例如，要格式化一个浮点数并希望结果保留两位小数，可以设置相应的精度。与width的用法类似，这些参数可以通过在format字符串中指定相应的值来进行设置。specifiers（说明符）用法 specifiers指定变量类型及输出长度。它通过合理使用实现精确控制。specifiers在格式化字符串中是不可或缺的，例如，需要打印百分号（%），只需连...
程序执行到printf函数时,会根据格式字符串中定义的格式,将后续的参数转换为字符串,并输出到屏幕上。 二、FORMAT SPECIFIERS的使用 格式说明符(Format Specifiers)是printf函数中的核心,它们决定了如何将参数转换为可输出的字符串。每个格式说明符都以%符号开始,后面跟着指定参数数据类型和格式的字符。 常见的格式说明符...
