Question

For each of the following questions, circle T (true) or F (false). FORTRAN was developed primarily for accounting and business applications C# is a language developed by Microsoft and was based on Java and C ++. BNF notation for syntax is more powerful than the EBNF notation. Every attribute grammar can be rewritten as a BNF grammar with possibly more non-terminals and more rules. Every BNF grammar G that has left recursion can be converted into a grammar G^' that recognizes exactly the same language and has no recursive rules in it. A grammar G is ambiguous if there is more than one parse tree for every sentence in the language defined by G. In most programming languages that have infix operators. +,-,* and / are left associative. A lexical analyzer reads a stream of tokens and produces a parse tree. Syntax analysis is about discovering structure in text and is used to determine whether or not a text conforms to an expected format. All algorithms represented by flowcharts can be coded with only two control statements: one for choosing between two control flow paths, and one for logically controlled iteration. double u = 1.0; int w = u; The second statement needs a casting. An application named Find Avernge.jar is not an executable file. An application named CalculateBMI.py. Its source code is not available. Fill the following blanks. Five examples of primitive data types in C# (or C++, or Java) are: If we construct an object of type Foo as defined by class Foo{int x=5; int y= 1; Foo(){x=2;}}, the value of x in the new object will beand the value of y will be. Three examples of unary operator in C# (or C++, Java) are:and A method whose purpose is to create instances of a class is called aAttributes of a variable are:

Unary Plus, Unary Minus, Increment and Decrement operator are unary operators in Java

We can create instances using "new" and "clone" method.

aligned, mode, nocommon, packed, section are the five attributes of a variable.
