It’s a good time for existing programmers to leverage their capabilities. This means that existing programmers must upskill and reskill so they can play a broad range of roles. Here are four steps to help you upskill new programmers: Identify skills needed now and later, Ask for your organization’s support, Join bootcamps and online coding courses, Find on-the-job learning opportunities.
Without a big amount of paperwork, a business could not exist. Documentation, important spreadsheets, lists of workers and their private data — all of those could be considered business data of high sensitivity. If any of those files was about to leak, it could lead to massive negative consequences not only for the company itself but also to the well-being of everyone involved. This is why securing your business data is so important.
A pointer can be declared to point to another pointer which points to a variable. Here, the first pointer contains the address of the second pointer. The second pointer points to an actual memory location where the data is stored, i.e. a variable. That's the reason why we also call such pointers as double pointers.

The Standard Template Library (STL) is one of the most essential features of C++. It has very much grown in recent years. Basically, the Standard Template Library provides templatized, general-purpose classes as well as methods. These classes and functions/methods implement several popular and most commonly used algorithms as well as data structures.
The environment in which your code runs is imperfect: users will provide invalid inputs, external systems will go down, and your code and other code around it will often contain some number of bugs. Given this, errors are inevitable; things can and will go wrong, and as a result you can’t write robust and reliable code without thinking carefully about error cases.
