步骤二:实现JNI函数 我们需要编写一个 JNI 函数,该函数将 C++ 的string类型数据传递到__android_log_print中。以下是一个示例代码: #include<jni.h>#include<string>#include<android/log.h>#defineLOG_TAG"NativeLog"#defineLOGI(...)__android_log_print
program main implicit none interface subroutine print_string(str) bind(C,name='c_print_string') use ISO_C_BINDING, only : C_CHAR character(kind=C_CHAR),dimension(*) :: str end subroutine print_string end interface call print_string("haha-c_print_string") end program main windows11+power...

下面是来自cppreference.com关于std::print()的介绍:支持Unicode 编码的std::print系列函数可对已格式化的文本执行格式化 I/O。它们具有 std::format 的所有性能优势,默认情况下与语言环境无关,减少全局状态,避免分配临时 std::string 对象和调用运算符 <<,并且与 iostreams 和 stdio 相比,通常使格式化更高效。
const std::string& getFirmwareVersion() const { return m_ecuFirmwareVersion; } so that I can print the m_ecuFirmwareVersion which was declared like so: std::string m_ecuHardwareVersion; here is my print method: cout << printf("\nThe version is: %s", NovariantModule::getHardwareVersion...

mytuple1<int,float,string>t(41,6.3,"nico");print1(t1.head(),t1.tail().head(),t1.tail().tail().head()); 上述继承关系可以表示为如下结构: tuple还有一种递归组合的实现方式, 也列出来, 有兴趣的朋友也可以看看: 代码语言:javascript

prefix can be a string, like >>> from icecream import ic >>> ic.configureOutput(prefix='hello -> ') >>> ic('world') hello -> 'world' or a function. >>> import time >>> from icecream import ic >>> >>> def unixTimestamp(): >>> return '%i |> ' % int(time.time()) ...
