Nettet24. mai 2024 · in the first iteration s=a [0]=a [3-0] =a [0]+a [3] (and we know that indexing in array starts from 0) = 2+8 = 10 so 10 is printed in first iteration In the second Iteration … Nettet13. sep. 2012 · int i = 2, y = 3, z; z = i++ + y++; //2 + 3 Notice in the last example that it is still 2 + 3. That is because the ++ is after i and y so they are incremented after the = …

NettetThe first oerand ( x && y ) of the expression is equal to 0 because y is initialized by 0 int x = 1, y = 0, z = 5; So the second operand ( z++ ) is evaluated. As result z will be equal to 6. In the second program the initialization expression can be represented the same way as in the first program int a = ( x && y ) && ( z++ ); Nettet首先 int A [2] [3] = {1,2,3,4,5,6};可以写成这样的形式 int A [2] [3] = { {1,2,3}, {4,5,6}}; 这样就看的更清晰了. A 是二维数组名, 在参与运算时候会退化成指针. A这个指针的值和 二维数组中第00个元素的地址一样,即 A == &A [0] [0] (注意这里很重要是在数值上), *A表示第0行的 … is fareway closed on thanksgiving

Nettet28. feb. 2013 · 4 Answers Sorted by: 12 int *ptr = (int*) (&a + 1); // what happen here ? The address of the array is taken, and then 1 is added to it, which produces a pointer pointing sizeof a bytes past the beginning of a. That pointer is then cast to an int*, and that is assigned to ptr. The same could be achieved with int *ptr = &a [5]; in this case. Nettet11. aug. 2024 · A Computer Science portal for geeks.

Nettet首先a [1]是第1行 (从0计数)的首地址。 类型为int *型。 指向a [1] [0] 于是 a [1]+1就是指向a [1] [1] *(a [1]+1)就是a [1] [1]的值, a= 2 4 6 8 10 12 于是a [1] [1]就是8了。 这里有一个通用的公式 对于任意的 * (p+i) 等效于p [i] 7 评论 其他回答 (1) is fareway open christmas eve
