bit1,bit3,bit4 are called bitfields. We may not want to use entire 4 bytes of an integer to store a small number. These variables allow u to define thw width to make use of only the necessary bytes and share the remaining space.
bit1 is allocated 1 bits
bit3 4 bits
bit4 4 bits
So total 9 bits
The first int variable is allocated only 1 bit of 32-bits. the remaining space is allocated for other two variables. Hence all the variables share the same space of the int, whose size is 4 bytes
