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,...
最后,我们就可以import,启动!创建<project_root>/main.cpp: importstd;automain()->int{std::println("Hello, world!");} 然后就可以配置和编译了: mkdir build cmake -S <project_root> -B build -G Ninja -DCMAKE_CXX_COMPILER=<install_prefix>/usr/local/bin/clang-18 ...
