Mysql外链约束规则
java的mvc三层架构分别是: View(界面层),Service(业务逻辑层),DAO(数据访问层) V:View 网页视图,为用户提供能够看到并且使用的界面,与用户直接进行交互。 M:Model,业务模型,处理业务 C:Controller,控制器,处理请求,调用模型和视图 dao层负责对数据进行直接操控,最底层 service层负责对传递过来的参数验证,以及其他逻辑验证操作。验证完毕访问dao层进行数据操控 servlet层负责接收参数,然后调用service层进行处理 三个层分工合作,有利于后期的功能维护,那层出了问题就去处理哪层

一维数组定义方式为: int a[] = {0,1,2,3,4,5,...}; 或 int a[3] = {0,1,2}; 第一种定义方式没有指定元素数量,第二种固定三个元素进行传参,如果int a[4] = {0,1,2};,那么第四个元素默认是0 二维数组定义方式为: int a[][] = { {1,2,3}, {4,5,6}, {7,8,9} }; int a[][] 代表的是 要定义一个二维数组,=后面的值为二维数组的内容 a[0]输出结果为数组{1,2,3},a[1]输出结果为数组{4,5,6},那么a[0][1]输出为1,a[1][1]输出为4,a[1][1]输出为5 ----------以上是我觉得的---------- 和我学的PHP JS等语言不太一样的数组处理方式,深层逻辑我也不懂。 就以我学的PHP来说,PHP的数组定义: $a = []; 就是定义一个空数组 $a[] = 123; 就是将变量a数组的首个元素指定为123 $a[] = 123;$a[] = 456;将0键值的数据指定为123,将1键值的数据指定为456 --上面是PHP定义一维数组的基本方法-- PHP二维数组的定义方式和C语言也有一样的地方: $a = [ [1,2,3], [4,5,6], [7,8,9] ]; 定义和C语言一样的二维数组 当然也有不一样的地方: $a[0] = [0,1,2]; $a[1] = [3,4,5]; $a[2] = [6,7,8]; 这样定义出来也是一样的二维数组 ----------下面为我个人理解---------- 首先C语言的int a[][] = {{},{}}格式和PHP的$a = [[],[],[]]类似 int a[][] 代表的是 告诉系统要定义一个二维数组,=后面的值为二维数组的内容 而PHP可以直接指定一维数组的键值等于另外一个数组,从而达到二维数组的定义 只是自己做个笔记理解一下两个语言的数组定义方式以及不同,C我也是刚学不久不是很理解,就先写个笔记记录一下了

如果我们想通过一个成绩来得到等级: <span>{{ author.chengji >= 85 ? '优' : '良' }}</span> 可以在标签内渲染一个计算结果达到目的,不过这样会导致运算代码和其他标签内容混淆看起来很臃肿,我们可以通过Vue的计算属性computed来达到分开计算的方法: computed: { chengji:function() { return this.chengji >= 85 ? '优' : '良'; } } ><span>{{ chengji }}</span> 计算属性值会基于其响应式依赖被缓存,如果计算的参数没有发生改变,那么就会直接调用缓存中的结果,而不用再次调用函数获取结果 如果使用methods方法来计算的话,每当数据改变时页面会重新渲染,全部函数将全被执行
ASCII 打印字符 (字符编码: 32-127) 32~126(共95个)是字符:32是空格,其中48~57为0到9十个阿拉伯数字,65~90为26个大写英文字母,97~122号为26个小写英文字母,其余为一些标点符号、运算符号等。第127个字符表示的是键盘上的删除命令。 32-127ASCII码对应值在下方
Python常用的循环函数是 while 和 for 先说明while循环的格式 while 循环条件: 代码段 如: i = 10 while i > 0: i-=1 print(i) 将会依次打印出9 - 0 for循环也是类似: for 临时变量 in 目标对象: 代码段 如: for i in [0,1,2,3]: print(i) 将会打印出数据集内全部数据 当然也可以依次遍历字符串如: for i in "Python Go": print(i) 将会依次打印单个字符结果 死循环用法: while True: 代码段 另外可以用: while(循环条件) 以及 for(i in "Python")这种用括号包含条件的方法

在component目录下新建一个子组件 然后在父界面使用import绑定子界面: import child from "../../component/child.vue" child 是子组件名,from后面连接组件路径 然后使用components绑定组件: components: { child } 父传子参数可以通过标签属性传递: <child :content="content"></child> 子组件接收方法: props: ["content"] 子组件传递参数给父组件: 可以使用this.$emit通过事件的方式传递参数: but:function() { this.$emit("buts",this.putInfo); } buts 父组件接收的事件名, putInfo 是传递的参数 父组件通过标签属性的方式得到传递的参数: <child @buts="buts"></child> 夫组件通过buts事件接收 约束传递的参数: props: { content:{ type: [Number,String], } } 允许Number类型和String类型
首先常用的格式化输出有: 使用 % 占位符输出,常用的占用符可以在贴图中查看 用法: name = "Chumo" font = "My Name Is %s" print(font % (name)) 这里用的是%s字符串占位符,string的首字符s 使用%d输出整数: age = 19 font = "今年%d岁" print(font % (age)) 多个参数用法: name = "Chumo" age = 19 font = "我是%s今年%d岁" print(font % (name,age)) 上面就是基本的占位符输出用法 接下来就是使用 format 格式化 用法: age = 19 font = "今年{}岁" print(font.format(age)) 扩展:使用位置和关键字参数 print('我的名字是 {0}, 我的年龄是 {1}'.format(name,age)) print('我的名字是 {name}, 我的年龄是 {age}'.format(name="Chumo",age=18)) 上面是基本的format格式化输出方法 然后是 f-string 格式化输出方法 用法: name = 'chumo' age = 18 print(f'我的名字是 {name}, 我的年龄是 {age}') 要注意print函数中的 f 字符,在输出内容前加一个f字符,就可以直接将变量在字符串中调用{name} 上面是三种常用的格式化输出变量方式 接下来就是输出字符保留N位小数点方式: 首先说的是 % 占位符输出保留小数点的写法,首先保留小数点肯定是需要一个浮点型的数据,这边浮点数据用的是%f也就是float的首字符f来表示: name = 'chumo' age = 18.43 print(f'我的名字是 {name}, 我的年龄是 %f' % (age)) 输出结果为:我的名字是 chumo, 我的年龄是 18.430000 默认是保留小数点后面6位数据,怎么让他只保留两位呢? 我们可以用 %.2f 的方式保留两位小数: name = 'chumo' age = 18.43 print(f'我的名字是 {name}, 我的年龄是 %.2f' % (age)) 最后输出的结果为:我的名字是 chumo, 我的年龄是 18.43 想要保留更多小数可以在%.2f中修改数字大小来实现:%.3f就是保留三位 接下来就是format函数保留小数点的方法: age = 18.43 print('我的年龄是{:.2f}'.format(age)) 用的是 {:.2f} 保留两位小数的写法 前面的 : 符号是什么意思呢? 其实看下面这个例子就会知道: name = 'chumo' age = float(18.43) print('我的名字是 {name}, 我的年龄是{age:.1f}'.format(name=name,age=age)) 可以看到用的是{age:.1f}的方式输出保留小数点后一位 里面的 : 就是将 age 与后面的小数点长度区分开来 最后是第三种方法f-string格式化(python3.6以后的版本中可以使用) name = 'chumo' age = 18.43 age = round(age,1) print(f'名称{name}年龄{age}') 这种方法我前面介绍过了,是不需要区分数据类型就可以直接进行输出的 需要用到 round 函数处理浮点数保留的位数

讲解if语句之前先讲一下相关的运算符号 编程语言基本运算符号有: "<" ">" "==" "<=" ">=" "!=" 等 我挨个讲解他们的运算逻辑是怎么个实现的 首先是 ">" 运算符他的作用和数学上的 大于 相同,也是作为两个数的大小进行比较,如3>2,3肯定是大于2的,那么将会返回一个真条件,那如果是2>3,那么将会返回一个假条件,在c语言中,1代表真,0代表假,那么就是3>2返回1,2>3返回0 ">" 运算符和小于是相反的,和数学上面的比较方式类似 "==" 运算符在c语言中代表的是 "=" 打个比方就是1==1,将会返回一个真条件,就是1。如果是1==2那么将会返回0 另外的"<="以及">="同等与数学的 大于等于 和 小于等于。 "!=" 运算符表达的是不等于,也就是1!=1返回0,1!=2将会返回1。 上面是运算符------下面是if语句 if语句代表的就是c语言中的条件语句,写法: if(条件) { //条件为真后执行的代码区 } if语句中的条件值得就是上方的运算结果,打个比方: if(10>=9) { //条件为真后执行的代码区 printf("10>=9为真"); } 10>=9因为是正确的,最后会返回1,也就是真条件 接下来就是if中的else语句,写法: if(10>=9) { //条件为真后执行的代码区 printf("10>=9为真"); }else{ //条件为假后执行的代码区 printf("10>=9为假"); } else{}花括号中的代码在假条件时会被执行,但是10>=9是真条件,所以else花括号中的代码永远不会被执行 那么改成这样: if(10<=9) { //条件为真后执行的代码区 printf("10<=9为真"); }else{ //条件为假后执行的代码区 printf("10<=9为假"); } 因为10并不会小于等于9,所以条件为假,最后会执行的是else花括号中的代码,也就是printf("10<=9为假"); 最后就是else if()语句,这个语句代表的是:如果第一个if()中的条件未满足,那么将继续往下判断else if()中的条件是否为真: if(10<=9) { //条件为真后执行的代码区 printf("10<=9为真"); }else if(10>=9){ //条件为假后执行的代码区 printf("10>=9为真"); } 那么就是先判断10<=9是否未真,如果为真将会直接执行if(){}中的代码,如果为假,就会继续向下面的else if()中的条件进行判断是否为真,如果为真就执行else if()中的内容,如果为假则不执行。 当然if,else if以及else都是可以同时使用的: if(10<=9) { //条件为真后执行的代码区 printf("10<=9为真"); }else if(10>=9){ //条件为假后执行的代码区 printf("10>=9为真"); }else{ //上面条件全部为假 printf("上面条件全部为假"); } 这样写法就是当上面的if()以及else if()中的条件全部判断为假后将会执行else{}区块内的代码! ---最后是一点扩展内容--- c语言中的条件语句最后的结果都是0或者1,1==1最后会返回1,1==2最后会返回0,然而if()中写的条件最后也会变成0或者1。 if(1) { printf("条件为真"); } 那么这样写是不是也能执行呢?答案是可以的 我们可以写上两行代码来观测1==1最后返回的结果: int a = (1==1); printf("%d",a); 我这边调试最后打印的结果是1,也就是真条件。所以if()进行逻辑的判断
