Explanation / Answer

2)Answer:

&&:

The && operator takes two boolean expressions as operands and creates a boolean expression that is true only when both subexpressions are true. It also performs short-circuit evaluation. If the expression of the left of the && operator is false, the expression on the right side will not be checked.

||:

The || operator takes two boolean expressions as operands and creates a boolean expression that is true when either of the subexpressions is true

3)Answer:

bool

The bool keyword is an alias of System.Boolean. It is used to declare variables to store the Boolean values, true and false. In C# , there is no conversion between the bool type and other types

int

int variables are stored signed 32 bit integer values in the range of -2,147,483,648 to +2,147,483,647

decimal

The decimal keyword denotes a 128-bit data type.The approximate range and precision for the decimal type are -1.0 X 10-28 to 7.9 X 1028

string

The string type represents a string of Unicode characters. string variables are stored any number of alphabetic,

numerical, and special characters

5)Answer:

TryParse. A useful method for parsing integers is the int.TryParse method. The parsing logic in TryParse is the same. But the way we call it is different
