我可以在scanf中使用指针来接受数组中的输入吗? [英] Can i use pointer in scanf to take input in an array?

问题描述

我正尝试在 c 的问题中进行此操作:

I am trying to do this in c:

scanf("%d",a+i);

其中，a是大小为10的数组.并且i是循环计数器.那有可能吗?

where a is an array of size 10. And i is counter for loop. So is this possible?

推荐答案

:如果a是int*或数组int a[10]，并且i在0到9之间，则此表达式有效.

Absolutely: if a is an int* or an array int a[10], and i is between 0 and 9, this expression is valid.

a+i表达式与&a[i]等效，它也是传递给scanf的有效表达式.

The a+i expression is the pointer arithmetic equivalent of &a[i], which is also a valid expression to pass to scanf.
