  • 第1题:

    下列语句中,句法错误的是(不考虑语义)( )

    A.while(x=y)5 ;

    B.do x++ while(x==10) ;

    C.while(0);

    D.do 2;while(a==b);


    正确答案:B
    while语句的一般形式是:while(表达式)语句这里的表达式可以是任何合理的表达式,语句可以是任何语句,包括空语句,或表达式语句。可能书写的while语句没有任何意义,如供选择的A.while(x=y)5;和C.while(0);,但这两个语句的句法没有任何错误。do-While语句的一般形式是:do语句while(表达式);其中的成分语句也可以是任何语句,但供选择答案B.dox++while(x==10);中的代码x++是一个表达式,不是语句,所以是错误的。正确解答是B。
