Open the Jacobson Solution. sln file contained in the VB2017/Chap03/Jacobson solution folder. Enter the three Option statements in the code editor window. Code the btnCalc_Click procedure using variables and a named constant. Display the sales tax with a comma (if necessary)and two decimal places. Display the total due with a comma (if necessary), a dollar sign and two decimal places. Save the solution and then start and test the application. (If the sales amount is 500, the sales tax and total due are 25.00 and $525.00, respectively.)

The three logical operators used to write compound conditions are "and," "or," and "not." a: true b: false

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why.a.) student.course.callnum = "csc230"; b.) cin > > student.name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student.name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist.course.credits = 3; j.) course = studenttype.course;
