| As we have already been using in the previous chapters, the format specifier $(STRING " %s") reads the data according to the type of the variable. For example, as the type of the following variable is $(C double), the characters at the input would be read as floating point number: | ||
| $(STRING “%s”) 将根据变量的类型读取数据，这和我们在前一章中使用的相同。比如下面这个类型为 $(C double) 的变量会令程序从标准输入读取浮点型的数据： |

$(STRING “%s”) => $(STRING " %s")

| $(LI $(B The space character): Indicates $(I zero) or more whitespace characters at the input and specifies that all of those characters should be read and ignored.) | ||
| $(LI $(B 空白字符)：说明符或输入中的$(I 零)或多个空白字符将被读取并忽略。) |

错译，应译为：
表示输入中的$(I 零个)或多个空白字符，并指示这些字符应被读取并忽略。

| Reading a single line of data from the input has been recommended as $(C strip(readln())) in the $(LINK2 /ders/d.en/strings.html, Strings chapter). Instead of that method, a $(C \n) character at the end of the format string can achieve a similar goal: | ||
| 在 $(LINK2 /ders/d.cn/strings.html, Strings) 一章中，我们曾推荐使用 $(C strip(readln())) 来按行读取输入的数据。除了这种方法，在格式化字符串后添加 $(C \n) 也可以达到同样的目的： |
| write("First name: "); | ||
| string firstName; | ||
| readf(" %s\n", &firstName); // ← \n at the end | ||
| readf(" %s\n", &firstName); // ← 在末尾添加一个 \n |

此处是输入数据，没有添加意，应译为：
末尾的 \n
与下文（95）呼应
| write("Last name : "); | ||
| string lastName; | ||
| readf(" %s\n", &lastName); // ← \n at the end | ||
| readf(" %s\n", &lastName); // ← 在末尾添加一个 \n |
