C++ Convert Hex String Representation to Hex


By : German Gluhhov
Date : September 23 2020, 03:00 AM
fixed the issue. Will look into that further A simple (and slightly naive) way is to get two characters at a time from the input string, put in another string that you then pass to std::stoi (or std::strtoul if you don't have std::stoi) to convert to an integer that you can then put into a byte array.
For example something like this:
code :
std::vector<uint8_t> bytes;  // The output "array" of bytes
std::string input = "f1f2f4f4";  // The input string

for (size_t i = 0; i < input.length(); i += 2)  // +2 because we get two characters at a time
{
    std::string byte_string(&input[i], 2);  // Construct temporary string for
                                            // the next two character from the input

    int byte_value = std::stoi(byte_string, nullptr, 16);  // Base 16
    bytes.push_back(byte_value);  // Add to the byte "array"
}

Best way to convert Dictionary<string, string> into single aggregate String representation?

help you fix your problem How would I convert a dictionary of key value pairs into a single string? Can you do this using LINQ aggregates? I've seen examples on doing this using a list of strings, but not a dictionary. , This is the most concise way I can think of:
code :
var result = string.Join(", ", map.Select(m => m.Key + ":" + m.Value).ToArray());
var result = string.Join(", ", map.Select(m => m.Key + ":" + m.Value));
var result = string.Join(", ", map.Select(m => $"{m.Key}:{m.Value}"));
var result = map.Aggregate(new StringBuilder(),
    (a, b) => a.Append(", ").Append(b.Key).Append(":").Append(b.Value),
    (a) => a.Remove(0, 2).ToString());
var map = result.Split(',')
    .Select(p => p.Trim().Split(':'))
    .ToDictionary(p => p[0], p => p[1]);

around this issue hello guys simple question that i seemed to be stumped on. I have something that seems to work but i get a blank result. I have a text string in a column in a database. for the sake of this question lets say the text string is "jhonSmith" I would like to get the hexadecimal representation of this string. using a sql server simple select statement. I do not have access to create or call procedures on the database. this is the best ive been able to come up with but it returns blank. If i take the convert function off then it works. , When I run the following
code :
select distinct convert (varbinary, 'Hogan') as Employee
Employee

hop of those help? I haven't been able to find an answer to the following question: Start with a string, convert it to its binary representation. How do you get back the original string in Python? , use this code:
code :
import binascii
n = int('0110100001101001001000000111010101110011', 2)
binascii.unhexlify('%x' % n)
