The variable i is both referenced and modified in the same
expression.

Answer / abdur rab
The answer from wikipedia
Sequence point comes into play when the same variable is
modified more than once. An often-cited example is the
expression i=i++, which both assigns i to itself and
increments i; what is the final value of i? Language
definitions might specify one of the possible behaviors or
simply say the behavior is undefined. In C and C++,
evaluating such an expression yields undefined behavior.

A banker has a seif with a cipher. Not to forget the cipher, he wants to write it coded as following: each digit to be replaced with the difference of 9 with the current digit. The banker chose a cipher. Decipher it knowing the cipher starts with a digit different than 9. I need to write a program that takes the cipher from the keyboard and prints the new cipher. I thought of the following: Take the input from the keyboard and put it into a string or an array. Go through the object with a for and for each digit other than the first, substract it from 9 and add it to another variable. Print the new variable. Theoretically I thought of it but I don't know much C. Could you give me any kind of hint, whether I am on the right track or not?
