C语言中易错的优先级

#include <stdio.h>#define STRUCT(type) typedef struct _tag_##type type;\struct _tag_##typeSTRUCT(Demo){int* pInt;float f;};int func(int v, int m){    return (v & m != 0); //((v & m) != 0);}int main(){    Demo* pD = (Demo*)malloc(sizeof(Demo));    int *p[5];// int* p[5];    int *f(); // int* f();    int i = 0;    i = 1, 2; //i = (1, 2);    *pD.f = 0;//pD->f 或者 (*pD).f    free(pD);    return 0;}
