print_hex

Your mission

Write a program that converts a non-negative decimal integer to its lowercase hexadecimal representation.

See it in action

./print_hex 31

Expected result

1f

Your checklist

For your own tracking. Tests grade your code.

The program expects exactly one argument: a non-negative decimal integer that fits in an unsigned int.
Convert the value to base 16 using lowercase letters (a-f).
Print the hexadecimal representation followed by a newline (\n).
If the program does not receive exactly one argument (argc must be 2), print wrong number of arguments followed by a newline.
You may only use the write function.
