静静分析了下,c#工程师是把每个数据转成uint,然后去校验的。于是,费尽九牛二虎之力,将每个数据都转成uint32的整数,实现代码如下(在网上找的) public static long bytes2int(byte[] src){ int firstByte = 0; int secondByte = 0; int thirdByte = 0; int fourthByte = 0; int index = 0; long an...

int16_t 强转为uint16_t int32_t 强转为uint32_t#无符号转有符号如: uint8_t 强转为int8_t uint16_t 强转为int16_t uint32_t 强转为int32_t 举例: int32_t val = -121; uint32_t new = (uint32_t)val; printf("val = 0x%x, %d, new = 0x%x, %d\n", val, val, new, new);...

(7条消息)C字符串与uint32类型互相转换 1.字符串转换为 unsigned int 类型 /*将传入的字符串转换为无符号的的32位整形 *@param: str : 传入的字符串 *retval: The converted value. */ static unsigned int atoui(const char *str); unsigned int atoui(const char *str)...
壹: 经常用到c,积累一些小函数,免得下次还要重新写,极大的提升工作效率啊。 贰: 代码很简单,直接上源码: #include<stdio.h>typedefunsignedcharuint8_t;typedefunsignedintuint32_t;uint32_ttest_val=0x12345678;intmain(){printf("test init value is:0x%x\n\r",test_val);// expected resultuint8_tval1...
typedefunsigned__int32uint32_t 1. 其实就是无符号的32位int型数据。对于编程中出现的“uint32_t没有被定义”的错误,只需要将这行代码加载程序中就可以了 那么问题来了,对于这个类型的变量如何输入与输出呢。。。 下面给个例子(vc6.0) #include<stdio.h> ...
