show_bits

Your mission

Implement a function that receives an unsigned byte and outputs its eight-bit binary representation, MSB first, with no trailing newline.

See it in action

show_bits(1)

Expected result

00000001

Your checklist

For your own tracking. Tests grade your code.

The function receives a single unsigned char parameter.
Always output exactly 8 characters, each character is either 0 or 1.
Start with the most significant bit (bit 7) and end with the least significant bit (bit 0).
Use write to output each character; do not call printf or putchar.
Do not write a newline after the bits.
