I figured it out, I mis-understood how the provided code for the tree works. It seems that the "root" node is not actually the root and I have to pass the tree->root->left node. I assumed this was...

I'm using the same tree that was printed with the supplied code.

I also narrowed down where the issue is using print statements. I go to my function to print the nodes

I got it to work using fprintf(). The problem was that there were newline characters inbetween some of the values

I agree, struct that contains first name, last name, and grade would be a better idea.

I have the struct to read in the header info from the original file and to store it. I will read up about padding and alignment to see if that helps. Thanks.

I am having trouble writing the PGM header info to a new pgm file. When i do a hex dump of the first 20 bytes of the original and new header, i can see that "P5" is correct in both the original and...

Thanks for you help. It works if i put in another fscanf to check for any extra characters on the line.

Thanks. So since its trying to read the rest of the line, how do i tell it to disregard that and start at the next line?

i thought that when i use the [^\n] in the fscanf statement, that reads until the newline even if the characters are not put in the array.

Im still a little confused. It reads in the line of text, the first 79 characters. How do I get it to read in the next line the next time around the loop.

Here is the text im trying to read in:

I created a function that reads in an int and a line of text. I read it into an array of size 80 so i only read in 79 characters. That part works, it will read in only 79 characters of a line of text...
