I'm new in C language (my 6th day learning C), and this is my 2nd question in here, so I'm trying to save the inputed data from my program to a .csv file using command fwrite below (see the code). But when i opened the csv file, my data only saved to the first cell and its kinda repetitive ( You can see it in the pic below ).
I'm trying to each data to be saved into one cell Like this :

How can i do it? Thanks For your help :3
