有以下程序： main() { char a,b,c,*d; a='\';b='\xbc'; c='\0xab';d="\017"; printf("%c%c%c\n",a,b,c,*d); } 编译时出现错误，以下叙述中正确的是( )。

A．程序中只有“a='\';”语句不正确

B．“b='\xbc';”语句不正确

C．“d="\0127";”语句不正确

D．“a='\';”和“c='\0xab';”语句都不正确

答案

参考答案：D

解析：语句a='\'是错误的，因为\是转义字符，应该用\\来表示，语句“B='\xbc';”是正确的，它是将一个用十六进制表示的转义字符赋给一个字符型变量；语句“c=\0xab;”是错误的，反斜线后的十六进制只可由小写x开头，不能用0x。语句“d="\0127";”是正确的，可以给字符型指针变量赋一个字符串常量，其作用是让该指针变量指向该字符串常量。所以，D选项为所选。
