## Project Level ## I ncludes #include int main() { std::cout << "Hello, world!" << std::endl; } ## I ncludes ## #include ~69,000 Lines! int tooling Frowned upon for entities defined in another project - Can obfuscate dependencies ## - Include What You Use ## - IWYU Project ## Templates template struct Sum { static const int template <> struct Sum<0> { static const int value = 0; }; ## Templates #include template struct Sum { static const int value = N + Sum::value;

ssize_t，可以用 intptr_t 代替。 ## 实验：各种标准化类型的大小 • 我们可以通过 `sizeof(T)` 获取 T 类型的字节数。 main.cpp #include #include int main() { printf("uint8_t = %ld\n", sizeof(uint8_t)); printf("uint16_t short 后是 00000000 10000000 - 可见 short 的前一个字节被填满了 0，根据补码的规则他是一个正数 128。 1main.cpp 1 #include 2 #include 3 4 int main() { 5 unsigned char x = -128; 6 short y = (short)x; 7 相加会得到什么类型？会得到 int 类型。 • 结论：小类型和大类型做数学运算（ $ +-*/\% $ ）会得到两个类型中的大类型。 main.cpp #include #include #include int main() { static_assert(std::is_same
