The total number of bytes that may be passed to this function is limited due to the memory restrictions imposed by the 8051. A maximum of 15 bytes may be passed in SMALL or COMPACT model. A maximum of 40 bytes may be passed in LARGE model. Return Value Theprintffunction returns the num...
whereas printf only checks if the format string is a null pointer. If either check fails, an invalid parameter handler is invoked, as described inParameter Validation. If execution is allowed to continue, the function returns -1 and sets errno to EINVAL. ...

Specifies a no-op character. An optional decimal digit string that specifies the minimum field width. If the converted value has fewer characters than the field width, the field is padded on the left to the length specified by the field width. If the-(left-justify) o...
printf("It is other character\n"); } 第1空:字符在计算机中以ASCII码的形式存储。所以当输入的字符,即ch中字符所对应的ASCII码的范围在英文字母的ASCII码的范围内即可,参照p377。由于英文字母又分为大写字母和小写字母,因此此处用一个逻辑或表达式,表示ch中是小写字母或者大写字母,都能使得表达式成立。ch>=97...
printf(“you input is 1\n”); } else printf(“you input is another\n”); 上面的代码表示,如果num=1,输出you input is 1。如果不是,输出you input is another。 这是最基本的选择语句。if或者else条件后面只有一条语句时,花括号可写可不写,不加的话记得缩进,为了美观和规范,一般写上。

There is a known issue in the UCRT that is currently maintained for compatibility. Like theSspecifier, theZspecifier without a size modifier prefix refers to aUNICODE_STRINGwhen using a narrow printing function (likeprintf) and anANSI_STRINGwhen using a wide printing function (likewprintf)...
