Unknown Error - Solution?

#include <stdio.h>
float calculateCharges(float hours);

main( )

{	int i=0;

	printf("Enter in the number of cars");
	scanf("%d", &i);

	const int  NUMBER_OF_CARS=i;

}

float calculateCharges (float hours)

	if(hours>3 && hours<16)
		{return 2.00+(hours-3)*0.50;}

I keep receiving the error

The compiler found a problem before line 43 in stdarg.h.

This is a standard C header that is included in stdio.h. These standard headers are compiler-specific and I don't have the one for your compiler. You might look there and post the code a little before and including line 43.
