在C中查找字符串数组中的字符串数 [英] Find the number of strings in an array of strings in C

问题描述

char* names[]={"A", "B", "C"};

有没有办法找到数组中字符串的数量?例如，在这种情况下，它应该输出:3.

Is there a way to find the number of strings in the array? For example, in this case it should output: 3.

推荐答案

在这种情况下，您可以将总大小除以第一个元素的大小:

In this case you can divide the total size by the size of the first element:

num = sizeof(names) / sizeof(names[0]);

请注意，这适用于数组.它不适用于指针.

Careful though, this works with arrays. It won't work with pointers.
