Selecting and marking a value on an array

[LonelyGuy Sylar]

I'm currently having difficulties on selecting and marking a value that had been on selected on a 2d array.


Example: Before selecting the value the array should look like this.

# # # # # # # # # # # #
#  1         2        #
#               4     #
#  6     2        8   #
#                     #
#       1   3    5    #
#                     #
#   3          6      #
#         4       5   #
#     7               #
#          7     8    #
# # # # # # # # # # # #

Example:After Selecting the value the array should look like this, assume the user select number 1 as the value.

# # # # # # # # # # # #
#  [1]   9   2        #
#               4     #
#  6     2        8   #
#                     #
#       1   3    5    #
#                     #
#   3          6      #
#         4       5   #
#  9  7               #
#          7     8    #
# # # # # # # # # # # #

My current code:

#include<stdio.h>
#include<stdlib.h>
#include <time.h>


void print_array(int arr[12][12], int ar[144]){


int i,j,m=0;


for(i=0;i<38;i++)
{
    printf("#");
}
printf("\n");
 for(i=0;i<12;i++) 
    {
            for(j=0;j<14;j++)
            {
                if(j==0)
                {
                    printf("#");
                }
                else if(j==13)
                {
                    printf("#");
                }
                else
                {
            
                    arr[i][j-1] = ar[m++];
                        if(arr[i][j-1] == 0)
                        {
                            printf("   ");
                        }
                        else
                        {
                            printf(" %d " , arr[i][j-1]);
                        }
                }                    
             }
        printf("\n");
    }
    for(i=0;i<38;i++)
{
    printf("#");
}
printf("\n");
}






void shuffle(int arr[12][12], int ar[144]){


int t,j,i;


     srand ( time(NULL) );
    for(i=144-1;i>0;i--)     
    {
        
         j=rand() % (i+1);
         t=ar[j];
         ar[j] = ar[i];
         ar[i] = t;
    }






}




//error the whole selectnumber seems to have problem
void selectnumber(int arr[12][12], int ar[144], int *num, int *x, int *y)
{
int i, j, test=0;
int temp;
printf("please select a number from 1-8:\n");
fflush(stdin);
scanf("%d", &temp);


arr[*y][*x]=' ';
arr[*y+1][*x]=' ';


for (j=0; j<=12; j++)
{
    for (i=0; i<=12; i++)
    {
        if(arr[j][i]==temp && test==0)
        {
        *y = j;
        *x = i;
        test = 1;
        }
    }
}


arr[*y][*x]='-';
arr[*y+1][*x]='-';


*num=temp;


}






int main()
{
    int array[12][12]={0};
    int randvalues[144]={1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8};
    int gx,gy;
    int ginput;
    
  


    shuffle(array,randvalues);
    print_array(array,randvalues);


    selectnumber(array, randvalues, &ginput, &gy, &gx);
    
 


    return 0;
}

Since my array consist two types of array therefore i'm very confused on how to do it, please kindly help me

I think it's just a matter of finding the temp number they chose in this part in the 2d-array:

printf("please select a number from 1-8:\n");
fflush(stdin);
scanf("%d", &temp);

And displaying it with printf("[%d]", arr[y][x]); or something similar.

Did you know that fflush(stdin); may not work?

hmmm correct me if i'm wrong..
your method seems like getting the user to input the number and display it on an array, right?
what i'm trying to achieve is, when the user enter a number, the program will find the value which is already in the array.
since i'm having a function of printing the entire array, i cant print the array in selectnumber function

[whiteflags]

The select number needs to find the temp number in the array... so somewhere a comparison like temp == arr[y][x] should be true, and then you print the arr[y][x] in the manner I showed.

[LonelyGuy Sylar]

i'm currently blank and blur.. have no idea on how to do it =(

[whiteflags]

OK, then simplify first until you get the idea. Pretend that the number is 1. Your task is to call printf("[%d]", arr[y][x]); when you first find 1 in arr. When you can do that, the next step is to make it work for the number called temp.

[LonelyGuy Sylar]

okay mate, i'll think about it.
