1. Mark the following statements as true or false The order in which statements execute in a program is called the flow of control In Ct+,-, is the equality operator In a one-way selection, if a semicolon is placed after the expression in anif statement, the expression in the if statement is always true. Every if statement must have a corresponding else The expression in the if statement: if (score 30) b. c. d. e. grade -"A" always evaluates to true. The expression: (2, 5) (ch >= 'A, && ch> num if (num> 5) f. g. cout 0) is true only if x is a negative number j. In C++, both! and !- are logical operators k. The expression in a switch statement should evaluate to a value of the simple data type. 2. Suppose that x, y, and z are int variables and x 13, y 45, and z - 20. Determine whether the following expressions evaluate to true or false. a. !(x-y
