Learn and Master C Programming - Bit-wise Left Shifting Operator (<

The video tutorial explains the concept of bit shifting, specifically left shifting, as a method of multiplying a number by two. It uses an example of shifting the number 4 left by two bits, demonstrating the process of inserting zeros and moving bits to the left. The tutorial also discusses the importance of bit size, using a 32-bit number to show how bits are shifted without falling off. The result of shifting 4 left by two bits is 16, equivalent to multiplying 4 by 2 twice.
