C语言指针

[codingWang]

• 函数指针

  
  int fun_name(char* param1,char* param2){
   //todo
   return 0;
  }

void main(){ //声明函数指针：返回值类型+函数指针的名字+参数列表 int (fun_virable_name)(char param1,char* param2) = fun_name; fun_virable_name("111","222"); }

- 函数指针传参

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

void param_with_point(int(* add_fun)(int a,int b),int m ,int n ){ int result = add_fun(m,n); }

void main(){ param_with_point(add,10,20); }
