I am trying to seed a vector with 52 values ranging from 1 to 52. I already have the code written to seed the vector bu how to keep from repeating the same values from being seeded. This is for a five card stud game.
#include<iostream>
#include<cmath>
#include<cstdlib>
#include<string>
#include<vector>
#include<ctime>
using namespace std;

I am trying to write a sub-program that takes a deck of 52 cards and will shuffle it up using this algorithm:
Start with n=51
Repeatedly:
Generate a random integer between 0 and n. Call it i.
Swap card i and card n in the deck.
Decrease n by 1
However the code that I've written,
vector<int> shuffleDeck(vector<int> deckVector)//deckVector is the original deck in order
{
int temp, n, i, s;
n = 51;
[Code].....
when I output the new vector, only produces this output(note- it is a random number every time, but it just repeats over and over):
8 8 8 8 8 8 8 8 0 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8
8 8 8 8 8 8 8 8 8 8 8 8
or:
22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 0 22 22 22 22

I'm looking for a way to generate a program-wide unique value to use as a template parameter. Generating a unique value within a translation unit is pretty easy with __LINE__, but that doesn't ensure uniqueness across translation units. I thought maybe I could use __FILE__, but that can't be used as a template parameter.
I stumbled across this page: [uRL] ....
which is exactly what I want, except that the anonymous namespace trick doesn't work on all the compilers I've tried it on. (This may be due to C++11 changing anonymous namespaces to internal linkage rather than external as they did before....that page is five years old.)
I need to assign unique integer values to words in a dictionary that have the same alphabets, for example 'act' and 'cat' should have the same integer value. Would just adding the ascii values of the letters be sufficient?
View 1 Replies View RelatedI am grabbing data from three entities and want to grab a field value in each of the entites and place it in an arraylist. What I would like to do is loop through the arraylist for all the values and do something for each value only once. If the value in the array list is repeated, I want to not do anything for it and continue till the end. Basically, I loop through all the values do something for each value and skip over the repeated value if I already did something.

how can I write recursive function that creates a vector of every unique combination of commands?
I got this program to create an array of playing cards and assign the values and suits and shuffle the array. I'm at the point where I need to output the cards but I need to burn the first card by making it output "**" instead of the card. my cards[] is a constant so I can's assign the first card as such.
void showCards(const int cards[], int numCards, bool hideFirstCard) {
if (cards[0]) {
hideFirstCard=true;
cards[0] = '**';

Here is the code I have written so far. My problem is that when the second user enters its position the last user's position is wiped of the board. I want to know how I can hold that position and keep doing so until the game is finished. I thought that calling the previous function would do that (and you can see where I have put that into a comment) but it doesn't.

When things at work get overwhelming, it's not unusual for me to briefly "escape" by writing small programs simply for fun. A few days ago, I had an idea for a "binary game". I completed the first draft of it yesterday.
The idea is simple. The game uses 8-bit values. At the start of the game, a random "target" value is generated. The player is dealt a "hand" of seven values. The object is to use the values in your hand, along with some basic logical operations, to create the "target" value. While the idea is simple, the game itself can be quite difficult.
Here is an example of the output:
Code: --------------------
T: 1111 1100 (0xFC)
--------------------
0: 0000 0000 (0x00)
--------------------
1: 1100 1110 (0xCE)
2: 1010 0011 (0xA3)
3: 1100 0101 (0xC5)
4: 1011 1111 (0xBF)
5: 1010 1011 (0xAB)
6: 0001 1011 (0x1B)
7: 0001 1011 (0x1B)
--------------------
: Looking at the first column:
- 'T' is the "target" value
- '0' can be thought of as the "game board" - this is the value that needs to match the target value for a win
- '1' - '7' are the values in your "hand"
You can apply logic AND ('A'), OR ('O'), or XOR ('X') to a value in your hand with the value on the "game board". You are also allowed to apply logic to two values in your hand to create a new value for your hand. When a value from your hand is used, it is removed.
Some examples of the commands:
A30 --- apply logic AND to value #3 in your hand, and the "game board" value
O23 --- apply logic OR to value #2 in your hand and value #3 in your hand
X70 --- apply logic XOR to value #7 in your hand, and the "game board" value
You can also be dealt new values (as long as there's room in your hand) with the '+' command. 'H' or 'h' prints the help, and 'Q' or 'q' exits the game.
I haven't thoroughly tested it yet, since I just finished it a yesterday, but so far it looks good. The program itself uses only standard C.
I was dickering with the idea of supporting more logical operators (NOT, NAND, NOR, XNOR, shift), but I like the simplicity and resulting difficulty of the current implementation.
During initial testing, I realized it's possible to have doubles in your hand. Also, it's quite possible to be dealt the target value directly, which means that you could potentially win with one move, chance permitting. At first I thought about defending against these conditions, but came to the conclusion that it is fine as is - chances of an instant win are small, and if it does occur, would still be an enjoyable experience. Besides, if you're dealt the target value after the "game board" value has been modified.
Also, I did not allow a value of "zero" in the players hand. This was originally because I thought it would be of little use (though I've been reconsidering this). This also means that if two values in the hand are combined and result in zero, both values are removed and no new value is added. This was originally a bug, but I think I'll just reclassify it as a feature
So far, I found that the best strategy is to avoid modifying the "game board" value, and just play with the values in your hand. If you can get the target value in your hand, you just OR it with the "game board" and you're done.

I want to add this piece of code to a project. I have created a vector from values entered by a user. I want to then subtract each value from each other from the beginning to the end. For example if a user enters 10,4,3 the program will subtract the values in that order 10 - 4 - 3 and output 3 as the solution. I figured how to do it with addition but can't get it to output for subtraction.

Why does this generate an error:
Code: std::copy( vec.begin( ) , vec.end( ) , std::ostream_iterator<double>( " " , std::cout ) ); whereas this works fine:
Code: std::copy( vec.begin( ) , vec.end( ) , std::ostream_iterator<double>( std::cout , " " ) ); I know I can use this instead:
Code: for ( std::vector<double>::iterator it1 = vec.begin( ); it1 != vec.end( ); ++it1 ) std::cout << " " << *it1;
I am trying to assign a list of values to a vector:
vector<string> words;
words[] = {"one", "two", "three"};
This does not work. How can I accomplish it?
I wud like to delete multiple values from a vector using indexes as my values r not fixed they may change so using indexes i want to delete
For example: vector<int> v={1,2,3,4,5};
I want to erase 3,4,0 indexes
So resulting vector is 2,3
I'm trying to print values from a vector of a struct and I don't really know how to do that. Here is a simple code that I have for now to test how to add data to the vector then attempt to print it out.

#include <string>
#include <deque>
#include <fstream>
using namespace std;

I can`t seem to store multiple values into my vector when a user keys in an input. Lets say a user inputs 1,2 as the first set and later keys in 3,4.
My vector gets overridden by 3 and 4. I'm trying to pass these values into a function to store them into a vector and use them in the function.
Below is my code snippet
int reconstructSecret(int x, int y) {
int getX,getY;
getX=x;
getY=y;
vector<int> myXCordVec;
vector<int> myYCordVec;

I have a class that uses std::vector. I push back class objects onto the vector but when I try to cout the data members (with get functions) I get garbage values.
Here is the class:
#ifndef JOBS_H
#define JOBS_H
#include <iostream>
#include <iomanip>
#include <vector>
#include <string>
using namespace std;
class Jobs{
[Code] ....
I know I am missing the implementation of several functions but I'm just testing my vector to see if it is working and it isn't. The getBlockValue() function should output 0 for each job. When I push back one object the output is 0. When I push back 2 objects the output is 0. However when I push back 3 objects I get random values. Why is this? I thought vectors were dynamic?
I am writing a program to play rock paper scissors, and I am trying to get a vector to store the result of a given round of play, and output it as a declaration as to who won. I can't figure out how to store the values in the vector properly, and how to use the vector as an argument to output the result of play.
Code:
#include <iostream>
#include <iomanip>
#include <ctime>
#include <vector>
#include <cstdlib>
#include <string>
using namespace std;
const string name[4] = {" ", "rock", "paper", "scissors"};
const string roundResult[3] = {"computer win", "player win", "tie"};

I have two classes, one class requests another class to populate a vector with some data using getAvailableStreams() method:
vector<AutoRefPtr<ManifestStream> > availableStreams;
std::cout << "now asking for streams." << std::endl;
manifest->getAvailableStreams(&availableStreams);
std::cout << "got so many streams: " << availableStreams.size() << std::endl;
The other class passes another pre-populated vector back:
virtual RESULT getAvailableStreams(std::vector< AutoRefPtr<ManifestStream> >* availableStreams) {
availableStreams = static_cast<std::vector< AutoRefPtr<ManifestStream> >* >(myStreams); //myStreams contains 1 stream
I'm also adding a stream here directly just for testing purposes:
ManifestStream stream2;
availableStreams->push_back(AutoRefPtr<ManifestStream>(&stream2));
std::cout << "calling getAvailableStreams. Giving so many streams: " << myStreams->size() << ", " <<
availableStreams->size() << std::endl;
return result_OK;
}
If I run the code, I can see the following logs:
Now asking for streams. Calling getAvailableStreams.
Giving so many streams: 2, 2
got so many streams: 0
Why am I getting 0 streams when I exist the method? I just had 2 streams in availableStreams while I was inside the method, where have they disappeared?
I'm trying to increment the values in a vector, not the vector size, based on variable input. Basically I have a vector of size 10, and all of its values are initialized at zero. The program counts the frequency of numbers 0-9 in a four digit user input. This is what I have (I want it to work so badly but the compiler says that I'm using a pointer to a function used in arithmetic):
for (int i=0; i < num_slots; ++i) {
++guess_frequency[guess[i]];
}
I just want to know if you can increment values within a vector:
E.g.
change
0 0 0 0 0 0 0 0 0 0
to
1 0 0 0 2 0 0 1 0 0
I have a function that rotates a vector 90 degrees. Only problem is, i never get negative values. For some strange reason, no matter what i do, the value of x is positive. And even if the x is negative. Once i put it into direction (struct with 2 values x and y) it turns again to positive. Im using VSC++2013 ultimate. At first direction was SDL_Point, so i thought it was SDL problem, but now it seems its something else.
if (c == '-') {
int x = direction.y;
x *= -1;
int y = direction.x;
direction = { x, y };
}
I'm trying to get my program to read a series of comma delimited values from a file into a vector. However, I am unsure how to actually go about doing this. I've posted my best guess below but it's really just a stab in the dark and I always receive a compiler error.
Code:
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
using namespace std;
vector <string> v_input;
int main() {
ofstream fout ("Insert File Path Here.txt");
fout << "4, 8, 15, 16, 23, 42";

I'm still new at C++, so my syntax might be a little off for getting the correct output. Currently, there are no compiler errors or warnings, but there is also no output when I run the program. It seems as if it is not calling something correctly maybe the .toString or perhaps my DeckOfCards constructor is a little off, either way, I can't seem to figure out why there is no output.
