Thread: Counting Elements in an Array

Hey guys, I have an array or [21]rows and [19]cols. Each row and column have the numbers -1,0,1 scattered randomly throughout the array from what was a medianmap. Now i want to calculate the counts for each respective column and row for 1,0,-1. I have written the code although it wont output correctly, below is the code followed by the print statement.

your help would be appreciated.

Code:

/* Declare any constants */
/* Input file name */
#define FILE_NAME "data-5.csv"
/* Data size */
#define MAX_COLS 19
#define MAX_ROWS 21
/* Map symbols */
#define MIN_SYM  -1
#define MAX_SYM  1
#define MIDDLE_SYM  0
/* Use to reference the counts */
#define MIN_SYM_INDEX  0
#define MAX_SYM_INDEX  1
#define MIDDLE_SYM_INDEX  2
#define MAX_COUNTS  3

/* Declare any variables */
/* Used to hold the index of the row/col that is the middle value */
    int MedianIndex1 = 0;
    /* Used to hold the index of the row/col when there is an even number of rows/cols */
    int MedianIndex2 = 0;

/* Initialise the variable arrays */
    for (row=0; row < MAX_ROWS; row++) ;
    {
        RowMedian[row] = 0;
        RowCounts[row][0] = 0;
        RowCounts[row][1] = 0;
        RowCounts[row][2] = 0;
    }
    for (col=0; col < MAX_COLS; col++) ;
    {
        ColMedian[col] = 0;
        ColCounts[col][0] = 0;
        ColCounts[col][1] = 0;
        ColCounts[col][2] = 0;
    }

Code:

/* Get Counts */
    /* Determine Counts for the rows */
    for(row = 0; row < MAX_ROWS; row++)
    {
        for(col = 0; col < MAX_COLS; col++)
        {
            if(MedianMap[row][col] == MIN_SYM)
            {
                RowCounts[row][MIN_SYM_INDEX] = (RowCounts[row][MIN_SYM_INDEX] + 1);
            }
            else if (MedianMap[row][col] == MAX_SYM)
            {
                RowCounts[row][1] = (RowCounts[row][1] + 1);
            }
            else
            {
                RowCounts[row][2] = (RowCounts[row][2] + 1);
            }
        }
    }
    
    /* determine counts for the cols */
    for (col = 0; col < MAX_COLS; col++)
    {
    for (row = 0; row < MAX_ROWS; row++)
        {
            if (MedianMap[row][col] == MIN_SYM)
            {
                ColCounts[col][MIN_SYM_INDEX] = (ColCounts[col][MIN_SYM_INDEX] + 1);
            }
            else if (MedianMap[row][col] == MAX_SYM)
            {
                ColCounts[col][MAX_SYM_INDEX] = (ColCounts[col][MAX_SYM_INDEX] + 1);
            }
            else 
            {
                ColCounts[col][MIDDLE_SYM_INDEX] = (ColCounts[col][MIDDLE_SYM_INDEX] + 1);
            }
        }
    }

print statement.

Code:

printf("RowCounts\n");
    for (row = 0; row < MAX_ROWS; row++)
    {
        printf("%f", RowCounts[col][MIN_SYM_INDEX]);
        printf("%f", RowCounts[col][MAX_SYM_INDEX]);
        printf("%f", RowCounts[col][MIDDLE_SYM_INDEX]);
    } 

    printf("ColCounts\n");
    for (col = 0; col < MAX_COLS; col++)
    {
        printf("%f", ColCounts[col][MIN_SYM_INDEX]);
        printf("%f", ColCounts[col][MAX_SYM_INDEX]);
        printf("%f", ColCounts[col][MIDDLE_SYM_INDEX]);
    }
