C/C++ 中,如果需要将 int 或者 unsigned int 以及 long 和 unsigned long 类型数据互转,则可以参考一下代码 #include<cstdio>typedef unsignedintuint32_t; typedef unsignedlongintuint64_t; typedef unsignedcharuint8_t;booltransferLong2ByteArray(uint8_t*byte, uint8_t length, uint64_t version){ uin...
uint64_tisunsigned longon linux and macOS because the typeunsigned longhas 64 bits so there is no need to use a type with a larger rank such asunsigned long longeventhough this later type also has 64 bits. On Windows,uint64_tcannot be typedefed tounsigned longbecaus...
uint32_t: 使用long存储uint32_t。对于超过Integer.MAX_VALUE的值,通过(long)(value & 0xffffffffL...
3. unsigned int:占用四个字节的无符号整数类型,取值范围为到4294967295。4. unsigned long int:占用四个或八个字节的无符号长整数类型(取决于编译器和操作系统),取值范围为到4294967295或到18446744073709551615。此外,在C99标准中还引入了更多的无符号整数类型,如uint8_t、uint16_t、uint32_t、u...
在C语言中,要打印一个"unsigned long"类型的变量,可以使用"%lu"格式化字符串来实现。下面是一个示例代码: 代码语言:c 复制 #include <stdio.h> int main() { unsigned long num = 1234567890; printf("The unsigned long number is: %lu\n", num); return 0; } 在上述代码中,我们定义了一个名为num的...
比unsigned long类型更大的数据类型是unsigned long long,此类型一般用于表示64位的整型变量,在vc开发环境中一般被typedef成__uint64。long long 类型的范围是:-9223372036854775808~9223372036854775807 如果只用正数可以考虑用unsigned long long范围是:0~18446744073709551615 如果需要更大的数字可以考虑使用 ...
But it is printing some random constant value even if i change data. I have used %d , %ld, %lld and %llu for printing but none of those work. So please tell me how to print data of type unsigned long long (uint64_t ) using System_printf() and System_flush() . ...
我也很讨厌这一点,不过这个代码可以改一下,把i>=0改成~i就可以了,这样就无关有符号无符号的问题...
由于数据的长度和平台相关,所以基于 64 位系统比较。 格式控制(printf) 测试代码 #include<cstdio>intmain(){unsignedintui =-1;unsignedlongul =-1;unsignedlonglongull =-1;size_tst =-1;printf("ui=%u,ul=%lu,ull=%llu,st=%zu\n", ui, ul, ull, st);return0; ...
