 在 Make 中，`%` 和 `*` 都叫作通配符，但是它们是两个完全不同的东西。`*` 会搜索你的文件系统来匹配文件名。我建议你应该一直使用 `wildcard` 函数来包裹它，要不然你可能会掉入下述的常见陷阱中。真是搞不明白，不用 `wildcard` 包裹的 `*` 除了能给人徒增迷惑，还有什么可取之处。
 
 ```makefile
-# Print out file information about every .c file
+# 打印出每个.c文件的文件信息
 print: $(wildcard *.c)
-    ls -la  $?
+	ls -la  $?
 ```
 
 `*` 可以用在 `targets`、`prerequisites` 以及 `wildcard` 函数中。
