Let's test your knowledge. Fill in the missing part by typing it in.
To read data from a spreadsheet in C++, you can use the ifstream class from the <fstream> library. This class provides methods to open and read files. Here's an example:
TEXT/X-C++SRC
1#include <iostream>
2#include <fstream>
3
4using namespace std;
5
6int main() {
7 // Read data from spreadsheet
8 ifstream file("_______________");
9
10 // Check if the file is open
11 if (file.is_open()) {
12 string line;
13
14 // Read each line in the file
15 while (getline(file, line)) {
16 cout << line << endl;
17 }
18
19 // Close the file
20 file.close();
21 } else {
22 cout << "Error opening file" << endl;
23 }
