Suppose that alpha and beta are int variables and alpha = 5 and beta = 10. After the statement alpha *= beta; executes, ___. alpha = 5 alpha = 10 alpha = 50 alpha = 50.0 The escape sequence \ r moves the insertion point to the beginning of the next line True False Suppose that alpha and beta are int. variables. The statement alpha = --beta; is equivalent to the statement(s) __. alpha = beta -1; alpha = beta; beta = beta -1; beta = beta -1; alpha = beta; alpha = 1 -beta
