假设变量C声明如下
null
int *A [10], B[10][10]; |
下面的表达 I A[2] II A[2][3] III B[1] IV B[2][3] 如果在C程序(GATE CS 2003)中用作赋值语句的左侧,哪个不会给出编译时错误?
(A) 一、 仅限II和IV (B) 二、 仅限III和IV
(C) 仅限II和IV (D) 仅限IV 答复: (A) 说明: 请参见下面的解释。
int main() { int *A[10], B[10][10]; int C[] = {12, 11, 13, 14}; /* No problem with below statement as A[2] is a pointer and we are assigning a value to pointer */ A[2] = C; /* No problem with below statement also as array style indexing can be done with pointers*/ A[2][3] = 15; /* Simple assignment to an element of a 2D array*/ B[2][3] = 15; printf("%d %d", A[2][0], A[2][3]); return 0; }
