Logic error

Types of program errors. We distinguish between the following types of errors: Syntax errors: errors due to the fact that the syntax of the language is not. Everybody makes mistakes while programming and finding mistakes in Finding a problem in a small and easy piece of code is much simpler than trying to.

Or someone finds a new way to crack a particular algorithm which renders that algorithm useless. So you need to constantly keep abeast of developments in cryptography and update your code if it is still in use if vulnerabilities and hacks are discovered in the algorithms you use. For example, SHA-1, which is a hashing algorithm, is no longer recommended for computing hashes. So if your code uses SHA-1 at any point, you will need to replace it with the recommended one if the software is still being used. Otherwise you run the risk that your application is open to attack.

Programming software and the IDE

Recently, I have given a company exam, in the coding domain, some of the parts were locked and other were unlocked to write the logic. I wrote the statement: My question is how to return an array from a function? Which part of the statement is wrong? Are you aware that memory allocated in these languages need to be freed? Does that not make it manual, as opposed to being garbage collected like in Java?
