原创数据类型相关笔记

C、C++、java强调类型；JavaScript、python、php不看重类型，甚至不需要事先定义。

原创 for循环语句

count>0;count–)可以理解成：“对于一开始的count=10，当count>0时，重复做循环体，每一轮循环在做完循环体后，使得count–”PS：break和continue只能对所在循环进行操作。小套路● 求和时，变量初始值为0；● 求积时，变量初始值为1。

原创整数逆序处理

变量%10000/1000 ——>千位 12345%10000=2345 2345/1000=2。变量%1000/100 ——>百位。● 输入一哥正整数，输出逆序的数；变量%100/10——>十位。变量%10/1 ——>个位。如果X=700 输出007。● 结尾为0进行处理。

原创 while循环语句

while循环的意思就是：当条件满足时，不断的重复循环体内的语句。思路：数据除以10，一位一位划掉。

最近在调试STM32ADC采集NTC热敏电阻的温度值，总结下NTC热敏电阻温度值的采集方法。硬件平台：STM32F205软件平台：keil V5函数库：标准库本例中使用的热敏电阻型号为mfh103-3950。其电阻与温度对应表如下：热敏电阻的采样电路图如下图：从上图电路原理可知，温度上升，NTC阻值下降，对应的ADC采样电压下降，j进而AD采样值下降。即每对应一个温度值，就对应一个ad采样值，这样便可得到一个温度与ad值的对应表。　　那么NTC采集温度的原理就是利用采样的ad值与对应表进行比较，
