Using Vs Typedef Decoding Common Word Mix Ups

Using Vs Typedef Decoding Common Word Mix Ups 16. both keywords are equivalent, but there are a few caveats. one is that declaring a function pointer with using t = int (*)(int, int); is clearer than with typedef int (*t)(int, int);. second is that template alias form is not possible with typedef. third is that exposing c api would require typedef in public headers. Using just brings declaration into the local scope, while typedef introduces a typedef name. one difference between them is elaborated type specifiers, e.g.: class foo. }; class foo f1; ok, declares f1 variable of type n::foo. class n foo f2; error, typedef name can't be used in elaborated type specifier.

Useing Vs Using Decoding Common Word Mix Ups Declaring new aliases. there are two ways of declaring new type aliases in modern c . the first and traditional one is with the typedef keyword: typedef [original type] [your alias]; for example: typedef int pixel; typedef std::map<std::string, std::vector<std::string>> map; the other one, introduced in c 11, is with the using keyword:. First of all, if you have a c version prior to c 11, then you cannot use the using keyword. hence, if you are maintaining legacy code, typedef would be the way to go. secondly, if you wish your program to be compatible with c, or to be built off c in some way, then you will want to use typedef as well. this is of course, because typedef is a. C using vs typedef. typedef keyword in c is used for aliasing existing data types, user defined data types, and pointers to a more meaningful name. typedefs allow you to give descriptive names to standard data types, which can also help you self document your code. mostly typedefs are used for aliasing, only if the predefined name is too. Example 1: this section draws differences between typedef and using in the context of templates. here, the template <size t n> is the same as the one used in the typedef example 1, which stores the length of the rectangle. instead of using struct, the alias rectangle is assigned to the object dimension through the keyword using.

Now most of the confusion comes from when you add typedef into the mix. if you add typedef to the front of the struct definition like this: typedef struct person {. uint8 t age; char name[50]; } person; this changes the meaning of the word after the }, it now becomes an alias for the struct type, and not the name of a variable as it did above. It involves deciphering the encoded data and converting it into a readable format. on the other hand, encoding is the process of converting information or data into a specific format or code. it involves transforming the original data into a coded form that can be easily transmitted, stored, or processed. while decoding focuses on understanding.
