    PLZ help in using fread,fwrite ..

    Hello,This is my first pardon me if make any mistakes

    can any 1 tell me how to use fread from stdin(FROM CONSOLE)

    for example: i want to take 100 numbers as input ..and also perform some operations on them..
    how do i do that ? because fread takes BINARY INPUT...can any 1 plz help me in this aspect ?

    PS: The reason i am using fread instead of scanf is because i heard that fread is much faster than i want to extend this to very large input/

    Take a look at the Enormous Input Test thread, especially towards the end. The code is C++ but most of the suggestions are also C.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    I think you'll find that typing in 1000 and reading with fscanf is considerably easier than
    typing in alt-000 alt-000 alt-003 alt-232 and using fread.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
