• 求两个数的乘积和商数，该作用由宏定义来实现

  解：#include main()#define product(a,b) (a*b)#define divide(a,b) (a/b){float result,n1,n2;printf(“input n1:”);scanf(“%f”,&n1);printf(“input... [宏定义]

• 计算 s=(x*y)1/2，用两个宏定义来实现

  解：#include #include main()#define s1(a,b) ((a) *(b))#define s(c) sqrt(c ){ float result; int n1,n2; scanf(“%d”,%n1); scanf(“%d”,&n2);... [宏定义]
