Answer:
d) y=x++
Explanation:
In all 3 statements:
y= ++x;
y=x=5;
y=5;
The value of y is equal to 5.
However in the statement y=x++, the value of 5 is equal to value of x prior to the increment operation. The original value of x was 4. So the value of y will be 4. Note that after the statement execution, the value of x will be updated to 5. In effect y=x++ can be visualized as a sequence of following steps:
x=4;
y=x;
x=x+1;
Answer:
High level language.
Explanation:
High level language can be defined as a programming language which is generally less complex than a machine (low level) language and easy to understand by the end users (programmers).
This ultimately implies that, a high level programming language is typically a user friendly language and as such simplifies coding or programming for beginners.
Some examples of high level programming language are Python, Java, C#, Ruby, Perl, Visual Basic, PHP, Cobol, C++, Fortran, Javascript, etc.
In this scenario, Huzaifa is a grade 5 student who is very enthusiastic to learn coding in computers. He asks his computer teacher to help him choose a language to code. Thus, the language level the teacher will recommend to Huzaifa is a high level language.
I would suggest the use of a
disk quota.
Using a disk quota would limit the available space that
users could have used to store data. The New Technology File system (NTFS) has
several features like disk quotas to see which users are uploading the most
space. The windows interface Open
Computer Management is also another option that limits the number of users of a
shared folder.
