执行以下程序段后，W的值为______。 int w='A',x=14,y=15 w=((x‖y)&&(w＜'a'));
A．-1
B．NULL
C．1
D．0
参考答案：C
解析：[评析] 本题考查的是括号与逻辑运算符的混合运算，其运算优先级为先括号，后逻辑运算符。另外注意“&&”和“||”的“短路”运算。当运算符“&&”左边表达式的值为0时，则右边表达式就不再进行运算，整个表达式的值即为0；当运算符“||”左边表达式的值为非零时，则右边表达式就不再进行运算，整个表达式的值为1。本题先运算表达式“x||y”，由于x=14、y=15均为非零，所以x||y=1。则对于与运算符“&&”，还必须运算其右边的表达式“w＜'a'”，由于A的 ASCII码是65，a的ASCII码是97，所以w＜'a'的值为1，故整个表达式的值为1。
