There is a string

char buff[1024]; //1024 bsize = 3 // зависит от строки

Receives data, add 0 to the end of the line

 // добавление завершающего нуля buff[bsize] = 0;

Translate string to string

 string name = buff; // результат "hi"

There is one more string

 String test = "hi";

The question arises why the result is false? If it should be true

 if(name == test) // Результат false

    @ Ewrei_228 Of course, that’s the point. Print the ASCII character codes in the name and see what you have there too much. for (char x : name) cout << int(x) << endl; - andy.37

Most likely, non-printable characters (of type \n , \r ) fall into the name string. Check the equality of the row sizes ( name.size() == test.size() ) and if they do not match, output the character codes in the name string:

 for (char x : name) cout << int(x) << endl;
