1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

//C++ program to create a file. #include <iostream> #include <fstream> using namespace std; int main() {    fstream file; //object of fstream class         //opening file "sample.txt" in out(write) mode    file.open("sample.txt",ios::out);         if(!file)    {        cout<<"Error in creating file!!!";        return 0;    }         cout<<"File created successfully.";         //closing the file    file.close();         return 0; }

int main()
{
	char ch;
	const char *fileName="test.txt";
	
	//declare object
	ifstream file;
	
	//open file
	file.open(fileName,ios::in);
	if(!file)
	{
		cout<<"Error in opening file!!!"<<endl;
		return -1; //return from main
	}
	
	//read and print file content
	while (!file.eof()) 
	{
		file >> noskipws >> ch;	//reading from file
		cout << ch;	//printing
	}
	//close the file
	file.close();
	
	return 0;
}
