typedef

 

结构体

typedef struct{
    char *Sname;
    int age;
}structName;

枚举

typedef enum{
   oneEnum=1,
   twoEnum,
}enumName;

函数指针宏定义

    typedef int (*p)(int ,int);
//    int (*p)(int ,int)=sum;
    p s=sum;
    int end = s(12,12);
    printf("end=%d",end);

 int sum(int a,int b){
    return a+b;
}

指向函数的指针

struct person
{
    int age;
};
typedef struct person * per;

typedef struct{
    int age;
}*personPoint;

   struct person ps={23};
    per ppp=&ps;
    personPoint perp=&ps;
