Files

Open in Code Editor Copy Instructions Submit Solution

A common topic for AS papers and occasionally asked about for IG/O-Level is file handling

Here are some example programs you could try to create

• Read and output a txt file of a story - e.g. Shakespeare
• Copy all lines/the first n lines/last n lines/every other line from one file to a new file
• Copy all lines starting with a certain string to a new file
• Create a program that can encrypt a message and write it to a file - then another module/program to decrypt it
• Create a simple encoding using emojis - e.g. "5R4B" could mean 5 red circles, followed by 4 blue circles. Your program would read this text file and display the image from these coloured circle/square emojis
• Count number of lines/characters/words/paragraphs in a file
• Output a specific/range of lines from a file based on the line numbers
• Read a file and display the line number alongside each line
• Remove empty lines from a file
• Parse a .csv file (can ignore commas enclosed within quotes - keep it simple if you want)
• Sort the lines of a file alphabetically
• Merge multiple files into a single file
• Create a custom encoding which you can write/read from a file
• Split large files into multiple smaller ones - e.g. max of 10 lines
• Create a login program - log successful/unsuccessful attempts to a file along with the date/time - could be used by system admit to detect brute force login attempts
• Create a menu that allows the user to enter a filename, then read/write/append to it

...etc - there are many different examples you can think of

As a target, let's try and have 10 programs submitted by members of the community for others to enjoy...good luck...and have fun!
