Certainly! Here’s an alternative approach to accomplish the same task.
In this solution, we will use the fstream library to handle file operations.
Here’s a sample code to perform the task:
1 #include <iostream>
2 #include <fstream>
3 #include <string>
4
5void writeToFile(std::string data) {
6 std::ofstream outfile;
7 outfile.open("sample.txt", std::ios_base::app);
8 if (outfile.is_open()) {
9 outfile << data << std::endl;
10 outfile.close();
11 } else {
12 std::cout << "Unable to open file." << std::endl;
13 }
14}
15
16void readFromFile() {
17 std::ifstream infile;
18 infile.open("sample.txt");
19 if (infile.is_open()) {
20 std::string line;
21 while (getline(infile, line)) {
22 std::cout << line << std::endl;
23 }
24 infile.close();
25 } else {
26 std::cout << "Unable to open file." << std::endl;
27 }
28}
29
30int main() {
31 writeToFile("Hello, World!");
32 writeToFile("Welcome to File Handling.");
33 readFromFile();
34 return 0;
35}In this code, the writeToFile function appends the provided data to the “sample.txt” file. The readFromFile function reads the data from the “sample.txt” file and prints it line by line.
