funtions in arrays

[blaze745]

hey guys i gt this prac for campus plsss help here the question:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

You are going to write the memory game (with a deck of cards). Create an array of type integers,
with 52 positions. Each suit is represented by a set of 13 numbers. The first thirteen numbers are
Ace to King of hearts. The second thirteen numbers (14 to 26) are diamonds, the third set of thirteen
are spades, and the fourth set of thirteen is clubs.

Write the following functions:
· To initialize the array.

· A function that takes an individual integer and determines the number on the card.

· A function that shuffles the array.
o To shuffle the array, choose two random positions in the array and swap the values.

· A function that will appropriately display the number and suite of a single card.

Now create a parallel array of type Boolean that represents whether or not each card has been matched. Initialize the array to false. Write the following functions:

· A check function that checks if every value in the array is true, because this is the end game
condition.

· A display function, which displays the entire array (6 elements per line), with appropriate
numbering, so that a user can select two positions.

o If the position has been matched, display an ‘X’.

o Otherwise display a “?”.

Now you can write the memory game. While the end game condition is not met:
· Display the Boolean array.

· Read in a position number

o While the number at that position has been matched, ask for a different number

· Read in a second position number

o While the number at that position has been matched, ask for a different number

· If the value of the cards at each position is the same, set the values of the Boolean array to
true at both positions.

· Display appropriate messages for matches and misses.

my code so far

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

void Intialize(int arr[])
{
    for (int i = 0 ; i < 13 ; i++)
    {
        arr[i]= ( i +1);
        //cout<<arr[i];
    }
    //cout<<endl;
    for (int i = 0 ; i < 13 ; i++)
    {
        arr[i+13]= ( i +1);
        //cout<<arr[i];
    }
    //cout<<endl;
    for (int i = 0 ; i < 13 ; i++)
    {
        arr[i+26]= ( i +1);
        //cout<<arr[i];
    }
    //cout<<endl;
    for (int i = 0 ; i < 13 ; i++)
    {
        arr[i+39]= ( i +1);
        //cout<<arr[i];
    }


}

void ValueCard( int num)
{
    char CardLet;
    int CardVal;

    switch (num)

    {

        case 1:
        CardLet='A';
        cout<<CardLet;
        break;

        case 2:
        CardVal=2;
        cout<<CardVal;
        break;

        case 3:
        CardVal=3;
        cout<<CardVal;
        break;

        case 4:
        CardVal=4;
        cout<<CardVal;
        break;

        case 5:
        CardVal=5;
        cout<<CardVal;
        break;

        case 6:
        CardVal=6;
        cout<<CardVal;
        break;

        case 7:
        CardVal=7;
        cout<<CardVal;
        break;

        case 8:
        CardVal=8;
        cout<<CardVal;
        break;

        case 9:
        CardVal=9;
        cout<<CardVal;
        break;

        case 10:
        CardVal=10;
        cout<<CardVal;
        break;

        case 11:
        CardLet='J';
        cout<<CardLet;
        break;

        case 12:
        CardLet='Q';
        cout<<CardLet;
        break;

        case 13:
        CardLet='K';
        cout<<CardLet;
        break;



    }

}


void Shuffle(int arr[])
{
    //To shuffle the array, choose two random positions in the array and swap the values.
    int position_1 , position_2,temp;


        srand((unsigned)time(0));
        position_1 = (rand () % 52)   ;

        srand((unsigned)time(0));
        position_2 = (rand () % 52)   ;

        temp = position_1 ;
        arr[position_2] = arr[temp];

        temp = position_2;
        arr[position_1] = arr[temp];

}

int main()
{
    int arr[52] ;

    Intialize(arr);

    for(int i = 0 ; i < 52 ; i++)
    {
        Shuffle(arr) ;

    }

    for (int i = 0 ; i < 52 ; i++)
    {

        if( i % 13 == 0 )
        {
            cout<<endl;
        }

        ValueCard( arr[i])   ;



    }






    return 0;
}

If you were to point out somewhere specific where you are having a problem and type out grammatically correct sentences, the people on these forums will actually help you. Otherwise people on these forums might think you are just some winy, lazy programmer who can't even identify where the problems are in your code.

hey guys ok i need help to shuffle the array...it says to shuffle the arrray choose two random positions in the array and swap the values.

so heres my array

void Intialize(int arr[])
{
    for (int i = 0 ; i < 13 ; i++)
    {
        arr[i]= ( i +1);
        //cout<<arr[i];
    }
    //cout<<endl;
    for (int i = 0 ; i < 13 ; i++)
    {
        arr[i+13]= ( i +1);
        //cout<<arr[i];
    }
    //cout<<endl;
    for (int i = 0 ; i < 13 ; i++)
    {
        arr[i+26]= ( i +1);
        //cout<<arr[i];
    }
    //cout<<endl;
    for (int i = 0 ; i < 13 ; i++)
    {
        arr[i+39]= ( i +1);
        //cout<<arr[i];
    }


}

how do i shuffle it hmm??
