So I have a poker type program where it should shuffle and deal a deck of cards using arrays of pointers. I have to write a function that uses a pointer(s) to determine if the hand contains an Ace. If I can understand this one, I'd be able to do the rest with no problems. I was told to do what I did with int decks, int dealt, int the_hand, but I keep getting errors. I've been trying everything I could think of, but no luck. Am I even in the right direction? Also, I read the book, reviewed my …

In my access database, I have a table for the master list of items discussed in a training meeting. If a certain item was discussed in a meeting, then the value in the database is 1, if it was not discussed, then the item is 0. I'm trying to get these values into checkboxes on my form, checked if the value is 1 and unchecked if 0. However when I run it, I get a "NullReferenceException was unhandled. Object reference not set to an instance of an object" The code for that subroutine is: Private Sub NavigateTrainingItems() chkDrugAlcoholPolicy.Checked = False …

I am using PySide2 for GUI. I have a "Rename Project" QAction. The function must be like this: 1. set enable to false if tab name is "*Untitled" or file is unsaved. 2. set enable to True if file is loaded. How to do this? 3. Whenever switching to tab, these functions should be observed.

I have 30 functions like this void func1(int *var1, int *var2) { func2(var1, var2); } void func2(int *var1, int *var2) { func3(var1, var2); } void func3(int *var1, int *var2) { func4(var1, var2); } I do not need var3 until func15. Is there a way to fix this mistake without having to change all the function calls and headings? var3 needs to be remembered every time I get to func15. I only use var3 in func15 though so I really do not want to have to change all of my function calls and headings. It obviously can't be a local variable …

How can I make this to continue until the user presses N? I've tried using while(1), while( option == 'y' || option == 'Y') but it kept giving an error for that, and if/else statements but no luck. So I decided to try a do while statement and same results, it seems it is working, but I don't know what I'm doing wrong. I even tried moving all the statements to different areas and still nothing. #include <stdio.h> #include <time.h> #include <stdlib.h> enum meme {YEE, KNUCKLES, DOGE, HARAMBE, BUTKUS}; int dankestmemes(void); // function prototype int main(void) { srand(time(NULL)); // randomize …

I need a form that accepts two operands and an operator from the user and then performs the requested operation. Specifications Before performing the calculation, the application should check that both operands are numeric and that the operator is one of the following: + add - subtract * multiply / divide It should also check that both operands are between 0 and 1,000,000 (non-inclusive). To perform this data validation, code IsPresent, IsDecimal, and IsValidData methods as described in chapter 7 of the book. In addition, code an IsOperator method that checks for a valid operator.

This may sound wierd, or easy, I just don't have a statistics background. How do I alter the statistical value of an array of emmitted random numbers? I am completely capable of using ranges, or creating an algorithim, I just need pseudo code or a brief description to guide me through the process. This is not homework. This would mean I essentially generate randoms, and the final result has a statistical probability. Thanks!

Howdy All - I am just wondering if anyone has successfully converted a *massive* (subjectivity implied) COBOL application to another language. If so, into which language was your system converted and when was this done? What were the potholes you, no doubt, hit? Was the conversion far more expensive than anticipated? What hidden costs were exposed? Was there a performance gain/loss in the new language? Did anyone convert from COBOL to PL/SQL? to T-SQL? to Java? to C#.NET? Thanks, and have a great day!

If you have a counter that gets incremented through multiple functions, is it better to use a global counter or pointer counter? They both work just curious which is better and why.

The assignment states - A program that prints out lines of asterisks, based on the values determined by the user input. The program first asks for the minimum number of asterisks, the maximum number of asterisks, and the interval. It then prints lines of asterisks, starting with a line with the minimum number of asterisks, and ending with a line with the maximum number of asterisks. The increment of the numbers of asterisks is specified by the interval value. At the end …
