和std::print(FILE*, ...)两个重载的优化(不过由于C++26还没有定稿,这一部分可能还会有小改动)。相关提案P3235也迅速获得了通过,最后会说一下。目前这两个提案大概率会变为DR23,见github.com/cplusplus/pa。 Permit an efficient implementation of std::printisocpp.org/files/papers/P3107R5.html C++...
C++标准流输出std::cout一直以来为人们所诟病:不灵活,格式化支持差,冗长等等。人们有此想法源于C库的printf()函数虽然不提供类型安全保障和线程安全保障,...

python std 记录print python输出str 前言 python中转换成字符有两种方法:str()和repr(),这两种又有什么区别?什么时候用str?什么时候用repr? str()函数:将值转化为适于人阅读的字符串的形式 repr()函数:将值转化为供解释器读取的字符串形式 代码示例
对于类成员函数、lambda表达式或其他可调用对象就无能为力了，因此，C++11推出了std::function与std::...
