions you need to answer. also if you play the add all the way thru you get the same exact thing. luckily I'm using this as a refresher course but I would think if I didn't know anything about c++ then I could be pretty lost missing videos.
