Third, the function pointer declaration. What replaces Your question isn't clear, but I think you might want something like this:You are right. However, typedef construct only makes the writing/reading of a program easy; the compiler just expands the typedef definition before compiling … Fourth, use a pointer to call a function. Fifth, use typedef to simplify. The function pointer can be conveniently used to point to the different functions of the same return type and taking same number of arguments. the following: int …

Detailed refer to the C ++ pointer: C ++ pointer to explain in detail.
You must first do the typedef (a function pointer, I presume) and than use that typedef to define a variable (of type pointer to function) initialise the pointer with the function you want, and than use that variable to invoke the function that it ponts to. It gives a new name to a type that may make program more readable. (*) This is relevant as soon as you have multiple declarations in a single line, e.g. – wildplasser Jun 14 '12 at 17:43. add a comment. Stack Overflow for Teams is a private, secure spot for you and

Now we can use a typedef to create a named function pointer type called printer: typedef void (*printer_t)(int); This creates a type, named printer_t for a pointer to a function that takes a single int argument and returns nothing, which matches the signature of the functions we have above. To use it we create a variable of the created type and assign it a pointer to one of the functions in question: I thought my boss had told me to use a typedef to make this work.
