Question

I have a string which i then want to store in a vector

string a = "N\nT\n";

after each new line to be in a different cell.

std::string ss (".V/\n.F/\n.R/\n");

for(int i = 0; i< ss.size(); i++)
{
    test1.push_back(ss);
}

I want to store the string in vector test1
is this the best way?

Answer 1

Your code won’t work; it’ll store the string ss.size() times in the vector.

You might want to use a string stream to split the string:

std::stringstream stream(ss);
std::string line;
while (std::getline(stream, line)) {
  test1.push_back(line);
}

Note that the newline character will be discarded. If you want to keep it, push_back(line + "\n");.
