Namaste sir/ma'am

#include "rapidcsv.h"
using namespace std;

int main(int argc, char **argv)
{rapidcsv::Document doc("tm_mat_turtlebot_0_01s.csv",rapidcsv::LabelParams(0, 0),
rapidcsv::SeparatorParams(','));
std::cout << doc.GetCell(1, 0);
std::vector col = doc.GetColumn("Close");
std::cout << "Read " << col.size() << " values." << std::endl;

return 0;

`

I want do read the data of the attached csv file using this code. But I am not able to read it. Can anyone please help me here?

Hi @SANGEERTH-P - there are a couple of issues with the provided code:

• rapidcsv get-methods (GetCell, GetColumn) require specifying which type to get, ex: GetCell<float>(1, 0)
• std::vector also requires a type, ex: std::vector<float>
• when creating the Document instance for a CSV file using commas , as separators and having first row being column labels, you can skip specifying LabelParams / SeparatorParams so the default values are used.

Here's updated code which should work for the provided CSV file:

#include <iostream>
#include <vector>
#include "rapidcsv.h"

int main(int argc, char **argv)
{
  rapidcsv::Document doc("tm_mat_turtlebot_0_01s.csv");
  std::cout << doc.GetCell<float>(1, 0) << std::endl;
  std::vector<float> col = doc.GetColumn<float>("initial_yaw_angle");
  std::cout << "Read " << col.size() << " values." << std::endl;

  return 0;
}
