1.The symbol & denotes the logical or-operator?
2.The symbol ~ does not denote the logical negation-operator?
3.An expression value of 5 is interpreted as true?
4.The symbol == can be used for assignments?
5.MATLAB is a compiler language?
6.More than one statement can be executed from single command line?
7. fprintf('%c','c'); , is a proper MATLAB statement?
8. y=12%3; stores the value 4 in location with name y?
9. y=(4==4); stores the value 4 in the location with name y?
10.Whatever can be accomplished with a for loop can also be accomplished with a while loop?
11.To close and save an open file on disk from a program the statement fclose(fname) is necessary?
12.The symbol %f is called a conversion control sequence?
13.The exponential notation 1.2e3 is identical to the scientific notation 1.2x e^3?
The questions are True or false . These are some of the questions I was not really sure about. Any help would be truly appreciate.
Thanks
John

What is a "a compiler language"? A language that can create programs that are capable of being compiled as an executable? Or did you mean "a compiled language"? Meaning one that needs to be compiled before it can even be run, as opposed to an interpreted language?

My bad, what I meant was "compiled language". Which indeed is a true statement. MATLAB is a compiled language. Thank you for your comment.

6 false, 4 true, and 3 "sometimes".
You can look some of these up directly in the documentation. For example, you can search for
& operator

Information about assignment operators is a bit difficult to find, but see http://www.mathworks.com/help/matlab/ref/specialcharacters.html

I directed you towards resources that will allow you to determine the answer for yourself. And remember, you can always just type some of them into MATLAB and see what happens.
