Aug 12, 2014 at 5:38	comment	added	Azurespot		Hey I fixed it!!! Turns out my error was in some `argv[1]` code I had. I tried to use `isalpha(argv[i])` to make sure the key entered is only letters, but that would not check for the whole string (which is what our key is in this exercise), it would only check for one character in the key. So I had to create a for loop to iterate through `argv[]`, using `strlen(argv[1])` as my middle loop condition, so it would check each character separately.

Aug 12, 2014 at 4:34	comment	added	Azurespot		Thanks sinister! I was not aware I could not have 2 expressions separated by a comma. I saw that you can have that in the 1st and last condition, e.g. `int i = 0, j = 0;` and here too `i++, j++`, so I assumed it was okay to have it in the middle. But thanks, I changed it an && and that fixed it. Now I'm having a new problem though, a `Segmentation fault (core dumped)`, so I will have to figure out that one. :/
