- 1. Mark the following statements as true or false. a. An identifier must start with a letter and can be any sequence of characters. (1) b. In C++, there is no difference between a reserved word and a predefined identifier. (1) c. A C++ identifier cannot start with a digit. (1) d. The collating sequence of a character is its preset number in the character data set. (2) e. Only one of the operands of the modulus operator needs to be of type int. (3) f. If ; and ;, then after the statement ; the value of b is erased. (6) g. If the input is 7 and x is a variable of type int, then the statement ; assigns the value 7 to x. (6) h. In an output statement, the newline character may be a part of the string. (10) i. In C++, all variables must be initialized when they are declared. (7) j. In a mixed expression, all the operands are converted to floating-point numbers. (4) k. Suppose . After the statement ; executes, y is 5 and x is 6. (9) i. Suppose .
