1 用于处理短字符串的字符串性能 - std::string performance for handling short strings
2014年12月24 - Bjarne Stroustrup and other experts said that C++ is faster than C for handling for short strings in Bjarne Stroustrup' article and my previous
2 GCC中的std :: string实现及其短字符串的内存开销 - std::string implementation in GCC and its memory overhead for short strings
2011年02月20 - I am currently working on an application for a low-memory platform that requires an std::set of many short strings (>100,000 strings of 4-16
3 源码阅读笔记 - 3 std::stringShort String Optimization
2016年04月30 - 。 正因为这样,我们想组合两者的优势,既要享受堆空间的自由,又想要在数组较小的时候使用栈空间来加快速度,并且结合两者不会产生额外的开销,这时候,我们需要Short String Optimization (SSO). 一个 std::string 一般情况下把字符串存在堆空间,这样的效果就像你使用 new
4 性能比较:strstr() vs std:::string::find() - Performance comparison: strstr() vs std::string::find()
2012年08月03 - Can someone please explain why I should use strstr or string find() ? Which one is faster, at where ? 有人能解释一下为什么我要使用strstr或string find()吗?哪一个更快,在哪里?
5 字符向量:为什么单个元素不是std::string ? - Rcpp CharacterVector: why aren't individual elements std::strings?
2014年04月25 - this might be a stupid question but i thought that each individual element of a CharacterVector would be a std::string. However, this doesnt work: 这可
6 为什么“自动”将字符串声明为const char*而不是std: string? - Why does “auto” declare strings as const char* instead of std::string?
2014年01月01 - can't (or doesn't) the compiler declare those strings automatically std::string? 为什么编译器不能(或不)自动声明那些字符串std::string?
7 性能挑战:整数到std::字符串转换。 - C++ performance challenge: integer to std::string conversion
2010年12月04 - Can anyone beat the performance of my integer to std::string code, linked below? 是否有人能将我的整数的性能打到std::字符串代码,链接在下面? There are already several
8 std::字符串转换为大写:主要性能差异? - Converting std::string to upper case: major performance difference?
2012年02月29 - that the two would be somewhat similar performance-wise, but I was terribly wrong. Now I'd like to find out why. 所以我在玩一些代码,想看看哪种方法可以转换std::string to upper case
9 std :: map和performance,相交集 - std::map and performance, intersecting sets
2009年06月29 - 。 I'm finding the performance be very slow. 我发现性能非常慢。 Details: - One of the sets has 150,000 numbers in it - The intersection of that set and another
10 如何在使用键类型std::string的映射查找中提高性能? - How can I increase the performance in a map lookup with key type std::string?
2008年11月01 - 。 The key type is an std::string. 关键类型是std::string。 Can I increase the performance of this std::map lookup via a custom key compare override for the map
