#define P 3 #define S(a) P*a*a main() {int ar; ar=s(3+5) printf("\n%d",ar) } 这个答案是29,不懂.
#define P 3 #define S(a) P*a*a main() {int ar; ar=s(3+5) printf("\n%d",ar) } 这个答案是29,不懂.
#define P 3 #define S(a) P*a*a main() {int ar; ar=s(3+5) printf("\n%d",ar) } 这个答案是29,不懂.
#define宏都是直接替换的,不会计算后再替换.
s(3+5) = p*3+5*3+5 = 9+15+5 =29
若想计算后在替换,需要加上括号:
#define S(a) P*(a)*(a)
#define
#define s(x) 3
#define S(x) 3
define是什么意思
下列程序运行结果为:#define P 3 #define S(a) P*a*a main() {int ar; ar=S(3+5); printf(
%d,ar); }
#define P 3 #define S(a) P*a*a main() {int ar; ar=s(3+5) printf(
%d,ar) } 这个答案是29,不懂.
#define 后面的意思// macros for accessing triangle corners#define TIN_TRIANGLE(i) (i/3)#define TIN_CORNER(i) (i%3)#define TIN_INDEX(t,c) (t*3+c)#define TIN_NEXT(c) ((c+1)%3)#define TIN_PREV(c) ((c+2)%3)
