C++ :: Randomizing Array Without Repetition?
Oct 4, 2014I just want to make a WORD GUESSING GAME which when you play it and got the correct word will ask you to play again then it will automatically randomized the words in the array list.. then when you play the game, the words will not repeat until you played them all then it will stop.

C++ :: Make A Function To Return Placement Number
Mar 25, 2014I have a class called items and stored in a vector as vector<items*> item.now I want to make a function to return the placement # that the item is stored at with a unsigned int. but if I don't find the item is there like a null unsigned int that can be returned.
unsigned int someFunc(vector<items*> item)
{
unsigned int size = item.size();
for (unsigned int i = 0; i < size; ++i)
{
if (item[i]->getItemName() == "sword")
{
return i;
}
}
//i need code here incase the item is not there
}
because the item might not be there and i would like to do a line if(unsigned int) do this code
C++ :: Randomizing Set Of Strings In Structure
Apr 16, 2014I currently have a structure that contains strings.
What I would like to do is randomize these strings so that for example the user picks an input, one of these strings will display.
Is it possible to do with the rand function or do I have to go about creating my own functing, assigning values to these strings somehow etc. etc.
I tried reading up on it but as far as I could realize you could only use rand () with numbers, set values etc.
Code:
struct sample_a
{
string mot1 = "heej";
string mot2 = "haj";
};

C++ :: Randomizing Order Of If-else Statements
Dec 11, 2013The purpose of doing this is so that the top of the if statements is not preferred over the bottom. I tried assigning enum values to each case. Then choose a random integer r from 0 to the size of the std::list myList containing those enum elements. The enum value is found using it = std::next (myList, r). Then if the if statement corresponding to that enum value is false, then myList.erase (it), and repeat the process with the newly reduce myList. It works, and everything seems nicely randomized. But it is disappointing much slower than when I used the original if-else statements (it is being applied hundreds of times).
Here is a snippet of my code (I decided not to use switch statements because it looked too clumsy):
std::list<FacingDirection> guyFacingDirections = {Positive_x, Negative_x, Positive_y, Negative_y, Positive_xPositive_y, Positive_xNegative_y, Negative_xPositive_y, Negative_xNegative_y};
while (true) {
const int r = rand() % guyFacingDirections.size();
[Code] .....
There is a crowd of girls. Each guy will choose a girl, and then choose a facing direction to dance with his chosen girl. But not all facing directions are possible if someone is standing at the spot he wants to stand at to get his desired facing direction. Without randomizing the if-else statements, most of the guys will end up facing the same direction, which I don't like.
C/C++ :: Taking String As Input And Making It As Whole Array (string Literal)

C++ :: Input String Text Into String Array
Jun 26, 2014/*assume array is already initialized and declared and is of array type string.*/
int i = 2;

I'm having lots of trouble with storing a cin string text into a string array. It just seem that after I cin newvalue, the program crashes. Is this way of storing it considered illegal? I'm just a beginner with 5 months of coding experience in C++.
C++ :: Char Array To String - String Becomes Garbage
Apr 20, 2013I'm trying to "tokenize" a string using std::string functions, but I stored the text in a char array. When I try to convert it to a string, the string has the first character right but the rest is garbage.

C/C++ :: Enter String Into String Array Via Cin Or Getline
Mar 29, 2014Ok so I searched this site, and google string arrays, but I couldn't find anything on how to create an array to accept string input. In other words the strings are unknown, until the user inputs them..
so code would say input a name..user enters Tom, and its inserted into the array.. and if another name is entered ..lets say Lisa..Lisa is added to the array..so now in the array we have tom and Lisa..
Everything I read only shows the array already having the strings declared...
string n;
string name[n]={};

C++ :: Changing Array Of Characters To A String Array?
Apr 7, 2013I have an array titled: char TypeOfSong[arraySize] where the array size is 15. I am reading data from a file into this array and the characters can be either 'C', 'D', 'E', or 'R'. Each of these characters stands for a word (sting) and when I output the array, I need the strings to show up, not the characters. I have been reading online and in my book but I can only find information on turning one array with the same characters into a string. How would I go about changing this character array with different characters into a sting?
The characters stand for:
C = Country
D = Dance Party
E = Elevator
R = Rock

C++ :: Char Array To String
Oct 19, 2013I have some code:
char cHomeTeamFaceOffsPercentageWon[100];
memcpy(cHomeTeamFaceOffsPercentageWon,cSqlHomeTeamFaceOffsPercentageWon,100);
After this, for example, cHomeTeamFaceOffsPercentageWon is, "29%".
Then, I use
std::string szwPercentageWon = std::string(cHomeTeamFaceOffsPercentageWon);
szwPercentageWon is then, "2". Shouldn't this convert correctly, to "29%" as well.
Or is there something I'm missing? Maybe the termination character, or something.

string int2string();
The error is due to variable type does not match. Is there a better way to convert int array to string?

Point[1] (x2,y2) and so on.

C++ :: Length Of String Array?
Sep 7, 2013I can't find any method of retrieving the length of an array except for doing this:
string first[] = {"a","be","see"};
int length = sizeof(first)/sizeof(first[0])
This is a very unconventional way of getting the length of an array.
first->length() would return 1 because it returns the number of letters in the first element of the array (which actually makes no logical sense).
first.size() would return 1 aswell as it's practically the same thing.
Since getting the length of an array is such a fundamental feat, how come I can't find a decent method of doing it?
Is there no buildt in method for this? If there is not, why has it not been implemented in the std?
