Hi there,
I'm coding a program in C++ whose purpose is data logging, in it i'm using GNU radio libraries. In addition, i'm declaring gr hierarchical blocks in the code as they have a connect function that simplifies the complexity of the program.
I'm using Visual studio IDE with visual C compiler to run the program and as i do i get various errors which i have been trying to figure out for days. I've googled similar errors and asked in stackoverflow but i've had no luck.
Ill include some of the lines of errors i'm getting as well as some lines of code(the program is small) to make this email as clear as possible. In the attachment i included a txt file that contains the full code and errors.

......
As for attempted solutions i included the complex and xlocnum but had no luck.
Another posible solution was that std:: is said to be undefined behaviour, so i added "using namespace std;"(which is suggested not to do but how else would i declare the strings and vector<float>) and deleted the "std::" in each line that contained it, but again no luck.
If anything is required of me do not hesitate to ask, any sort of help is greatly appreciated.
Ill include the headers im using here also:
#include <iostream>
#include "stdafx.h"
#include <cmath>
#include <uhd/usrp_source.h>
#include <filter/firdes.h>
#include <gnuradio/filter/fir_filter_ccf.h>
#include <gnuradio/top_block.h>
#include <gnuradio/blocks/head.h>
#include <gnuradio/blocks/skiphead.h>
#include <gnuradio/blocks/complex_to_float.h>
#include <gnuradio/blocks/float_to_complex.h>
#include <gnuradio/blocks/interleave.h>
#include <gnuradio/blocks/file_meta_sink.h>
