问题 单项选择题

下列二维数组初始化语句中,不正确的是( )。

A.int b[][2]={1,2,3,4,5,6,7};

B.int b[3][5]={0,0,0};

C.int b[][4]={1,2},{3,4,5},{6}};

D.int b[3][2]={(1,2),(3,4),(5,6)};

答案

参考答案:D

解析: 在对二维数组元素赋初值时,可以只对部分元素赋初值,未赋初值的元素自动取0;C语言规定,对于二维数组,只可以省略第1个方括号中的常量表达式,而不能省略第2个方括号中的常量表达式;赋的初值不能多于事先定义好的数组元素个数。选项D赋值表达式中对每一维的元素赋初值应用{},而不是0。
