// resistor.2.3c - 1/24/23 - C. Bradley - With help from God

/*
 This program calculates Ohm values for electronic resistor components
 using input values for each of the four (4) bands of color.  A diagram will
 help the user to enter the appropriate number depending on what color(s)
 the user sees in each of the 4 bands.  The graphic will also explain the
 the different "functions" of each of the 4 bands. The final Ohm value
 will also display a + or - tolerance range for the mean Ohm value (in Ohms).

 Note: This version of the program has been updated to display color
 for TEXT for all four resistor bands.

// 1/23/23 - Editor's Comment Area:

// C does not permit function declarations *inside* function declarations.
// So yellow() and reset() were moved *outside* main.

// Also, we need to put the *same number of variables* at the tail end of the printf
// statements as there are %s format specs in the "blah blah blahs"

// Added orange etc.
