 EFFICIENCY
************/

//- clean up any inefficiencies in program (unecessarily large arrays, redundant strings, e.t.c)
//- search for blocks of common code
//  below code:
	min(num1, num2)
	int num1, num2
	{
		return ((num1<num2)?num1:num2);
	}
//  and the macro defination
	#define min(num1, num2) ((num1<num2)?num1:num2)
//  do the same thing.  However the macro does the task in less space and uses less processing time
