小庄读书 软件从业者,偏爱文史书。 都说“指针”是C语言的灵魂,但是其实C语言的源代码看的多了之后你就会发现,C语言源代码里面经常会有大量的“宏”,各种宏定义、宏指令——“宏”,或者更准确的说“预处理指令”,也可谓是C语言编程的一大“利器”～～预处理指令很强大,可以做很多事情,常见的比如:*#include引入...
3. 当计算struct或class的大小时,除了需要考虑基本数据类型的大小,还要特别注意字节对齐问题。对于C++而言,还需考虑虚函数的虚表问题,需要加上虚表指针的大小。资料参考CS_DN「Zmyths」呀,感谢大家一起加油呀。 #编程 #大一新生 #计算机专业 发布于 2023-10-11 22:58・IP 属地广西 赞同2 分享...

government, education, nonprofits — they’ve all designed really fascinating careers that really play into their passions and their interests. So I find that very inspiring, the way in which they’ve taken the resources and education given to them and used it to make the world a better place...
