How to copy characters into string vector - c++11

Question

Attempting to copy from a character vector to a string vector has been unsuccessful across multiple attempts at a solution
allocating memory to the vector prior to copying allows std::copy to work properly when placed at "OutputIterator result" (based on function template). I attempted:
std::copy(char1.begin(), char1.end(), v1.begin());
however, this was unsuccessful as well. using back_inserter returns error c2679 "binary '=': no operator found which takes a right-hand operand of type'char' (or there is no acceptable conversion).
input file is located here: https://adventofcode.com/2018/day/2
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <cstring>
#include <algorithm>
#include <iterator>
#include <cstdio>
int main() {
std::string field1;
std::string field2;
char characters;
std::vector<char>::iterator ptr;
std::vector<char>::iterator ptr2;
std::vector<char> char1;
std::vector<char> char2;
int size = 0;
std::ifstream inFile;
inFile.open("C:\\Users\\Administrator\\Desktop\\c++ files\\input2.txt");
if (!inFile) {
std::cout << "abort";
return 1;
}
while (inFile >> characters) { //read variables from input stream
char1.push_back(characters);
}
std::vector<std::string> v1(6500);
std::copy(char1.begin(), char1.end(), std::back_inserter(v1));
inFile.close();
return 0;
}
//26
expect vector v1 to hold values in vector char1. I am assuming the problem stems from the data type of v1 vs. char1, however, I have not been able to find a concrete solution. I do not want to read directly into a string vector; hence my current problem.

I am not sure what you try to achieve. Here few examples:
#include <string>
#include <vector>
int main()
{
std::string str1{ "Just for an example" }; // You can read it from a file
std::vector<std::string> vct_str1(32); // Lets say it has 32 std::string items
std::vector<std::string> vct_str2(32); // Lets say it has 32 std::string items
// **** A. Copy from std::string to std::vector<char>: ****
std::vector<char> vct_ch(str1.begin(), str1.end()); // On construction
// Or later: vct_ch.assign(str1.begin(), str1.end());
// **** B. Copy from std::vector<char> to std::string: ****
std::string str2(vct_ch.begin(), vct_ch.end()); // On construction
// Or later: str2.assign(vct_ch.begin(), vct_ch.end());
// **** C. Copy from std::vector<char> to std::vector<std::string>: ****
vct_str1[0].assign(vct_ch.begin(), vct_ch.end()); // Which is similar to B
// **** D. Source & Dest Types same as in Case-C But char per std::string: ****
int i = 0;
vct_str2.resize(vct_ch.size());
for (auto item : vct_ch)
vct_str2[i++] = item;
return 0;
}
