2、字符串字面值不能直接相加,字符串字面值和string是不同类型的,字符串里面没有空字符'\0'。(更新于2014.06.24)】 s1 = s2 Replaces characters in s1 by a copy of s2 把s1 内容替换为 s2 的副本 【备注:。它必须先把 s1 占用的相关内存释放掉,然后再分配给 s2 足够存放 s2 副本的内存空间,最后把...

一、问题描述：从键盘输入一个字符串给str和一个字符给c，删除str中的所有字符c并输出删除后的字符串str。1、输入：第一行是一个字符串； 第二行是一个字符。2、输出：删除指定字符后的字符串。二、设计思路：1、 同插入问题，定义两个字符数组a，b。以及标志删除位置的int型pos。2、用gets函数...
1.1 单字节字符集(single-byte character set(SBCS)) 顾名思义,在这种模式下,所有的字符都只用一个字节表示,常见的如,ASCII 1.2多字节字符集(multi-byte character set(MBCS)) 在Windows中MBCS包含两种字符类型,单字节字符和双字节字符.由于windows使用的多字节字符绝大部分是两个字节长,所以MBCS常被DBCS代替。

Similarly to the previous, due to related changes in string parsing, adjacent string literals (either wide or narrow character string literals) without any whitespace were interpreted as a single concatenated string in previous releases of Visaul C++. In Visual Studio 2015, you must now add whitesp...
