The first optional field in a conversion specification containsflag directives, zero or more flag characters that specify output justification and control output of signs, blanks, leading zeros, decimal points, and octal and hexadecimal prefixes. More than one flag directive may appear in a conversion...

从函数返回一个uint8_t并在main函数中打印它 的问题涉及到函数返回值和数据类型的使用。 首先,函数返回一个uint8_t表示该函数返回一个8位无符号整数。在C语言中,可以使用关键字uint8_t来定义一个8位无符号整数类型。 下面是一个示例代码,展示了如何从函数返回一个uint8_t并在main函数中打印它: 代...
blanks are added to the left or the right of the values—depending on whether the left-alignment flag (-) is specified—until the minimum width is reached. Ifwidthis prefixed by 0, leading zeros are added to integer or floating-point conversions until the minimum width is reached, except ...
