I need to write pseudocode to, in part, read a value and validate if it is indeed two alphas followed by four numerics, ie AA1234. How would that line of pseudocode look? Thanks so much.

@ross82573,

I don't know... Does it have some relation to reality??? It cannot be code if it is wrong or random...

@ross82573,

Maybe something like this . . .

Code:

set index to string length

set result to TRUE

for index >= 0

    if index > 1

        if not numeric char

            set result to FALSE

            exit for loop

        end if

    else

        if not alpha char

            set result to FALSE

            exit for loop

        end if

    end if

end for

@George,

Thanks George -- it just seems so involved, you know? as in too many lines of pseudocode.......ugh I hate this.

The question says:

"design a program that will read the parts of an inventory file, validate the part number on each record, etc etc."

The instructor gave us a nugget that said "the part number is 6 characters. two letters followed by 4 numbers. AA1234 for example. Check that the first 2 are alphas and the last 4 are numbers"

I remember back in high school when I wrote BASIC that you were able to count back characters and check if those (like the 4th unit or whatever) was a number or letter or whatnot. That's what I am looking for in this......you know?

In the pseudocode the "4th unit or whatever" is the index into the
string (the part number). Indexing is from zero where zero is the first
character in the part number. Index zero and one must be characters,
the rest mus be numerals. You would write this as a subroutine called
with a pointer to the part number as input and the result as the output.
It assumes that there are utilities which can determine the length of the
string and whether a character is alpha or numeric.
