    Thanks a lot, that helps a lot. I'm on my last stat, I have to find the most commonly occuring word(s). Heres my function-

    Code:
    void commonWord(double count[], int array_length, words array[])
    {
    	int commonCount[Num];
    	int max;
    	max = count[0];
    	int j = 0;
    	int i = 0;
    	int k = 0;
    	
    	for(i = 1; i<array_length; i++)
    	{
    		if(count[i] > max)
    			max = count[i];
    		else if( count[i] == max)
    			{
    				commonCount[j] = i;
    				j++;
    			}	
    	}
    	
    	cout<< "The most commonly occuring words are: "<< endl;
    	
    	for( k = 0; k<array_length; k++)
    		cout<< array[commonCount[k]].word<< endl;
    }
    I dont get a compile-time error. But when I run the program, I get a message telling me the .exe file stopped working.

    I'm now trying to write my stats to a text file, but its only writing two of the stats, and those stats come from the same function.

    Heres the code -


    Code:
    #include <iostream>
    #include <fstream>
    #include <cstdlib>
    #include <string>
    #include <iomanip>
    using namespace std;
    
    int const wordLength = 21;
    int const Num = 100;
    int const fileSize = 255;
    
    struct words
    {
    	char word[wordLength];
    	int count;	
    };
    
    
    	
    void storeFile(char[], char [], words []);
    void displayFile(char[], char[], words[]);
    int wordSearch(char word[], int array_size, words []);

    int sort (words [], int, int);

    The "storeFile" function is the only one that prints to the file.
    BTW I know this code is unorganized and not the best way to do it, but this project is due tomorrow (12-10) so I'm just trying to turn in what I have.

    They each write out to the file just fine. But of course, since each function starts by erasing the file before writing to it....

    Thanks for the quick reply. I started messing with "outFile.put(out_file_name);" but that didnt work. Out professor told us only to read the first two chapters on "I/O File Streams and Data Files". However it wasn't intill the 5th chapter where it starts explaining file stream as function arguments. So I wonder why he didnt make that chapter assign reading. Well anyways this thread is solved.
