+1. 定义`int num = 255`，分别以十进制（有符号）、无符号十进制、八进制（带 / 不带前缀）、十六进制（小写带 / 不带前缀、大写带 / 不带前缀） 格式输出；
+2. 定义`long num_long = 123456789`、`long long num_ll = 9876543210`，分别用对应控制符输出；
+3. 定义`float pi = 3.1415926`，分别以默认小数形式、保留 2 位小数、指数形式（保留 3 位精度） 输出；
+4. 定义字符串`char *name = "Programmer"`，分别输出完整字符串、前 5 个字符、左对齐占 10 位、右对齐占 10 位的格式；
+5. 编写一个综合程序，结合格式化输入输出、类型转换、IO 流知识点，实现 “字符↔ASCII 码” 双向转换：
+	1. 提示用户选择功能：输入 1（字符转 ASCII）、2（ASCII 转字符）；
+	2. 若选择 1：接收用户输入的单个字符（注意：需处理 scanf 接收字符时的缓冲区问题），输出该字符的 ASCII 码（结合类型转换，char→int）；
+	3. 若选择 2：接收用户输入的 ASCII 码值（0-127），输出对应的字符（int→char，显式转换）；
+	4. 增加输入校验：若输入的 ASCII 码超出 0-127 范围，输出 “无效的 ASCII 码”；若输入的不是单个字符，输出 “输入格式错误”；
+	5. 核心要求：使用scanf的返回值判断输入是否有效，结合格式化控制符完成输入输出
