在c++中将const vector<uint8_t>强制转换为const vector<char> c ++从LPCTSTR转换为const char* 允许为std :: string分配"const char*",但是不能编译分配给std :: wstring.为什么? 将std::string转换为const char *和函数调用 C++样式从unsigned char*转换为const char* ...

response[i] = packet_get_string(NULL); } 上面这个代码中,nresp是size_t类型(size_t一般就是unsigned int/long int),这个示例是一个解数据包的示例。一般来说,数据包中都会有一个len,然后后面是data。 如果我们精心准备一个len,比如:1073741825(在32位系统上,指针占4个字节,unsigned int的最大值是0xffff...
