Thread: reading from a 2d array

I have a 2d array of characters and now i am trying to read from it and writing to a file. The thing is that the file seems to get created but there is nothing in it. Please let me know where i am going wrong


[insert]

Code:

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

#define MAX_WORD_LENGTH 31
#define MAX_WORDS 50

/* Function prototypes */
int readFile(char* inputFileName, int* wordCount, char array[][MAX_WORD_LENGTH], int flag);
//int qsort(char array[][MAX_WORD_LENGTH], int* wordCount);
int writeToFile(char* outFileName, int wordCount, char array[][MAX_WORD_LENGTH]);
//void printTime(time_t  begin);
void usage(char* processName);
// enter any other function prototype you may wish

int main(int argc, char* argv[])
{
		char array[MAX_WORDS][MAX_WORD_LENGTH];

		int wordCount = 0; 
		
       	switch (argc)
		{
		case 3:
			readFile(argv[1], &wordCount, array,0);
			writeToFile(argv[2], wordCount, array);
			break;
		case 4:
		{
			if (strcmp(argv[1], "-s") == 0)
			  {
			   readFile(argv[2], &wordCount, array,1);
     		   writeToFile(argv[3], wordCount, array);
			  }
			else if (strcmp(argv[1], "-t") == 0)
			  {
			    readFile(argv[2], &wordCount, array, 2);
			    writeToFile(argv[3], wordCount, array);
			  }
			else
			  {
			    usage(argv[0]);
			  }
			break;
		}
		case 5:
		default:
	        usage(argv[0]);
	        break;

		
	}
	return 0;
}

// Define all your functions here

int readFile(char* inputFileName, int* wordCount, char array[][MAX_WORD_LENGTH], int flag)
{
	FILE *fp;
	fp = fopen(inputFileName, "r");

	if(fp == NULL)
	{
		printf("\n Unable to open the file. Aborting");
		exit(EXIT_FAILURE);

	}

	while(fscanf(fp, "%s", array[(*wordCount)++]) > 0);

		return 0;
}

int writeToFile(char* outFileName, int wordCount, char array[][MAX_WORD_LENGTH])
{
	int i = 0;
	FILE *fp;
	fp = fopen(outFileName, "w");

	if(fp == NULL)
	{
		printf("\n Unable to open the file. Aborting");
		exit(EXIT_FAILURE);
	}
	
	for(i = 0; i< wordCount; i++)
	{
		fprintf(fp, "%s\n", array[i++]);
	}

	return 0;
}

void usage(char* processName)
{
  printf("Usage %s [-s] [-t] inputFileName outputFileName\n", processName);
}
