#include <stdio.h> #include <malloc.h> int reset(char**p, int size, int new_size) { int ret = 1; int i = 0; int len = 0; char* pt = NULL; char* tmp = NULL; char* pp = *p; if( (p != NULL) &...

#define Mul(x , y) ++x*y ++ int main() { int a = 2; int b = 4; int c = 8; printf("%d",Mul(a+b,b+c)); return 0; } 结果：++a+b*b+c++=3+16+8=27 27

#include<stdio.h> #define MAX 100 int main() { int i = 0, sum = 0; do{ if(i!=(i/9)*10) sum += i; }while(++i<MAX); printf("%d",sum); } 结果是：4590
