C programming question.

hi ....

The user gives me a number between 1 and 70000, I need to print this value out onto the console using two bytes of char type, even if the number is less than 255 I need the first byte to be 0, example: number = 7, my output is 00 07. The instructor suggested printing a single character, which works for numbers <255, but how do I print a number >255 as 2 characters? The professor said to use char type and bitwise operations. thank you.
