int (*p)(int,int);//declare a function pointer p=max;//the function point must has the same return type and parameter type with specified function. printf("max(2,3) is %d",p(2,3)); } //the result is 3; also , we can use typedef to define a function pointer type to simplify...
When declaring pointer data or a function that returns a pointer type, the preferred use of*is adjacent to the data name or function name and not adjacent to the type name. Examples: char*linux_banner;unsignedlonglongmemparse(char*ptr,char**retptr);char*match_strdup(substring_t*s); ...

The current compiler correctly gives an error, because the template parameter type doesn't match the template argument (the parameter is a pointer to a const member, but the function f is non-const): Output Copy error C2893: Failed to specialize function template 'void S2::f(void)'note:...
