Variables declared in the BSS section don't actually take space, unlike in the data segment.
与数据部分中不同，BSS部分中声明的变量并不实际占用空间。
BSS stands for "block storage segment" (originally, "block started by symbol"), and the memory reserved in the BSS section is initialized to zero during the start of the program.
BSS代表“blockstoragesegment”(原来是以一个符号开头的块)，BSS部分中保留的内存在程序启动时初始化为零。
