Answer1. Benefits of separating header files from the cpp files ar.pdf
- 1. Answer 1. Benefits of separating header files from the cpp files are: a. reusability, as header files are most commonly used files included in the cpp files, they are inclusively used for almost all the functions. To avoid mentioning them again and again in each and every files in a project they are separated from all the cpp files and are clubed together in a single header file which is used during the execution of the project and and is linked with the other cpp files during the runtime. b. compilation becomes faster, as linking will be needed only once unlike each time for each cpp file c. organized code, header file acts similar to book index and helps you to locate specific function d. helps in separating interface from implementation 2. It's not that a programmer should minimize the use of #include in header file, they need to be careful while using #include in the header file and always use them within the #ifnotdefined and #ifnotdefinedend block in order to avoid clash and error of multiple inclusion. 3. include guard... guard against multiple incidental includes it is needed to prevent multiple inclusion error 4. const is the keyword for making any value/element constant. Example: const int a = 5; const int *p; etc. Solution Answer 1.
