Thread: function not sending back values

Hey guys, I am trying to get all these functions work together and send the value of countX and countY back into main from function2() and function3() to be used by function4() later on.. But I keep getting 0 printed out and I am not quite sure why.. could anyone supply some ideas of how to fix this?

Code:

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


#define maxrow 20  //defines maxrow as a constant of 20
#define maxcol 30  //defines maxcol as a constant of 30


void function1(char array[][maxcol]);
int function2(char array[][maxcol]);
int function3(char array[][maxcol]);
void function4(int, int); //function to display the pairs count

int main( void )
{ 

int countX = 0;
int countY = 0;
srandom( (unsigned) time(NULL) );
char array[maxrow][maxcol];

function1(array);

function2(array);

function3(array);

function4 (countX, countY);

    return ( 0 ) ;

} 


void function1(char array[][maxcol])
	{
	int x = 0;
	int y = 0;

	 for (x=0;x<maxrow;x++)
	    {
    		 for (y=0;y<maxcol;y++)
       		    {
        		 array[x][y] = random() % 26 + 'A';
        		 printf("%c ", array[x][y]);
       		    }
   		 printf("\n");
   	    }
	printf("\n");
	}
int function2(char array[][maxcol])
	{
	int col = 0;
	int row = 0;
	int countX = 0;

	for (row=0;row<maxrow-1;row++)
        	{
         	for (col=0;col<maxcol; col++)
                   {
                	 if (array[row][col] == array[row+1][col])
                  	   {
                    	    countX++;
                   	   }
               	   }
       		 }
	return(countX);
	}
int function3(char array[][maxcol])
	{
	int col = 0;
	int row = 0;
	int countY = 0;

	for(col=0;col<maxcol-1;col++)
        {
         for (row=0;row<maxrow;row++)
                {
                 if (array[row][col] == array[row][col+1])
                   {
                    countY++;
                   }
                }
        }
	return(countY);
	}
void function4(int countX, int countY)
	{
	printf("\nNumber of horizontal pairs: %d\n", countX);
	printf("\nNumber of vertical pairs: %d\n\n", countY);
	
	}

You're not assigning the returned values to anything; e.g. you probably want countx = function2(array);
