如何回报这是该指数在字符？ [英] how to return the character which is at the index?

问题描述

我知道，我可以返回一个字符串的indexOf（）函数的特定字符的索引。 但是，我怎么能与特定的索引返回字符？

解决方案

 字符串s =你好;
焦炭C = S [1];
//现在ç=='E'
 

另请参见子串，返回多个字符。

I know that i could return the index of a particular character of a string with indexof() function. But how i could return the character with the particular index?

解决方案

string s = "hello";
char c = s[1];
// now c == 'e'
