题目：#if #ifdef和#ifndef的综合应用。 1. 程序分析： 2.程序源代码： 复制代码 代码如下: #include stdio.h #include conio.h #define MAX #define MAXIMUM(x,y) (x>y)?x:y #define MINIMUM(x,y) (x>y)?y:x void main() { int a=10,b=20 #ifdef MAX printf( \40: The larger one is d\n ,MAXIMUM(a,b)) #else printf( \40: The lower one is d\n ,MINIMUM(a,b)) #endif #ifndef MIN printf( \40: The lower one is d\n ,MINIMUM(a,b)) #else printf( \40: The larger one is d\n ,MAXIMUM(a,b)) #endif #undef MAX #ifdef MAX printf( \40: The larger one is d\n ,MAXIMUM(a,b)) #else printf( \40: The lower one is d\n ,MINIMUM(a,b)) #endif #define MIN #ifndef MIN printf( \40: The lower one is d\n ,MINIMUM(a,b)) #else printf( \40: The larger one is d\n ,MAXIMUM(a,b)) #endif getch() }
