这个程序看不懂 能为我详细解释一下吗？ 求大神
# define LOW 10
# define HIGH 5
# define CHANGE 2
int i = LOW ;
#include <stdio.h>
void main( )
{ int workover ( int i ) , reset ( int i );
int i = HIGH ;
reset ( i / 2) ;
printf(" i = %d \n ", i );
reset ( i = i / 2) ;
printf(" i = %d \n ", i );
reset ( i / 2) ;
printf(" i = %d \n ", i );
workover ( i );
printf(" i = %d \n ", i );
}
int workover ( int i )
{ i = ( i % i ) * (( i * i ) / ( 2 * i ) + 4) ;
printf(" i = %d \n ", i );
return ( i );
}
int reset ( int i )
{ i = i <= CHANGE ? HIGH : LOW ;
return ( i );
}
