Bitwise AND uses the “&” symbol. It checks if the two inputs are numbers and if so then it gives back a 1.

For example if we have an int set to 12 and an int set to 6 if we preform a bitwise & operation on them the result would be a 0100. 12 in binary is 1100 and 6 in binary is 0110.

In this example of bitwise & gives us the result as 4. You can test this out yourself in code.

    int num1 = 12;    // Binary: 1100
    int num2 = 6;     // Binary: 0110
    int result = num1 & num2;  // Perform bitwise AND operation
 
    printf("num1: %d\n", num1);
    printf("num2: %d\n", num2);
    printf("result: %d\n", result);

it prints out the result as follows:

num1: 12
num2: 6
result: 4

Bitwise OR uses the “|” symbol. It checks if the either of the two inputs are not zero and gives a 1.

In this example the result of 12 or 6 is 14.

Bitwise XOR uses the “^” symbol. Returns 1 only if the 2 bits are different.

Bitwise NOT uses the “~” symbol. It inverts all the bits in a single number.

To make a larger paddle, all you'd have to so is extend your paddle collision to double the length of your paddle and draw a second paddle where the first one ends, or alternatively use a different paddle sprite

You can use the same select region to draw both paddles, like so

  select_region( Paddle );
  draw_region_at( PaddleX, PaddleY)
  draw_region_at( PaddleX + [paddle length], PaddleY)

Where [paddle length] is the length of the paddle

To code in multiple hit points for bricks, your brick struct should include an integer member for HP and visibility.

Within your calculations for ball-brick collision, make a check to see if the current brick is visible (if not, do not process collision detection). If collision is detected, decrement the brick's HP. If HP is 0 after it is decremented, then toggle the brick's visibility.
