function1 // functions1.rs // Make me compile! Execute `rustlings hint functions1` for hints :) fn call_me fn main() { call_me(); } 函数遍布于Rust中，用fn声明。Rust代码中的函数和变量名使用snake case规范风格。与C不同，Rust不关心函数定义于何处，只要定义了就行。上述是缺少对函数的定义。我们观察到call_me()没有参数。 fn call_me() { print!("123!"); } 其实函数的完整形式为 fn call_me() -> () { print!("123!"); } 如...

指令(MIPS-32)(working) 计算机语言中的基本单词就是指令。 各种语言的指令集能体现出一定的相似性，因为所有计算机都是基于基本原理相似的硬件技术所构建的。计算机设计者致力于找到一种语言，既能方便硬件和编译器的设计，使性能达到最佳，又使成本和功耗最低。计组读了很久，沿着书中的习惯，详细的了解该指令集。 冯诺依曼体系结构 五大功能部件 输入设备 输出设备 运算器 控制器 存储器：存储数据结构，下标从0开始的一维数组(抽象) MIPS-32指令集概况 32个寄存器，大小为32位。 2^30个存储器字，32位为一组。 字节编址，故需要遵照对齐限制(数据地址与存储器的自然边界对齐的需求)。 采用大端编址 单位与约定 ...
