I have a
std::vector<unsigned char> data;
which contains a binary read file.
If I write it to
std::ofstream outputFile("file", std::ios_base::binary);
I'll see a regular text in it. Then I can read it into std::string which will conatain the text. Is it possible to copy vector directly to string with the same result?
Use the 6th form of std::string's constructor:
// Example program
#include <iostream>
#include <string>
#include <vector>
int main()
{
std::vector<unsigned char> data{'a', 'b', 'c'};
std::string str(data.begin(), data.end());
std::cout << str << std::endl;
}
From http://www.cplusplus.com/reference/string/string/string/.
Use std::String s(data.begin(), data.end());.
std::string s(data.begin(), data.end());Or if you already have a string:s.assign(data.begin(), data.end());
