macOS c++ Mac OS X stray \20 error

[paulmcco]

Hello, I get this error from code within a header file...any ideas?

ScorePlayerMatch.h:25: error: stray '\20' in program
ScorePlayerMatch.h:25: error: parse error before numeric constant

#include <Carbon/Carbon.h>
struct scoreMatch {
	double scoreArr[5][2];
}ScorePlayerMatch();

scoreMatch ScorePlayerMatch(double pair, double threeKind, double twoPair, double fourKind, double fullHouse, double pairCard, double secPairCard, double threeKindCard, double highC, double lowC)
{
	scoreMatch infunc;
	infunc.scoreArr[0][0] = pair; 
	infunc.scoreArr[0][1] = 2.0*pow(10.0,6.0) + (pairCard * 10000.0) + (highC) + (lowC/100.0);
	infunc.scoreArr[1][0] = threeKind; 
	infunc.scoreArr[1][1] = 4.0*pow(10.0,6.0) + (pairCard * 10000.0) + (highC) + (lowC/100.0);
	infunc.scoreArr[2][0] = twoPair; 
	infunc.scoreArr[2][1] = 3.0*pow(10.0,6.0) + (pairCard* 10000.0) + (secPairCard*100.0) + (highC) + (lowC/100.0);
	infunc.scoreArr[3][0] = fourKind; 
	infunc.scoreArr[3][1] = (8.0*pow(10.0,6.0)) + (pairCard * (1.0 * pow(10.0,4.0))) + (highC) + (lowC/100.0);
	infunc.scoreArr[4][0] = fullHouse; 
	infunc.scoreArr[4][1] = 7.0*pow(10.0,6.0) + (pairCard*10000.0) + (threeKindCard*100.0) + (highC) + (lowC/100.0);
		
	return infunc;
}

One idea: don't write functions in header files.

Another:
od -ta thefile.h
Look through the output for the rogue character, then remove it.

Well, the compiler tells you.
There's a character in your file that doesn't belong there.
It's not a printable character, that's why the compiler shows it in octal. ("\20").
Find out who to see characters in your source file that are normally invisibile.
Then delete anything that doesn't belong there.

The snippet you posted is less than 25 lines, so it's perhaps somewhere else.

One often-occurring cause for having weird characters in your source files is copying it off a web site. Did you type in this code yourself, directly in Xcode?

Also, \20 is ASCII 16, which is a rare control character ("Data Link Escape"). Maybe you ended up feeding UTF8 code to the compiler or something?
