Addieren und Vergleich

[Swordfish]

Warum sagst du es nicht gleich so?

#include <math.h>
#include <float.h>
#include <string.h>

float average( const char *string ) {

	unsigned    sum    = 0;
	size_t      count  = 0;

	while( *string ) {

		sum += *string - '0';
		++count;
		++string;
	}

	return count ? sum / ( (float) count ) : 0.0f;
}

int besser( const char *a, const char *b ) {

	float average_a = average( a );
	float average_b = average( b );

	if( fabsf( average_a - average_b ) < FLT_EPSILON ) {

		return 0;
	}

	return average_a < average_b ? -1 : 1;
}
