    reading input without knowing datatype

    i am supposed to read an input line (no termination condition is given hence i assume it to be '\n')
    Now the input contains of
    operands - int
    operators - char

    and i am to calculate the expression
    eg : 2 + 4

    note : i have used gets to read the whole line and store it in a char[] variable
    then in a loop i read each char from it using sscanf to process it
    but the problem is the terminating condition (the loop goes infinite if i use '\n' or '\0' )
    i have also tried concat of the string in char[] with a specific char like # and then check for it but it does not work !

    how do i do this ?

    You should read this FAQ entry on why you should never use gets.

    While you're at it, you should read the Announcements for suggestions on how to use this forum properly. (IE: Post some code. Use code tags when you do it.
