Of course, you use a char -pointer for that, which is guaranteed to be able to address all contiguous bytes. 
当然，您为此使用了char指针，可以保证能够寻址所有连续字节。
You shouldn't read out of allocated bounds, however, which could crash your program runtime or even the OS, depending on the OS. 但是，您不应该读出分配的界限，这可能会导致程序运行时甚至操作系统崩溃，具体取决于操作系统。
Anyways: With a probability towards 1, this is not what you want. 无论如何：概率不是1，这不是您想要的。
