In this world of SAP programming, ABAP is the universal language. in most of the projects, the focus is on getting a team of ABAP programmers as soon as possible, handing over the technical specifications to them and asking them to church n out of the ABAP programs within the "given deadlines ".
Often due to this pressure of schedules and deliveries, the main focus of making a efficient program takes a back seat. an efficient ABAP program is one which delive

I sorted out the skills and suggestions I encountered in the C ++ project code.0x00 uses macro definition.It is often seen that programmers use the enum value to print the debugging information and want to print the character meanings of numbers. I have seen someone write this Code if (today = MONDAY) return "MONDAY"; generally, there are many error codes. switch-case sho
some code that can be used to parse the ISO-8601 date string, and simply rewrite it to use it.Well, just use C to make it look good, but do you believe that we have a better plan!If you can control the date format you are working with, try to choose a Unix timestamp. You can easily convert from timestamp to NSDate:-(nsdate*) Datefromunixtimestamp: (nstimeinterval) timestamp {return [nsdate Datewithtimeintervalsince1970:timestamp]; }This will be faster than using C to parse the date string!It is

built into other standards. As a standard, its handling of data is irrelevant to the programming language (which can be an advantage or a disadvantage, but at least it makes the way we work with data consistent). DOM is now built not only into Web browsers, but also as part of many xml-based specifications. Now that it's a part of your tool and maybe you'll use it occasionally, I think it's time to take advantage of the functionality it brings to us.
After using the DOM for a while, you'll see
