What is the purpose of void pointer?
Write a program to replace n bits from the position p of the bit representation of an inputted character x with the one's complement. Method invertBit takes 3 parameters x as input character, p as position and n as the number of positions from p. Replace n bits from pth position in 8 bit character x. Then return the characters by inverting the bits.

Why do we use null pointer?
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?
