and a null-character is includedat the end of the new string formed by the concatenation of both in destination. 将源字符串追加到目标字符串后面。目标
Output After concatenation: programming is awesome Here, two strings s1 and s2 and concatenated and the result is stored in s1. It's important to note that the length of s1 should be sufficient to hold the string after concatenation. If not, you may get unexpected output.Share...

不论什么存储 string 的 size 操作结果的变量必须为 string::size_type 类型。特别重要的是,还要把 size 的返回值赋给一个 int 变量。 s1 + s2 Returns a string equal to the concatenation of s1 and s2 把s1 和s2 连接成一个新字符串,返回新生成的字符串 ...
