C++ :: Loop Through Indexes In Guess Array And Assign M Randomly
Jan 19, 2013Just run a loop through each of the indexes in the guessarray and assign 'M' to them randomly.

View 2 RepliesBasically I have a text file called words. I'm supposed to extract a word randomly form the file and have the user guess the word. If they guess the word correctly in x number of tries they will receive the definition.
I'm having trouble receiving that random word and I'm getting the definitions from the file.
Here's my code:
#include <iostream>
#include <fstream>
#include <string>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
using namespace std;
[Code] ....
This is what is in the words.txt file
apple#the usually round, red or yellow, edible fruit of a small tree
boat#a vessel for transport by water
horse#a solid-hoofed plant-eating domesticated mammal with a flowing mane and tail, used for riding
television#a system for transmitting visual images and sound that are reproduced on screens
soup#a liquid dish, typically made by boiling meat, fish, or vegetables, etc.
bottle#a container, typically made of glass or plastic and with a narrow neck
barber#a person who cuts hair
toast#sliced bread browned on both sides by exposure to radiant heat
radar#a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects
red#of a color at the end of the spectrum next to orange and opposite violet
Write a C++ program that uses a while loop to guess a persons age, ask the user if the want to try again if no end the loop. Of course if they guess it the loop also ends

View 2 Replies View RelatedSo I have a vector that I want to iterate through randomly, and by random I mean that each element is only accessed once but I don't want to shuffle the vector because the vector elements are large. So I want this functionality:
std::vector<SomeLargeObjectWithoutACopyConstructor> myvec;
// ...fill myvec
std::random_shuffle(myvec.begin(),myvec.end());
for (auto& value : myvec)
{
// do stuff
}
Only I don't want to do this because the object type has no copy constructor and is large, so I don't want to shuffle the vector, just the iteration path. Is there a simple and efficient way of iterating randomly through a vector while ensuring that each object is only accessed once?
Is it possible to loop randomly. For example
for ( int i = 0; i<= 6 ; i++ )
I don't want i to acsend from 0 to 6 but i want it to get all numbers randomly. For example
first time r = 5 second time r = 2 and so on
until it gets all the seven numbers
For an assignment I have to create a random array of four integers, and then I have to allow someone to input up to ten guesses to guess the array in the correct order. I also need to be able to display whatever was generated by inputting -1. Finally, after every guess I have to tell the inputter how many of the guessed integers are correct and in the correct position, as well as how many integers are correct but not in the correct position.
So far I've been able to get the random array to generate properly, but inputting negative one has no effect, although if I input it four times in a row I get to my 'lose' condition. Also, it only seems to allow the user to input 4 guesses and not 10 before going straight to the 'lose' condition. I need to get these issues sorted out before I can move on to showing how many guesses are right etc....
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main()
{
srand(time (NULL));

I wrote this code but it opens file in its folder Iwant to save in somewhere else. How I could assign path for the files in for loop?
for (double j = 0.5; j < 1.4; j+=0.1) {
s +=1;
stringstream a;
a << j;
filename = "Vzcr_" + a.str();
filename += ".txt";
files.open(filename.c_str(), ios::out);
Ok here I have a program that reads a word from a text file randomly and matches it with the definition. The user has to guess what the word is according to the definition.
I'm having trouble with my for loop, I'm not getting any errors. But I just know something is off.
Here's my code:
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
#include <ctime>
using namespace std;
int main(){
int number;
int count = 0;
int numOfGuess = 0;

I am very much a beginner at C and a large amount of it still tends to go over my head, I've created a 2d array which its size is generated from user input and filled with random integers. Next I need to locate the maximum and minimum figures in the integer and as dull..This is the code I have so far
Code:
#include <stdio.h>#include <stdlib.h>
int main ()
{
int firstDimension, secondDimension, firstDimensionIndex, secondDimensionIndex,index;

I was wondering if there was a way to set up a code with an array of variable dimensions that removed random points on that array i.e.
1111
1111
1111
then randomly remove a point:
1101
1111
1111
and then be able to repeat this process until all points are removed.
I am trying to select 3 questions randomly from a string array and create another array with the randomly selected questions then display them in labels.
As you can see in the code I have used Array.Clear method to remove the selected question from the array to prevent duplicate questions being selected. For some reason this is not working! The "Randomly" selected question is ALWAYS the 5th element [4] of the randomQuestions array and this element is duplicated for each iteration of the loop.
public void shuffleQuestions() {
string questionselected;
string[] randomQuestions = {
"What is the speed limit from the time you pass an Accident sign until you have passed the crash site?",
"What must you do at a red traffic light?",
"What is the maximum possible speed limit on the open road?",

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] = '**';
} for(int a = 0; a <= numCards; a++) {
cout >> showCard(cards[a]);
} }
Write a program using user-defined function which accepts an integer array and its size as arguments and assign the elements into a two dimensional array of integers in the following format: If the array is 1,2,3,4,5,6, the resultant 2D array is

Why would you ever assign a pointer to an existing array?Take this link for example. URL....I understand that pointers use dynamic memory allocation so they are much more flexible then a built in array, but if you already have an existing array, don't you already have static memory allocation for that array? Why bother assigning a pointer? Regardless of the pointer, doesn't the program still allocate static memory to the array anyway?
View 3 Replies View RelatedHow to assign numbers stored in a buffer memory to a 2D array.
The data type is unsigned 16bit (unsigned short) integers and they are stored in a 16bit/2bytes*1280*1024=2621440 bytes memory. The pointer pBuffer is the starting address of the buffer. Now I initiated an array and then assign the numbers to the array.
Code:
unsigned frame[1280][1024];
for (int i=0;i<1024;i++){
for(int j=0;j<1280;j++){
frame[i][j]=(*(unsigned short*)pBuffer+1024*i+j);
printf("%u ", frame[i][j]);
}
printf("
");
}
Because I know the number in the memory, I know after running the code that the result gives me nonsense.
I tried frame[i][j]=(*(unsigned short*)pBuffer+1024*2*i+2*j);
Since I think the pointer needs to move 2 bytes at a time, but it still gives me nonsensical array back.
Am I using the wrong expression to assign the values?

I have a 3x3x3 matrix with values hanging from 1 to 27.
The order is this: Code: m[0][0][0] = 1;
m[0][0][1] = 2;

m[0][1][0] = 4;
m[0][1][1] = 5;

Is there an easy way to compute the indexes given the value? For example, I know that the first index can be found by dividing the value by 9.0: Code: const int firstIndex = ceil(value / 9.0) - 1; What about the second and the third indexes? I couldn't find a pattern in the numbers, and I didn't want to iterate through the matrix (the indexes will be calculated many times).
The other option is to create arrays where the values will be indexes and the matrix indexes will be the values. I'm not sure if it is the best way though
I can assign values to pointer character array like this...

I have been given an assignment which I understand pretty well, but I have a problem, and haven't been able to find a clear solution anywhere. I'm sort of a beginner in all this, so it's hard to understand what some people say.
So basically what I wanna do is assign a set of grades to every element in an array of a set number of students. I already have the part where you ask for the number of students you want to enter and then ask for their names and grades, but it can only enter one grade, and I can't figure out how to assign several grades and then get the average.
Here's my code, the assignment said to do it like this.
#define MAX 100

Trying to get table indexes information in SQL Server 2012 I identified a strange situation for one scenarion.I have a table that contains two indexes referenced to some fields: Field_1 and Field_3 mapped over int, null columns (the number means the existing field order into the table designed few years ago...).
I am trying to get information about these indexes like this:
Code:
nRetCode = ::SQLStatistics(hstmtAux, NULL, 0, NULL, 0, (TCHAR*)(LPCTSTR)strTempTable, SQL_NTS, SQL_INDEX_ALL, SQL_ENSURE);
if (nRetCode == SQL_SUCCESS || nRetCode == SQL_SUCCESS_WITH_INFO)
{
nRetCode = ::SQLBindCol(hstmtAux, 4, SQL_C_SHORT, &swNonUnique, sizeof(SWORD), &cbNonUnique);
nRetCode = ::SQLBindCol(hstmtAux, 5, SQL_CHAR, szIdxQualif, sizeof(CHAR) * 130, &cbIdxQualif);
nRetCode = ::SQLBindCol(hstmtAux, 6, SQL_C_CHAR, szIdxName, sizeof(CHAR) * 130, &cbIdxName);
nRetCode = ::SQLBindCol(hstmtAux, 7, SQL_C_SHORT, &swType, sizeof(SWORD), &cbType);
nRetCode = ::SQLBindCol(hstmtAux, 8, SQL_C_SHORT, &swSeqInIdx, sizeof(SWORD), &cbSeqInIdx);
nRetCode = ::SQLBindCol(hstmtAux, 9, SQL_C_CHAR, szIdxColName, sizeof(CHAR) * 130, &cbIdxColName);

Becasuse SQLExtendedFetch() is deprecated I used SQLFetchScroll() but the behavior is the same from my interest point of view.
Usally, I get the right information about indexes but in one situation I encounte a strange behavior. It's about having a clustered index into a scenario.
When Field_1 is Non-Unique, Non-Clustered and Field_3 is Clusted index I get the right information.
But if the index Field_1 is Clustered and the Field_3 is Non-Unique, Non-Clustered I get no information about Field_1 index (eg. szIdxName and szIdxColName are "" and their length is -1 that means SQL_NULL_DATA). So, I have no Index information. Within while loop, with the next iteration I get correct information about the second index Field_3.
I'm not sure whether the problem is with SQLStatistics, the bindings or SQLFetchScroll (they all always return SQL_SUCCESS). It looks like a problem with the driver when the first index is clustered.
STRING s1 = “FOOBAR”
Here STRING is a user defined class. how to assign a constant char array "FOOBAR" to string object? Copy constructor need to be same class type as parameter. and overloading assignment operator also need to be same class type. I think 'friend' can let pass another type of object rather than STRING to do operation on overloaded '=' operator. How could it be done if it is possible at all?
