C# :: How To Store Multiple Function Calls In Array
Oct 9, 2014
My function "MatrixMul" returns an int array with multiple values Let's say, res[0] and res[1]
When I'm calling the array in a for loop for multiple times, and when I'm storing the results in another array, in each iteration the results are over-written with the new results.
If the first call returns [0,1] the array will store [0,1] at index [0] and [1], which is fine, but when I'm calling the function again, the new results are stored at the same indexes [0] and [1] How can I avoid that?
The code is:
class Hill_Cipher
{
string AtoZ="ABCDEFGHIJKLMNOPQRSTUVWXYZ";
public string Hill_Cipher_Enc(string input, int[,] key)
[Code].....
For example, my outPut contains the following: "TH","IS","AT" when I'm calling the function with the first element of array "TH", it converts "T" to its equivalent number and apply some calculations and same with "H". Let's say the final answer is 20 for "T" and 30 for "H". The problem is that every time, encChars will store the values at index 0 and 1: encChars[0]=20 encChars[1]=30 When I call the function again it will store the new values at 0 and 1.... That's because I'm not changing the index value for encChars on each call, so how do I do that?
what happens with newheaderstr every time malloc() is called. There isn't a realloc() or anything. I didn't think it looked right to keep using malloc() like that.
I am just trying to make a simple two player game. First player enters the movie and second player guesses it by using some basics of C++.
movie[] = entered by player 1. movie_temp[]= a temp array with '_' in it. It updates after every guess by player 2.
MY PROBLEM: Please refer the main function where I called the function movie_check().
This updates the life after every guess. I want the same to happen for my movie_temp array.
When i run this program, only the lives are updated properly, on correct guess the lives are not reduced, but in next turn the array_temp is not updated and the same array is displayed again and again after each gas.
How to create a function which return array and save it in movie_temp (just as I did for life).
In class, we have learned how to set up the main method so we can convert command line arguments to integers and utilize them. Here is an example of a method we learned to store command line arguments as integers in an array:
Code: int main (int argc, constchar* argv[]) {int i; int a[argc - 1]; // Fill the array with the arguments on the command line for (i = 0; i < argc - 1; i++){ a[i] = atoi(argv[i + 1]);
[Code] .....
I understand that there are probably better ways to do it than using the atoi function, but for our purposes, the professor said this was okay.
Now, I am being asked to create a separate function to perform the same task (store integers in an array). I was told I would need to declare the array "out in the main program", and that the function would need to take at least 2 arguments: an array, and an array size.
Firstly, what should my return value be? My professor gave a hint that it would be important for me to figure out what the return value is, but I don't see why it would be anything else than void.
Also, wouldn't I need a third parameter? Perhaps the integers that are being stored in the array? (But how would I represent this as a parameter)?
I am working on a text based RPG. As with most RPGs the character has attributes that grant modifiers. Lets take strength for instance. Suppose the character can have a strength score that ranges from 1 to 10. Based on strength the modifiers could be like the following:
Strength = 1 grants +1 to hit and +1 damage Strength = 2 grants +1 to hit and +2 damage Strength = 3 grants +2 to hit and +3 damage
I want to set these values at design time and be able to retrieve the modifiers based on the strength value from multiple places in my program.
What is the best method of designing this. I looked around online and saw references to Lists with Tuples and Dictionaries with Tuples but these did not seem to be a very efficient way of handling the scenario above.
Write a program using inheritance allow user to enter grades of his students 5~8 students as a base class and compute the sums for each students in derived class and compute the average of sums in another derived class. I created 3 classes in 1 header file and 1 cpp file how ever i cant seem to get the sum or the average to show up on execution time
Are the objects in both vectors the same instance of the object? Like if I called vectorOne[0].setValue(somethingDifferent); would the value be changed for the object in both vectorOne and vectorTwo? If not, how do I make sure that I only have one instance of the object I'm trying to store in multiple vectors?
am trying to create a program that asks the user personal questions.
std::vector<std::string> name, age, favsinger; std::cout << "Hello, what is your Name Age Favorite_Singer? "; std::cin << name; //i want to store the user's info along with the sibling's
It seem to store the entire line in userID including the ":". I want to ignore the ":"'s and store everything in between in respective varibles in the order specified above.
So first string in userID, then ignore the :, then second string in name, and ignore the next :, and so forth.

I am trying to write a menu program that will be broken down into a series of calls to function for each of the menu items. Two of the menu items will be simple programs which I wrote.
I want two of the functions to run one of the two programs I am trying to include as items in the menu.
So far I am only familiar with variables, loops, if statements, and I just learned how to write functions.
The problem I am have is that I don't quite understand how to write a function that will run one of the two programs. Also I am having a hard time writing the program in away that would allow the user to select the menu items.
I have a multi-thred piece of code that should be fast. As I have to update a Database from time to time, I wonder if I do it in a prpoer manner with calls like this:
Those are my sporadic updates, my ongoing update have a queue and a dispatcher thread reading from the Q, I just don't want to use this overhead for the sporadic updates.
The program should store a character array in reverse order then display the reversed array. I have also included in the code that will display the actual characters into the array as it loops through. So I know the characters are being stored, but why doesn't it display the entire string when I call it?
Now the recursion will generate a large recursion tree, like if n=5, 5 will call (5-1), (5-2) or 4,3 . What I want to know is, will fibo(n-1) will be called 1st go all the way to the base case 1, then do the summation or fibo(n-2) will be called right after fibo(n-1) ?
Let's start with something from the c++ reference:
... delete[] is an operator with a very specific behavior: An expression with the delete[] operator, first calls the appropriate destructors for each element in the array (if these are of a class type) ...
I was wondering if I can tell delete[] to not call destructors, for example if I already know that the delete[] statement should be delete without []. That would be very useful for memory management/memory leak detection.
I have several functions doing similar things, inside their implementations, the parameters are the same, but they call different methods.
I want to create one function to make the structure easier, and reduce the duplication. I heard template might be one solution. But I am not sure how to use it in this case.
I'm trying to implement a code that recursively calls itself and prints the given digits in ascending order, i.e. if the number is 5, then the function will print 1 2 3 4 5. I cannot use loops in any way!
The problem I have is with keeping my variable i at a set value each time the function calls itself.
void print_ascending(int n){ int i = 1; if(i < n) { printf("%d", i); i++; print_ascending(n); } }
Of course, the problem with this code is it will re-initialize the variable i to 1 every single time and infinitely loop to print 1.
1: Sort Alphabetically 2: Sort Grades Increasing Order (Student) 3: Sort Grades Increasing Order (Project) 4: End Program Enter choice:
Why my sort is not working. Also, I want to keep the same random numbers for the continuation of the program, I don't want new randomized values when I display the table.
I need to be able to disable the items on a CCheckListBox but I can't change the code that calls AddString. I know I can use the CCheckListBox::Enable function to disable an item if I have an index but I don't have the index which would be provided by AddString.
I've tried intercepting the LB_ADDSTRING message and then looping through the items in the control but the string has not been added at this point so the last item in the list is never disabled.
I used Spy++ to see what messages were being sent and I noticed that LB_GETTEXT was sent so I tried intercepting this message (ugly hack) but this caused my app to hang - I assume because of the number of times the message is sent. Is there a way to disable the items?
