Silly things of why C doesn't have that?

Code:


uchar* int myFunction()
{
    return myCharPointer, anInt;
}

I know, make it a struct, use tuples or other.
Assembly function would return things in multiple registers. C only 1. Why not upgrade C++ 23?

Second

Code:


for (int y = 0; y < 10; ++y) {
	for (int x = 0; x < 10; ++x) {
		if (x > 5 && y > 5) break 2;
	}
}

You want to break twice.
Use a goto and see people screeching.
Yeah, put a boolean that you set and check/escape twice. Or rewrite.
Make this loop into a lambda that escapes it self but not the whole function outside.

Finally

Code:


int a = 10;
int b = 0xABCD;
int c = 01234; // octal?
int c = 0b101010101010; // doesn't exist

THE low level language and no binary? We have to use defines with hex or bit shifting. When I change flags in hardware and want to put one by one the bits. Someone said make a function that accepts a string and returns back tha value.

But it has octal. Why no binary? Even basic had binary.

They make fun of Basic, but modern scripting languages are like a basic.

python and basic do not have much in common except the interpreter ;)

never done X86 assembly before, still not quite used to it

@DevEd, in that specific sequence, you could do "LODSW" to save a byte.
It does do "mov ax,[si]" + "inc si" + "inc si" ... override with CS is fine =)

Haha, that's a good one. :) However, why do you need to mix OS and hardware code? It usually is not really a good idea.

Synthesizing some guitar-ish sounds (original idea by GM, with a "twist"):

Code:

float r1 = (lfsr_randf(&voice->lfsr_1, 2.0f/*max*/) - 1.0f) * voice->mod_seed1scl_cur;
float r2 = (lfsr_randf(&voice->lfsr_2, 2.0f/*max*/) - 1.0f) * voice->mod_seed2scl_cur;
float r3 = (lfsr_randf(&voice->lfsr_3, 2.0f/*max*/) - 1.0f) * voice->mod_seed3scl_cur;
float r1mr2 = (r1 - r2) * voice->mod_scl1_cur;
float r2mr3 = (r2 - r3) * voice->mod_scl2_cur;
out = r2mr3 - r1mr2;

// now add a HPF to get rid of the DC offset, an env-modulated LPF+DCA, ..and find good params
sound example
(note: I also made a version for my "Cycle" sample precalculator that runs on an A500, w/o floats, of course)
