    Problem while dealing with file handling functions

    i wrote a program to copy multiple text files into a single text file. For 13 text files it works fine. But when the number is greater than 13 i.e. iether 14 or more than that the program is not able to open files.( from the 14th file). Do anybody have any idea what is goin on. Is there are some restrictions while opening a massive number of files from a c program.?

    Welcome to the forums!

    There is a limit on the number of files that can open at the same time. This limit is specified by the constant FOPEN_MAX. The C standard guarantees that it will be at least 8, including stdin, stdout and stderr. However, most modern compilers, support a significantly larger number.

    You should attempt to redesign your algorithm to only have a minimum of files open at the same time. From your description of the task, you should only need two files open (one to read from and one to write to).
