As noted in Figure 6.1, Fortran and Pascal give unary and binary minus the same level of precedence. Is this likely to lead to nonintuitive evaluations of certain expressions? Why or why not? In Example 6.9 we described a common error in Pascal programs caused by the fact that and and or have precedence comparable to that of the arithmetic operators. Show how a similar problem can arise in the stream-based I/O of C++ (described in Section C 8.7.3). (Hint: Consider the precedence of <>>, and the operators that appear below them in the C column of Figure 6.1.)
