In order to write data to a spreadsheet in C++, you can follow these steps:

1. Include the necessary header files: #include <iostream> and #include <fstream>.

2. Define a function writeDataToSpreadsheet that takes the filename of the spreadsheet and the data to be written as input.

1void writeDataToSpreadsheet(const std::string& filename, const std::vector<std::vector<std::string>>& data) {
2    // Code to write data
3}

3. Inside the writeDataToSpreadsheet function, open the spreadsheet file using an ofstream object.

1std::ofstream file(filename);

4. Check if the file was successfully opened, and handle the error if it fails.

1if (!file.is_open()) {
2    std::cout << "Failed to open file" << std::endl;
3    return;
4}

5. Iterate over the data vector, which contains the rows of the spreadsheet.

1for (const auto& row : data) {
2    // Code to write row
3}

6. Inside the row loop, iterate over the cells of each row and write them to the file separated by commas.

1for (const auto& cell : row) {
2    file << cell << ",";
3}
4file << std::endl;

7. Close the spreadsheet file.

1file.close();

8. In the main function or wherever you want to use the writeDataToSpreadsheet function, provide the filename and data to be written.

1std::vector<std::vector<std::string>> data = { {"John", "Doe", "john.doe@example.com"}, {"Jane", "Smith", "jane.smith@example.com"} };
2std::string filename = "data.csv";
3
4writeDataToSpreadsheet(filename, data);

9. Finally, compile and run the program. The data will be written to the specified spreadsheet file.

1int main() {
2    // Code to call writeDataToSpreadsheet
3    return 0;
4}

By following these steps, you will be able to write data to a spreadsheet in C++. It's important to ensure that the file is successfully opened before writing, and handle any errors that may occur.
