Shifting bits

“

- [Instructor] The C language's Bitwise Operators work by shifting the bits in a byte, which is a very low level programming concept. It has some interesting uses. The operators work like math expressions. X is an integer variable to shift right or left by N bits. The result is saved in integer variable A. Zero bits are shifted into the value from the left or right, depending on the operation. Bits shifted off the edge are gone into the ether. In the C++ Programming Language, these operators take on different roles. This is one area where C and C++ differ. This code demonstrates how a bit shift looks at the binary level. I use my bin string function to output a string representing bits in a byte. In the main function, you see the shift take place at line 29. The value of variable A is shifted left one bit position, and the loop repeats 16 times. Pretty. Now I'm going to modify the code so that the shift is two positions. The shift happens a lot faster. At the binary level, shifting…
