This was done in C program using visual studios, my codes works, but it doesn't do what I need it to do, please keep my same code, and edit it to give me what I have written down.

I provided all my source files and header files , I am not sure if it's a problem with my main function or one of the source files as well, please also give me the code and a brief step on how to enter in the database(maybe I'm entering it wrong )

I want my code output to be like the picture I written out. Not like the last picture, I am making a database project that should allow me to make multiple entries, be able to save it to a disk file, be able to read it from the disk and display it, My problem is, it always override the data I previously entered, if I type "55555" then "44444" it deletes the "5555" instead of adding "4444" to the other line Can someone suggest what code I am missing and where to place it, to have my output the way I have it written on the piece of paper
