(True/False) 6. In C++, the 5 basic arithmetic operators are addition (+), subtraction (-), multiplication (*), division (/), and exponentiation (). 7. When an arithmetic operator's operands are of different data types, such as automatically converts one of them so that they are the same data type. When a C++ expression is evaluated, unary operations are performed before binary operations. (True / False) (True / False ) int and double, C++ (True / False) 8 9. Since the assignment is an expression, the following code doesn't have a syntax error, and the value of variable (True / False) c is 3 after the execution. int a, b, c; C(a 1) (b 2 ); 10. If a C++ arithmetic expression with one operator has no parentheses, operators are evaluated from left to right. (True / False) (True / False) 11. The escape sequence \n 12. Suppose we declare sum and score an int variables. The statement moves the insertion point to the beginning of the next line. sum /=num 1; is equivalent to the statement sum= sum/num +1". 13.
