error: no matching function for call to ‘std::vector

Question

I write func to write strings from file to vector and have a error

error : error: no matching function for call to ‘std::vector<std::__cxx11::basic_string<char> >::push_back(std::ifstream&)

code:

//parse file file

#include <fstream>
#include <vector>

const unsigned short numOfStrings=5;

void ReadFromFile (std::ifstream& thisin, std::vector<std::string>& thisData)
{
    thisData.push_back(thisin);
}

int main ()
{
}

You forgot to add a while loop in you function that reads in the strings from `thisin` and then you can add those strings into the vector. — NathanOliver, Aug 31 '21 at 14:19
See part 2 of this answer: [https://stackoverflow.com/a/7868998/487892](https://stackoverflow.com/a/7868998/487892) on how to read a file line by line. You don't need the inner `std::istringstream iss(line); ...` part replace it with `thisData.push_back(line);` — drescherjm, Aug 31 '21 at 14:23

You are trying to push into the vector the ifstream, not reading from it.

To read from ifstream, you could have done the following.

void ReadFromFile (std::ifstream& thisin, std::vector<std::string>& thisData)
{
    std::string word;
    while(thisin >> word)
    {
        thisData.push_back(word);
    } 
}
