After this lesson you will know what you will learn in this course.

Preview 03:26

What is stream, input and output. We are making ourselves familiar with word stream, input and output.

+ File Stream Library (fstream)
12 lectures 01:50:52

Your learn how to close and open files and how to check if the filed was opened properly. You also learn how to simply put text into file.

Preview 06:27

You learn file opening modes (states) and differences between them. We learn how to open file and:

  1. make it readable
  2. make it writeable
  3. being able to add content to it
  4. treat it as binary file (we also learn difference between binary and text file)
  5. keep the content / truncate content after opening
File opening modes
13:24

We discuss all stream's error flags and we show how to use them. You will know how to react on unexpected situations that happens during reading from the file like for example assigning string to integer or opening file for writing which had the flag set to only reading (ios::in)

You will know functions like:

  1. fail
  2. good
  3. bad
  4. eof
  5. clear
  6. rdstate

and you will know how to operate on states (failbit, goodbit, badbit, eofbit) using bitwise operators and rdstate function.

You will know how to read whole file using one loop and eof function.

Stream's error flags
17:41

What are and how to use reading position pointer. How to programitically check how many bytes the file has. You will learn and understand functions that reads and sets position of reading pointer.

Reading position pointer - seekg and tellg
08:53

You will know what is and how to use writing position pointer. You will learn functions seekp and tellp which allows you to retrieve and show where is the writing pointer.

Writing position pointer - seekp and tellp
03:56

You will learn:

  1. how function getline and ignore works
  2. how to retrieve all lines of text from file at once
  3. how to ignore characters that are not needed
  4. how to extract from file with names and surnames only initials
Extracting characters from files
15:26

You will know how read function works. We are creating function that is counting size of file and function that is checking if two binary files are the same. We are training pointers on practical example. We also learn abot memcmp function which is used to compare memory.

Comparing content of two files
25:11

You will learn hot to load characters from standard input (cin) and put them into the file. In addition to this you will learn how to add after each letter of string a space or any other character.

Put - loading characters from cin stream directly to file
04:17

You will learn function that allows to peek characters before exracting and you will know how to retrieve information from steam in order to assign variables to the right type of variables.

Peek - peeking characters without extracting
03:42

You learn how to return extracted character back on the stream so it can be read again

Putback - returning extracted character on stream
02:38

You will learn how to save bytes to files and when you should use write function over saving operator (<<)

Write - writing bytes to file
05:42

You will learn how to get count of characters retrieved from file on practical example.

Gcount - counting characters from last operation
03:35
