二、字符串转hex 这个是用于把字符串占两个字节的，合成为一个hex使用。比如:“FF” -> 0xff 字符串占用的是两个字节的数其实是一个hex的，那么就要位移合成。uint16_t stringtohex(uint8_t *buf, uint8_t * format, uint16_t us_length){ uint8_t tempcode;uint16_t uslength =...
1、使用itoa(int to string) //char *itoa( int value, char *string,int radix);// 原型说明:// value:欲转换的数据。// string:目标字符串的地址。// radix:转换后的进制数,可以是10进制、16进制等。// 返回指向string这个字符串的指针intaa=30;charc[8];itoa(aa,c,16);cout<<c<<endl;// 1...
这段代码首先定义了一个hexStringToInt函数,该函数接受一个16进制字符串并尝试将其转换为int。它使用std::istringstream和std::hex来设置读取的基数为16,并使用std::stoul(通过>>运算符隐式调用)来读取无符号长整型值。之后,它检查是否读取了整个字符串(即是否到达eof),并捕获了可能的无效参数异常和溢出异...
1、使⽤strtol（string to long）1 string s = "17";2 char* end;3 int i = static_cast<int>(strtol(s.c_str(),&end,16));4 cout<<i<<endl; // 23 5 6 i = static_cast<int>(strtol(s.c_str(),&end,10));7 cout<<i<<endl; // 17 2、使⽤sscanf 1 int i;2 ...
