I keep getting this error:

/tmp/cckjpzdV.o: In function `main': main.cpp:(.text+0xde): undefined reference to `rCopy(std::__cxx11::basic_string, std::allocator > const&, std::__cxx11::basic_string, std::allocator > const&)' collect2: error: ld returned 1 exit status

Help! Thank you!

Write a function called rCopy that copies the entire contents of one file to another, but copies them over in reverse order. This function should take the names of the input and output files as strings. If either file does not open for any reason, the function should output an error message stating the name of the file that didn't open and then return the value false. Otherwise, if both files open correctly, the function should return true once the reverse copy has been completed. For example, if a file named in.dat contains the following: Acd 87 arc 6587 99 then after the function call: rCopy("in.dat", "out.dat") the file out.dat should contain the following: 99 7856 cra 78 d CA You must solve this recursively!! To implement this recursively you will need to write a helper function that passes in an input and an output file stream. This helper function will be the recursive function. Recall that the expression cin.get(ch) will read in a single character from cin into a char variable named ch. main.cpp #include #include using namespace std; void rCopy(istream &, ostream &); bool rCopy(const string &, const string &); int main(int arge, char *argv[]) { if (argc != 3) { cout =0;--i) { for(int j=array[i].size()-1;j>=0;--;) { out
