当增量运算符放在变量的左侧时，它将首先将变量的值增加1，然后在表达式中使用它。
什么是输出？使用printf()打印的内容可以叫作输出。
#include <stdio.h>
int main()
转义序列\\n告诉程序添加一个新行。看看以下程序声明。下表描述了一些常见的转义序列。
以下代码段生成三个单独的行，只有一个printf()函数。
#include <stdio.h>
int main(){
\\t转义序列对格式化输出很有用。以下代码在输出中创建列。
#include <stdio.h>
转义序列\\r将光标移动到行的开头。

操作
必需的控制字符串
读取short类型的值
%hd
读取int类型的值
%d
读取long类型的值
