我刚刚被介绍了have文件(用于c++程序),我有三个简单的问题。假设我有一些类定义存储在functions.h中,它的定义在functions.cpp中定义,它的实现在main.cpp中定义。我的简单makefile是: ${CXX} -o main student.o main.o rm -f如果它们不存在,那么makefile会<e 浏览0提问于2018-04-11得票数 2 1回答...
例如,add_executable(hello main.cpp)会定义一个名为hello的目标,这个目标由main.cpp这个源文件生成。在生成的Makefile中,这个命令会被翻译成一个编译命令,如$(CXX) $(CXXFLAGS) -o hello main.cpp。这条命令告诉make工具使用C++编译器(( C X X ) )和编译选项( (CXX))和编译选项((CXX))和编译选项((CX...

A Study On File Input Output Operations & File Pointer Functions In C++. In real-time programming, we deal with large chunks of data that cannot be accommodated from standard Input-Output devices. Hence we need to make use of secondary storage for storing data. Using secondary storage we usua...
