如何获得字符串的第n个字符? [英] How can I get the nth character of a string?

问题描述

我有一个字符串，

char* str = "HELLO"

如果我只想从中获取E，我该怎么做?

If I wanted to get just the E from that how would I do that?

推荐答案

char* str = "HELLO";
char c = str[1];

请记住，C中的数组和字符串从0开始而不是从1开始索引，因此"H"为str[0]，"E"为str[1]，第一个"L"为str[2]，依此类推.

Keep in mind that arrays and strings in C begin indexing at 0 rather than 1, so "H" is str[0], "E" is str[1], the first "L" is str[2] and so on.
