C语言基础: if语句

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

Uni-App学习:Vue中v-bind用法

v-bind主要用于绑定一个或多个属性值，或者向另一个组件传递props值。 <view v-html="html" :style="sty"> data() { return { sty: "background: red;color:#fff" } } 主要写法在上面所示完整写法是v-bind:style="sty"缩写::style="sty" 一般用于绑定标签属性

Uni-App学习:Vue监听属性watch

当监听的数据发生变化时将会执行函数内容 watch: { textInfo:function(newData, oldData){...} } newData代表更新之后的变量信息，oldData代表更新之前的数据信息，textInfo代表的是要监听的对象

51单片机中断函数

关于interrupt函数用法： void +函数名+interrupt +数字0~4 0 表示外部中断0 1 表示定时器/计数器（T0） 2 外部中断1 3 定时器/计数器(T1) 4 串行口 0 一般作为定时器中断使用 4 一般作为串口接收/发送数据用法: void 函数名() interrupt 4

Java StringBuilder基本用法

//StringBuilder类型示例 public class demo3 { public static void main(String[] args) { //StringBuilder 定义的数据是可改变的 //String 定义的数据是不可改变的，每次覆盖都会产生新的变量 StringBuilder strb1 = new StringBuilder("1123"); //必须使用new方法进行赋值，数据存储在堆中 strb1.append("abc"); //使用append在str1后面添加新的数据，类似一个伪数组同样可以通过charAt的方式访问索引 System.out.println(strb1.charAt(5)); //返回5索引的字符 System.out.println(strb1); StringBuilder strb2 = new StringBuilder("ceshi123"); strb2.reverse(); //容器内的数据进行翻转 String str = strb2.toString(); //StringBuilder类型转为String类型，返回String类型数据 System.out.println(strb2); System.out.println(str); } }

Python基础:变量与数据类型

Python定义变量的方法为: name = "chumo" age = 19 也可以同时定义: name,age = "chumo",19 两种方法定义都是一样的结果定义变量时不需要像c语言以及java那样先声明数据类型再写入变量内容。 Python常见的数据类型有: Number（数字） String（字符串） List（列表） Tuple（元组） Set（集合） Dictionary（字典）
