另外printf函数输出64位数的问题,其实在window下和linux下是不一样的: linux下是 printf("%lld/n",a); printf("%llu/n",a); windows下是 printf("%I64d/n",a); printf("%I64u/n",a); #include<stdio.h>#include<stdlib.h>typedefunsignedlonglongint64;typedefunsignedlonglonguint64;longlongx=62232...
从函数声明我们可以看出转换函数仅支持到32位数据,如何实现64位数据的转换呢? 下面给出我们自己的实现方法: uint64_tntohll(uint64_t_netlong){uint64_tresult=ntohl(_netlong);return(result<<32|ntohl(_netlong>>32));}uint64_thtonll(uint64_t_hostlong){uint64_tresult=htonl(_hostlong);return(resul...
C语言中的长整型指的是比整数更大范围的数值类型,其常见的格式包括有符号长整型int64_t和无符号长整型uint64_t。与其他类型一样,长整型需要先输入才能进行后续的操作。下面我们将分步骤阐述C语言长整型的输入格式。 1.使用scanf函数输入长整型数值 首先,我们可以使用C语言中的scanf函数来输入长整型数值,其使用方法...
