    Fgets + sscanf

    I am reading input from a file using fgets, and then using sscanf to put what was read into a variable.

    The problem is now I have an area which can contain upto 2000 chars.

    The problem is how can use fgets in combination with sscanf within a loop.

    I can stop reading when two consecutive periods are found.

    Any input would be appreciated.

    Thanks

    So have a 2001 byte read buffer.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    But every time sscanf reads it will only read one word. My problem is knowing how to use sscanf when Im not sure how many words it will read.

    sscanf won't test for consecutive characters (assuming you were thinking of using the %[...] specifier). You'll have to do it manually with strstr and friends, or assume that a single period will just not happen.
    My best code is written with the delete key.
