    Question reading file and storing to arrays

    Hi,

    I am trying to read a file and store its content into 2 seperate arrays (one char** the other a int array) - the content of the int array is modified and then rewritten to the file (overwritting file).

    sample text file:

    aaaa 304
    bbbb 120
    ccccc 441
    dddd 5
    eeee 61

    Code:
    #include <stdio.h>
    
    void main()
    {
    	FILE *pFile;
    	int x=0;
    	int num[5][100];
    	char arr[5][100];
    	int buff[100];
    
    	pFile = fopen ("log.txt", "r");
    
    	for (x=0; x<5; x++)
    	{
    		fscanf (pFile, arr[x]);
    		fscanf (pFile, num[x]);
    	}
    	for (x=0; x<5; x++)
    	{
    		printf ("Arr: %s", arr[x]);
    		printf ("Num: %d\n", num[x]);
    	}
    }
    It seems that i am reading garbage into arrays...

    Still using void main huh?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    And that's supposed to make it OK?
