Hi im new to C programming and im having trouble with one of my projects..I dont know how to start it off.
Basically this is what i gotta do:

Write a C program that emulates a simple LED panel display. The program must implement the required features below:
Accept one input integer from standard input.
Print text to standard output which resemble a LED panel display of the input value (see examples below).
Correctly process input values from zero to 9999.
Print an error message to standard output when the input value is not supported by the program.

The suggested size of each LED digit is 3x5, but, students may choose a larger size.

The program must include source code comments to explain the design of the program.

any help will be greatly appreciated
