#includeIn this example, the ifstream object is created with the file name "test.txt". Then, the close() method is called on the object to close the input file stream. This will clean up the resources used by ifstream object. The package library used for ifstream and other standard C++ input/output stream classes is#include using namespace std; int main(){ ifstream myFile("test.txt"); //creating an object of ifstream class myFile.close(); //closing the input file stream return 0; }
