Problem Statement

Split a (character) string into comma (plus a blank) delimited strings based on a change of character   (left to right). Show the output here   (use the 1st example below).

Blanks should be treated as any other character   (except they are problematic to display clearly).   The same applies to commas.

For instance, the string: should be split and show:

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Split a character string based on change of character step by step in the Cowgol programming language

Source code in the cowgol programming language

include "cowgol.coh";

sub split(in: [uint8], buf: [uint8]): (out: [uint8]) is
    out := buf;
    loop
        [buf] := [in];
        if [in] == 0 then break; end if;
        if [in] != [@next in] and [@next in] != 0 then
            [buf+1] := ',';
            [buf+2] := ' ';
            buf := buf+2;
        end if;
        buf := buf+1;
        in := in+1;
    end loop;
end sub;

var buf: uint8[32];

print(split("gHHH5YY++//\\", &buf[0]));
print_nl();
