C :: Card Shuffling - How Numbers Are Not Repeated In Function
Jan 27, 2014
I found a card shuffling function on a long dead thread.
Code:
for (int x = 52; x > 0 ; x--)
{ y = rand() % x;
temp = deck[x];
deck[x] = deck[y];
deck[y] = temp; }
I do not understand how numbers are not repeated in the function. It seems like it would be possible to get 2 cards with the same number with the above function.
I also am getting incorrect numbers. It seems like I should only get numbers between 1 and 52 (which is what I want). However, I am getting the number 0, and some number between 1 and 52 will be missing, but I will have a total of 52 unique numbers.
I played around with using 51 instead of 52, x > 1, and changed to --x and none of those produced the desired results.
I want to calculate how many times the common number is repeated . So I have used freq[num] in that function. But I am getting the output like this-
Code:
The common number is = 5 The 5 repeated = 1 times The common number is = 6 The 6 repeated = 1 times
The common number is = 4 The 4 repeated = 1 times
The common number is = 5 The 5 repeated = 1 times
[code]....
So the freq[num] is only returning 1 instead of counting the total number of repeating which is wrong!! I would like to have somthing like this in my output -
Code:
The common number is = 5 The common number is = 6 The common number is = 4 The common number is = 5 The common number is = 5 The common number is = 8 The common number is = 9 The common number is = 6 The common number is = 6
So I already gave this a go and will post my code below. The question is about the last loop before the program cout's. i thought the count would keep track of the repeated numbers so i could display them but it does not. I italicized the loop i am referring to. or at least i tried to xD
#include <iostream> #include <iomanip> using namespace std; int main() { int inputs[30]; int numofloops; int maxvalue = inputs[0];
I'm writing a card game and I'm having trouble getting the first part of it right, which is picking out a random card from the deck and displaying it to screen. So it's supposed to display a different card every time i run the function in the program. The problem is, I keep getting the same output every time "Nine of Hearts".
This is what I have so far,
#include <iostream> using namespace std; //declare two string arrays //one holds the "suit" of the cards, the other hold the "value" string suit[] = {"Diamonds", "Hearts", "Spades", "Clubs"}; string faceValue[] = {"Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ace", "King", "Queen", "Jack"};
[Code] ......
This is the output I keep getting every time I run the program:
Nine of Hearts
This "random selection" function I'm trying to do is meant to work as a means of shuffling the cards in the beginning of every round in the game and displaying only the top card from the deck.
I'm currently on an exercise that specifies that I find any repeated words, "the the" for example, in a string, print the word that is repeated and how many times said word is repeated using a while loop that reads one word at a time and break statements when a repeated word is found. Having a bit of a falling out with iterators tonight and I'm not doing to well.
#include <cstdlib> #include <iostream> #define TRUE 1 #define FALSE 0 using namespace std; typedef int Bool;

Gives repeated digits in an integer but only in one condition : Only if the repeated digit is the result of n%10 where n is the integer the user writes. If the repeated digit is not the result of n%10 , then the compiler gives a wrong result.
so the question is : how to make this code gives the repeated digit in an integer (regardless the fact that the repeated digit is the result of n%10 or not and especially with making the minimum of changes on the code)????????? ?????
In the C++ book Programming: Principles and Practice Using C++, there's an example code like this for detecting repeated words:
Code: #include "std_lib_facilities.h" int main() { int number_of_words = 0; string previous = " "; // previous word; initialized to "not a word" string current; // current word while (cin >> current) // read a stream of words
[Code].....
The header file in there is sort of like a set of training-wheels for students who are complete beginners to the language; the function keep_window_open() is defined in there and it does just that on Windows systems where the output window closes too fast (in the case of the function, it's just like cin.ignore(), except it waits for you enter a character, like 'j', before it exits); programs on my Windows laptop work fine on Code::Blocks, but when I create a .exe file for them and double-click that file, it does actually close too quickly for me to be able to see the output (if it's a program like the generic "Hello World!" program that just outputs text to the screen and then exits - so all I see is the output window just flash-by really fast in those cases).
Anyway, as for the problem I'm having with the code: there are no error and compile- or link-time, but it does behave strangely at runtime, where the part inside the curly-braces of the while-loop doesn't execute at all.
I am working on a problem for the CS50 online course through the Harvard web site. I am trying to re-size a bmp image. They gave us a small program that copies a bmp image and we are to modify it to re-size the image. Here is the page [URL]..... Any way I am trying to move the file position indicator backwards so I can read the same line from the input file. So I can resize the file vertically I have the image resized horizontally but it keeps over writing the same lines vertically.

With out sorting and if the array size is changed and filled with different elements, mayb some that are all duplicates(in that case display message that says "No nonrepeated digits".
This seemed like a simple task but im failing to grasp some concept. if the array is 2,0,38,2,3,1,3 the first non repeated is 0. nested loop is how i went. i feel like im going to far with the counters than need be. just need first non repeated. if n equals 2 an o equals 0. and it iterates comparing 0,38,2,3,1,3 to n which is 2. repCount will b 1. if repcount was 0 then n would be the first non repeated number. im trying to consolidate my if else statements so there are not so many. This program fails if the array gets bigger say 2,45,2,7,1,8,9,45,1,10 .....
for (n=0; n<sizeof(digits)/sizeof(int); n++) { if(repCount<2) { // nonRepCount=0; for (o=n+1; o<sizeof(digits)/sizeof(int); o++)
I have generated a 10x10 integer matrix, by way of a 2 dimensional array, the elements are randomly generated and lie on 1 <= z <= 5. I am in need of an efficient method of setting all adjacent "duplicates" (repeating elements) of length 3 or greater to the integer six (6). The source for the brute method follows for clarity.
Read in n, then n lastnames, and check to see if the first in the list is ever repeated again.Here's what I have so far:
Code:
#include <stdio.h> #include <stdlib.h> int strcmp(char *w1, char *w2); int main() { int j, n; char string1[30], string2[30]; }
[code]....
I see the problem is that it lies within n amount of string that I am not going through every string to compare to the first one.How will do compare every string to the first one?
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.
and it wil output each word and maybe then can search for similar words if there would be 2 strings then i would use strstr but i dont know how to do with one string.
The deck of cards so it is populated with all 52 cards. Once you have populated the deck, you need to shuffle the deck. Here is a simple algorithm you might consider for this purpose:
For each card up to the middle of the deck generate a random number modulus the size of the deck, swap the current card with the card at that location done
To implement this requirement you need to implement and use the following functions:
i was reading trying to get it how to display the out put, all i got to is how to declare the arrays. How to start it also i saw some examples have " struct card"
I have to develop an application named smart client score board in c#
Main requirements for this application are that application should display the live scores, detailed score board, running commentary (in text), players and team profiles, statistics of matches, results and fixtures for cricket.
sort out websites which support rss feeds for full score card.
I'm working on a game with an entity-component system. I have a Manager class that is handling all of the components by feeding them into vectors set up for each type of component. Right now I have a lot of repeated code for each kind of component.
I've tried generalizing this with templates, but I've been confused by how I should organize the collection of vectors for each component. I had it setup so that they were all in an unordered_map, but how to get the templated functions to find the right map slot to use based simply on the template's parameters.

I want to get or view the SIM card number from the dongle (the dongle will b already connected to the computer where the SIM card will be inserted into it) but the coding should be done by C programming / Language.
We have to ask the user to select either a Visa card type or Mastercard type. Then, we must ask the user to enter the 16 digit card number and determine if the card is valid or not using module 10. If the answer is zero then it is a valid Visa card and if the answer is zero the answer is a valid MasterCard. My problem is that the I have not separated the validation for MasterCard separate from visa.
Here is what I have so far:
#include <iostream> #include <iomanip> #include <string> using namespace std; int main() {
I almost finished a program but am stuck on sorting the hand im dealing with qsort. sorting by the face values and if they have the same faces im suppose to follow this suit order to determine which one is greater (Clubs, Diamond, Hearts, and Spades) how would i adjust my comparator function to do this for me ?
