Question
Coding This program by using C++ coding in template class required3 file one of the file is header. Suppose that you implement a sequence where the value_type has a comparison operator < to determine when one item is less than another item. For example, integers double numbers, and characters all have such a comparison operator ( and classes that you implement yourself may also be given such a comparison). Rewrite the sequence. In a sorted sequence, the insert function always inserts a new item so that all the items stay in order from smallest to largest. There is no attach function. All the other functions are the same as the original sequence class
Explanation / Answer
You have a file containing the declaration of a class with all class members. You place #include guards around this file (or #pragma once) to ensure no conflicts arrise if you #include the file in two differentheader files which are then included in a source file. You compile a separate source file with the implementation of any methods declared in this class, as it off loads many lines of code from your source file, which cleans things up a bit and introduces some order to your program.
Example: As you can see, the below example could be improved by splitting the implementation of the class methods into a different file.
Perhaps this is the main reason why you would split implementation from declaration. In the above example, you could move the method body to outside the class. This would make it look much cleaner and structured. However, according to this question, the above example has implicit inline specifiers. Moving the implementation from within the class to outside the class, as in the example below, will cause you linker errors, and so you would either inline everything, or move the function definitions to a .cpp file.
Example: _The example below will cause "multiple definition linker errors" if you do not move the function definition to a .cpp file or specify the function as inline
