char字符类型 float、double浮点类型 复合类型 void 函数无返回值时,声明为void类型。 不能将一个变量声明为void类型。 整型 对于int关键字,可用如下修饰关键字进行修饰: (1) 符号性: signed 带符号 unsigned 无符号 (2) 大小: short long long long Cpp 标准保证: highlighter- Java 1== sizeof(char) <= ...

注:能依赖声明的就丌要依赖定义。 3.内联函数 叧有当函数叧有10行甚至更少时才会将其定义为内联函数(inlinefunction)。 定义(Definition):当函数被声明为内联函数乊后,编译器可能会将其内联展开,无需挄通常的函数调用 机制调用内联函数。 优点:当函数体比轳小的时候,内联该函数可以令目标代码更加高效。对亍存...
