In the end, we are closing the file through outfile.close() method. After opening this file we are writing some text into the file. The through outfile.open we are opening a file name ” Demo.txt”. As we are using ostream to handle the output stream. Here is another C code to demonstrate the working of the stream for writing into a file in programming.Įxplanation: As you can see in the above code we have used fstream in our header files to include all the file and iostream classes. By using getline() we are reading every character then writing it into the demo.txt file. As the texts are character therefore, we have to declare the string line character so that we can read all the texts from the file. In the end, we are closing the file through a file.close() method. open we are opening a file name ” Demo.txt”. As we are using Ustream to handle the output stream. While ( getline ( personal_filein, line ) )Įxplanation: As you can see in the above code we have used fstream in our header files to include all the file and stream classes. Personal_filein.open ("Demo.txt") // connecting personal_filein to file Input File Ifstreampersonal_filein // here the personal_filein is an input stream Personal_file.close () // closing the output file stream Personal_file<< "Start learning file handling.\n" Personal_file<< "HEY! Welcome to C File handling.\n" Personal_file.open("Demo.txt") // connect outs to file outFile Ofstreampersonal_file // outs is an output stream of iostream class Here is the C code to demonstrate the working of ifstream classes: Finally, we closed the file after writing the information into it. Personal_file<< " Writing this to a file.\n " Įxplanation: In the above code, we are creating a file with the name file and then we are creating an ofstream object so that we can write into the file after opening it through the file. Here is the C code to demonstrate the working of the stream for writing into a file in programming. This ios prefix is used to treat the given file as a binary format. This ios prefix is used to open a file and append it to the end. This ios prefix is used to truncate the existing file. This ios prefix is used to open a file without truncating and allows data to be written anywhere in the mentioned file. This ios prefix is used to open a file to write the output from the user. This ios prefix is used to open a file to read input from the user. But before moving to the code we will see the different types of file modes can be used in our source code through the below table: Input-Output Stream Prefix Different Types of File ModesĪs we have seen what ifstream is and how can we use it in our code for performing various operations in code, it can be reading a file, writing to a file or maybe accessing a file, In addition, we will see the working of ifstream through some C code examples. Ifstream object is used for reading the file ofstream object is used to write the file in your code. Now let us have a look at the syntax of ifstream classes: ifstreamobject_name( "file_name " )
