Thread: Will 'static' optimise my code?

Code:

void samRing::getParameterDisplay (long index, char *text)
{
	static char waveName [4] [4] = { "Sin", "Tri", "Squ", "Saw" };

	switch (index)
	{
		case pFreq:
			sprintf (text, "%d", (int) (freq * MAX_FREQ));
		break;

		case pWaveType:
			strcpy (text, waveName [waveType]);
		break;

		case pDry:
			sprintf (text, "%d", (int) (dry * 100));
		break;
	}
}

I'm presuming that because the array is static, the assignments will only occur once. In all subsequent calls, this will be skipped over. Am I right?

Yes, after waveName is initialized the first time the function is called, subsequent calls won't reassign it. But any speed gain will probably be negligible.

I wasn't hoping to make great gains in speed, I just didn't like the thought of that array being re-assigned every call - it's just sloppy. But thanks for the const idea, I'll do it.
