Mark the following statements as true or false:

a. The result of a logical expression cannot be assigned to an int variable.

b. In a one-way selection, if a semicolon is placed after the expression in an if statement, the expression in the if statement is always true.

c. Every if statement must have a corresponding else.

d. The expression in the if statement:

if (score = 30)

grade = 'A';

always evaluates to true.

e. The expression:

(ch >= 'A' && ch <= 'Z')

evaluates to false if either ch < 'A' or ch >= 'Z'.

f. Suppose the input is 5. The output of the code:

cin >> num;

if (num > 5)

cout << num;

num = 0;

else

cout << "Num is zero" << endl;

is: Num is zero

g. The expression in a switch statement should evaluate to a value of the simple data type.

h. The expression !(x > 0) is true only if x is a negative number.

i. In C++, both ! and != are logical operators.

j. The order in which statements execute in a program is called the flow of control.
