例如,下面的C代码将以带前缀的十六进制格式打印一个整数变量: #include<stdio.h>intmain(){intnum=255;printf("0x%x\n",num);return0;} 输出将是: 0xff 打印指针的十六进制表示 在C编程语言中,指针是存储内存地址的变量。通常情况下,我们将指针以十六进制格式打印出来以便于调试和查看内存地址。
c 是 char 型 或 int 型, 或 unsigned char, unsigned int 型 c -- 按对应的 ASCII 字符 输出 x -- 输出它的 16 进制 码 int a=65;printf("%c->hex %x\n",a,a);输出：A->hex 41
冒号没有特殊意思，就是照样打印冒号，于是打印出 c:dec=十进制值 oct=八进制值 hex=十六进制值 。。。
/* UNICODE big 1 */ printf("%lc %ls\n\n",wc,ws); /* The output of this printf is not shown below and it */ /* will differ depending on the device you display it on,*/ /* but if you looked at the string in hex it would look */ /* like this: 0E42F10F404040400E42C142...

令我感到惊讶的是,这个问题中的每个人都声称这种情况std::cout要好得多printf,即使这个问题只是要求差异.现在,有一个区别 - std::cout是C++,而且printf是C(但是,你可以在C++中使用它,就像C中几乎所有其他东西一样).现在,我会在这里说实话; 双方printf并std::cout有自己的优势. 真正的差异 可扩展性 std::cou...

In all cases, nanoprintf will return the number of bytes that would have been written to the buffer, had there been enough room. This value does not account for the null-terminator byte, in accordance with the C Standard. Thread Safety nanoprintf uses only stack memory and no concurrency ...
