Yes very much so! You could learn previous mistakes/bugs/etc and find solutions to fixing them and avoiding getting them. As well as much more. History is always a fun subject for anything, really in my opinion.
/etc/services on my CentOS machine goes up to 49000. Reserved ports are less than 1024.
Well known and reserved ports are two different things. Well known ports only need a registration with IANA. Reserved ports, on *nixes, requires root for a deamon to bind to the port.
Answer:
The answer to this question is given below in the explanation section
Explanation:
The correct answer to this question is: it used a more English-like syntax.
The software developer use high-level language to develop or author the program because it is more likely to English syntax and it would be easy for a software developer to author a program easily instead of using low level language and remembering ones and zeros.
Other options are not correct because:
It can be used on computers without microprocessors: Each computer has a microprocessor either you develop a program using high-level or low-level languages. Changes and modifications are easy in high-level language than in low-level languages. so, the option that prevents anyone from making changes to the software later is wrong. However, high-level languages are less complicated in learning and in authoring the programs but it does not use zeros and ones, it uses English-like syntax. So, the last option is also wrong.
Answer:
d) daco = new Banana;
Explanation:
Dynamically allocated variables have their memory allocated in the heap memory.We declare a dynamical variable like this:-
int *a=new int ;
It means a pointer a is created on the stack memory which hold the address of the block that hold the value of variable a in heap memory.
We already have the pointer daco. We just have to initialize with keyword new.
It will be like daco=new Banana; which matches the option d.
