[ad_1] By doing import java.sql.* you import all classes from the package java.sql at once, so that you don’t have to import them one by one. It’s more convenient to write when you’re importing many classes from some package. For example, instead of: import java.sql.Statement; import java.sql.ResultSet; import java.sql.Connection; // …etc. you can just write: … Read more
[ad_1] You need to use pow method of math.h from C-language. antilog = pow(10, number) ; This will give you antilog of number by base10 Side Note: As you are creating a Scientific Calculator and you would be needing Base for the number. EDIT: double number=74.5; double logOfNumber=log10(number); double antilog = pow(10, logOfNumber) ; NSLog(@”%lf”,antilog); … Read more
[ad_1] Character.toString(data) This fragment should not compile because this method accepts only single character. Use this call instead: String.valueOf(data) Also, new String(dataB) is redundant. Replace it with simply dataB 0 [ad_2] solved Converting char to string [closed]
[ad_1] Why not just update all after the id that was removed? Like that you don’t need a while, and performance will go up 300%. update questions set no = no – 1 where no > @yourRemovedID [ad_2] solved Loop is not working C#.net
[ad_1] Here is a solution for your problem: void main() { int n,m,oddSum=0,evenSum=0; printf(“Please insert the number for the program:”); scanf(“%d”,&n); int flag=0; int counter=1; while (n!=0) { if(counter%2==0) { evenSum += n % 10; n /= 10; } else { oddSum += n % 10; n /= 10; } counter++; } if(counter%2==0) { int … Read more
[ad_1] Without knowing why you want to use a single if, it’s hard to tell. Of course, you can use ternary operators without any ifs: unsigned int x, y; cin>>x; y = x<=1 ? 1 : x<=3 ? 2 : x<=5 ? 3 : 6; Or ugly boolean casting hacks for exactly one if (please … Read more
[ad_1] There are several issues in your code: highestSize and add are not initialized. In C++ variables are not default initialized to 0 as you might have expected. newArray is default constructed to have 0 elements. In this case you cannot use operator[] the way you did. operator[] can access only elements that were allocated. … Read more
[ad_1] The first line looks like an interface declaration. It is saying that a class has a method that accepts an integer and a string and returns an integer. Then it calls the method. However, this isn’t valid right now. I’m not sure if the rest was removed for brevity since you didn’t link to … Read more
[ad_1] Use this if (!bedSize.equals(“SINGLE”) && !bedSize.equals(“DOUBLE”) && !bedSize.equals(“KING”)) (If the bed size is different than “SINGLE” and different that “DOUBLE” and different than “KING”) [ad_2] solved If statement not comparing strings properly
[ad_1] Try this: # wait 2 seconds or use “sleep 2″ SECONDS=0; while [ $SECONDS -ne 2 ]; do :; done n=”” for ((i=0;i<30;i++)); do n+=”$(($RANDOM%10))”; done; echo “$n” See: help while, help test and help for 4 [ad_2] solved Linux 30-digit random number generator [closed]
[ad_1] If the result of the algorithm is in retval, return (!retval); 10 [ad_2] solved How to return opposite of true or false?
[ad_1] So far, you have the right idea. I am going to assume based on your syntax, that you are using an array. Your get() method looks good, but you are missing some code from your remove() method. public int remove(int index){ //check for out-of-bounds if(index < 0 || index >= size) //assumes size is … Read more
[ad_1] So, first thing you need to do is open the file so that you can see what’s in it. Here is the documentation for that, with examples. Make sure that you can see it line by line inside of a for loop by using the print function: for line in file: print(line) Now that … Read more
[ad_1] You should fix your indentations and all other errors: import random import time rock = 1 paper = 2 scissors = 3 names = { rock: “Rock” , paper: “Paper” , scissors: “Scissors” } rules = { rock: scissors , paper :rock , scissors: paper } player_score = 0 computer_score = 0 def start(): … Read more
[ad_1] Not exactly mine but just so people can clearly see for future learning and reference, I have subsequently received this answer from a member of the cod_ae_cademy pro team named Elise (:~)): “in this case it seems like [the codaecademy engineers] have a security setting to require that script [be called in directly from … Read more
