title: Changing a Bit in C Programing
body: <p>I am coding in C programming. 
  Let's say I have a character: 
  char letter=0x0000;
  So the binary data for the letter is now "00000000"
  let say I want change the binary data to "10000000" and later to change it "10010000", is there a bitwise operator or method that would allow me to change a "0" to a "1" or "1" to a "0" at a specific position. Also is this possible?</p>
