Question Question about Arrays
Ok this is probably pretty easy but I'm stuck.

My program reads the contents of a txt file and stores the string into a char array called buff. The contents of the text file is a string of a txt file name. So basically buff has this value "file.txt\0". The last part is the null character. I want to use buff in an open system call like so: open( buff, O_RDWR ), and the file, "file.txt" will open. But you can obviously see the problem, open() is trying to open "file.txt\0" instead. How can I modify buff so that it isn't looking for the filename with an appended null char on the end? Thanks for reading this.
