This statement would assign the product of the expression N1*N2 to the variable PROD. Since the value of a variable can be changed during the program execution, the value of the variable PROD could also change depending on the value stored in any of the two variables N1 and N2
The number 6 there is assigned to the variable X, then in the fourth statement, the variable X is assigned to the variable Y
A variable on the right-hand side of an assignment statement must first be given a value before it can be used in an assignment statement. A variable without an assigned value is called an uninitialized variable
If both expressions (X > 75) and (Y >75) include in the statement evaluate to true (if both X and Y values are greater than 75), then the above statement will evaluate to true , otherwise, the statement will evaluate to false .
If one of the expressions in the statement is true, the statement evaluates to true . This means that if X is equal to either 1 or 3, then the statement is true. For example if, X=4 then the statement above returns the value false
