    Suppose i have a file in which i have strings and integers

    I want read that file and wants to store in an array.

    My problem is how to differciate whether the read one is string or integer.

    Because i need to manupulate the data .

    if the file you are reading only contains strings and numbers then u can easily do it...(i.e. there are no alphanumeric words in the file)

    in this case
    1) read every word from the file as a string ...
    2) convert the string into a number using atof
    3) if the input is a string the return value of the function atof is 0 otherwise the return value will be
    the number converted.
    4) put a check in your program for the return value of the function and you are done
