Hello! I am unsure of how to do this task. I have to write a program in C++ that creates a file and writes data into that file column wise. The problem is that there is some data that I want to keep there permantely and I do not want to replace it every time. For example this format: TIME DAY MONTH YEAR 01:25 07 JUNE 2008 14:00 30 MARCH 2015 I have (TIME/ DAY/ MOTH/ YEAR) and I want to write that first and that any data that I add later is written under that and so on.

To create a file in C++, you can use the fstream library which provides classes for file input and output operations. To write data column-wise to the file, you can use the setw() function from the iomanip library to set the width of each field.
To avoid overwriting data, you can check if the file already exists and only write the new data. You can also use a database instead of a file to store your data, which will allow you to update and query the data more easily.
Code is given below.
