Write a Program to open close a file in c?

Answer 1

You have to use the preprocessor directive fstream.h.

#include <fstream.h>

void main ()

{

ifstream inDataStream;//the stream to open excess to a file

inDataStrea.opem("fileName.txt");//to open an excess to the file fileName.txt (can be //any)

if (inDataStream.fail())//check if the file was opened successfully

{

cout << "Couldn't open the file!";

}

inDataStream << "Hello";// writing the word "Hello" in the file (can be any information)

inDataStream.close();//close the opened excess to the file

}
