Jni中 java函数转C函数 该方法需在已安装NDK环境下,才可使用 新建一个java类,并添加方法,如下 鼠标点击open函数,键盘同时按住Alt 和回车键,再选择Create Jni function for open(有cpp文件时才可使用),就会自动在Cpp文件内自动生成java转C的函数...
输入即给程序提供数据,cin对象将标准输入表示为字节流。通常情况下,通过键盘来生成这种字节流。cin对象会从输入流中抽取字符,输入可以是各种类型,所以抽取还设计了类型转换。 cin会根据接受值的变量的类型,使用其方法将字符序列转换为所需的类型。调用方式如下: ...

cin.get()存在的基本目的,我认为就是为了从c移植到c++的时候,直接用cin.get()代替getchar(),也正因因此,cin.get()的返回值跟其它cin.get成员函数返回cin对象不同,跟getchar()一样返回int。所以cin.get()和C语言的getchar()没什么区别。 voidtest_input(){charch1,ch2; ...
