Your 1st half of the array array[x][0] is never initialized to zero so the values start out with garbage.

Load 19 random values. If a 0 is generated during these 19 values, remember that fact.

For the 20th value, if a 0 was not generated, load a 0, otherwise get one more random number.

Consider this loop:

for (i = 0; i < 5000; i++)
{
sprintf(ifile, "file%04d.dat", i);
sprintf(ofile, "output%04d.dat", i);
//process the files
}

1: Zero your Total
2: Read the input as a string (hex)
3: Check each character and conve rt it into decimal value (A=10, B=11, etc)
4: Multiply Total by 16 and add the above value
5: Back to 2

What you are attempting to do can be done with arrays.


With audio as an array, you can reference audio[1], audio[2], etc.

No. It would be fscanf(infile, "%s", arr[i]);

But, see this about scanf/fscanf (http://www.gidnetwork.com/b-62.html). It would be better to use fgets() instead.

No, you don't want this. At least not in total.
First, %c reads a single character
Second, %s reads a string, but you don't want to use it. Here's why (http://www.gidnetwork.com/b-62.html)...

What he's getting at is variables should be defined only in code files, the .C or .CPP files. NEVER put a definition in a header file. Only the extern goes in the .H file.

You need to test the value after reading it. If invalid, start the loop.

Although the continue works in this situation, there are many times it won't work, so Aia's solution is better.
