In the example, even if the order was salary and name, which is different from the way it is arranged in table, the code was executed. So here, if we interchange age and name, why is it showing incorrect!?

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

Hi, developers of sololearn! It is really good application for learning languages. But playing games is terrible. Why so little time for each round? If you will add new feature for players to be a to choose the duration of rounds, it would be great.

When dealing with propagation, if you set a <div> element to true, meaning it will use capturing, but set a child element, say <p>, to false so it uses bubbling, which event will take place first?

just asking. in C++, why do we need to define signed & unsigned integer? why don't we always use signed? it's better. we can freely assign plus and minus. so what's the catch of using unsigned?

While prototyping friend functions in a class is it necessary to always pass the address of the object as parameter?If so why is it that we have to pass address as parameter..In programs involving compositions we never used addresses...Why is the need for address of the objects while using friend?

How can I add an item at the end of the array? The most easy way (arr [5]=8) returns "out of range", and I suppose it's because first I instantiate it as "int [] arr=new int[5]", so it's out of the range. Can I amplify that range?

x = 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)?

so 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.
