#includeIn this example, we create an ifstream object called 'infile' and open the file "example.txt". We then check if the file can be opened using an if statement. We then create a string variable 'line', which we use to store each line of the file as we read it in a while loop using getline. The while loop outputs each line to the console until there are no more lines left to read. Finally, we close the file using infile.close(). Overall, ifstream getline is a useful function for reading text and other data from files in C++ programs.#include #include using namespace std; int main() { ifstream infile; // create input filestream object infile.open("example.txt"); // open the file if (!infile) { // check if the file can be opened cout << "Error opening file." << endl; return 1; } string line; while (getline(infile, line)) { // read each line in the file cout << line << endl; // output the line to console } infile.close(); // close the file return 0; }
