The first thing might be to fix all the compilation errors.
It might look like C, but you need a C++ compiler to compile it.


$ gcc -g bar.c
bar.c: In function ‘successor’:
bar.c:235:5: error:...

Have you actually read any books or courses on compiler construction?

Just making it generate correct code will be achievement...

First off, trying to time anything calling printf is a fools errand.
You're trying to measure an ant-fart in a hurricane.

Second, it's basically the same code whichever way you write it.

Well if you don't mess up the numbering with an assignment, you typically do this.


typedef enum {EMPTY, RST, PWM_DIV, PWM_DUTYCYCLE, DAC_REF, ADC_SAMP_TIME, ADC_NUM_SAMPLES, ADC_CONV, CMD_LAST}...

> char sorted_key[strlen(key)];
This should be
char sorted_key[strlen(key)+1];

You need the +1 for the \0 at the end of the string.

Compile with the -c flag, then use the nm tool to find out what the external names actually look like.


$ g++ -c foo.cpp
$ nm -u foo.o
U __cxa_atexit
U...

Consider some refactoring of the code.

Then this.

Garbage at the start of the string is a sign that you're not initialising your dynamically allocated string properly.

See my example.

Well if you have all the characters in a buffer, like

char buff[] = "24A3\r";

Then strtol, strtoll - cppreference.com
long x = strtol(&buff[1], NULL, 16);

It would be helpful to see an example of a before and after.

Well read_string isn't actually storing anything in sentence.

Well saying _TEXT and L together is redundant.
The _TEXT macro automatically puts an L in the result when in UNICODE mode.

Eg
_TEXT("HelloMsg")

I also had to save the source file as a UNICODE...

Recall that a string constant has a type of 'const char *'

And all string constants will compare as not equal to NULL.
A pointer in a boolean context is implied as comparing it with NULL.
So in...

I'd say it rather more depends on which OS you're targetting.

What research have you done?
block writing to usb at DuckDuckGo

Where you would use
for ( row
for ( col

to print "HelloI"

You would use
for ( col
for ( row

So is it working then?

If you want it to keep going, you shouldn't be doing this.
finished = paComplete;

What?

Oh wait, you wrote this on your phone rather than copy/pasting it from your text editor.

Come back when you're...

Put a breakpoint here, then use the debugger to disassemble code to see if it's what you expected.

Then maybe even single step it.
