字符数组是以‘\0’结尾的,所以在字符数组赋值给字符串时会多出来一个’\0’。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 char a[]="mynameis" string b=a; cout<<b<<endl; 此时输出结果应为mynameis,然而输出结果为mynameis口(空字符标志打不出来); 所以用字符数组给string赋值时要用assign() ...

但是,正如注释说的,这里直接使用了 medium strings 的存储方式。 比如folly/io/IOBuf.cpp 中的调用: // Ensure NUL terminated*writableTail() =0;fbstringstr(reinterpret_cast<char*>(writableData()), length(), capacity(), AcquireMallocatedString()); 字符串拷贝 同初始化,也是根据不同的字符串类型,调用...

The class is found in src/corelib/tools/qstringbuilder.cpp if you want to have a look at it. QStringBuilder uses expression templates and reimplements the '%' operator so that when you use '%' for string concatenation instead of '+', multiple substring concatenations will be postponed ...
