int myVar = 1; myVar = myVar << 1;

This code performs a bitwise left shift operation on the integer myVar. Here's what it does step by step:

  1. Declaration and Initialization:

    int myVar = 1;
    

    This declares an integer variable myVar and initializes it with the value 1.

  2. Bitwise Left Shift Operation:

    myVar = myVar << 1;
    

    The << operator shifts the bits of the number to the left by the specified number of positions. In this case, it shifts the bits of myVar by 1 position to the left.

    • In binary, the value 1 is represented as 0000 0001 (assuming an 8-bit system for simplicity).
    • When you perform the left shift by 1, the bits shift left, and a 0 is added to the right:
      0000 0001 << 1 = 0000 0010
      
    • The result is now 2 in decimal.
  3. Assignment: The result of the myVar << 1 operation is assigned back to myVar.

Final Result:

After the execution of this code, the value of myVar will be 2.

In summary, the code initializes myVar to 1 and then shifts its bits to the left by 1 position, doubling its value. As a result, myVar becomes 2.
