将stdbool.h添加到源文件时，可以使用bool作为类型名称。stdbool.h将符号true和false定义为分别对应于1和0。当转换为bool类型时，非零数值将导致1(true)，0将转换为0(false)。如果在源文件中包含标头，则可以按如下方

_bool类型存储布尔值。布尔值通常来自比较，其中结果可能为true或false。_bool类型的值可以是0或1，分别对应布尔值false和true。

浮点值的格式说明符的一般形式如下：%[width][.precision][modifier]f方括号代表可选规范。可以省略width或.precision或modifier或这些的任意组合。width值是一个整数，指定包含空格的字符总数。precision值是一个
