Which of these statements are true? a. Any expression can be used as a statement. b. The expression x++ can be used as a statement. c. The statement x = x + 5 is also an expression. d. The statement x = y = x = 0 is illegal.
Given x = 4; and y = 2; and operator = '-' ; what is the final value of x after the following switch statement is executed?
switch (operator) {
case '+' : x +=y ; break ;
case '-' : x -= y ; break ; x += y ; is x = x + y ;
case '*' : x *= y ; break ;
case '/' : x /= y ; break ;
default : break ;
also,
using x = 4 ; and y = 2 ; and operator = ' * '. What is the final value of x?
}
Which of the following statements is correct?
To raise the value of a variable, use increment; to reduce the value of a variable, use decrement.
