auto sum = sum_integers(integers); std::cout << sum << std::endl; } 我们的目标是使用 C++可执行文件(test.cpp)、Bash shell 脚本(test.sh)和 Python 脚本(test.py)来测试这段代码,以证明 CMake 并不真正关心我们偏好哪种编程或脚本语言,只要实现能够返回零或非零值,CMake 可以将其解释为成功或失...

从这个例子中,可以看出:在同一个输出流对象上(本例为 cout),boolalpha / noboolalpha 设置的状态是持久保留的。以前者为例,只需设置一次,后面遇到 bool 值 输出,均能启作用。 8. “引号” 转义输入:quoted qutoed 的最本质作用,就是允许我们在输入内容中,定义一个特殊字符用于转义,从而改变格式化输入时,将空...
