C++ program to create a file
Problem Statement: Write a C++ program to create a file using file handling and check whether the file is created successfully or not. If a file is created successfully then it should print “File Created Successfully” otherwise should print some error message.
Approach: Declare a stream class file and open that text file in writing mode. If the file is not present then it creates a new text file. Now check if the file does not exist or not created then return false otherwise return true.
Below is the program to create a file:
// C++ implementation to create a file#include <bits/stdc++.h>using namespace std; // Driver codeint main(){ // fstream is Stream class to both // read and write from/to files. // file is object of fstream class fstream file; // opening file "Gfg.txt" // in out(write) mode // ios::out Open for output operations. file.open("Gfg.txt",ios::out); // If no file is created, then // show the error message. if(!file) { cout<<"Error in creating file!!!"; return 0; } cout<<"File created successfully."; // closing the file. // The reason you need to call close() // at the end of the loop is that trying // to open a new file without closing the // first file will fail. file.close(); return 0;} |
