Writing to text files in C

Hi. fopen and sprintf have different parameters now (2 in fopen and 2 + n for sprintf). Did that change over the course or am I missing something?

Where can I learn more about why FILE is used, or the difference between any of these functions and their differences between them and their _s counterparts, or why a buffer is needed.

hi, im new to reading and writing files, may i know why you declared two char strings buffer_in and buffer_out and only used buffer_out ?

All great!
Only one question, you are using fwrite function which means you are saving your data in binary right? I guess your editor just lets you see the .dat file in text format

Is there a way to get ready/write capabilities on the same file at the same time? Is that best practice?

You are very impressive with your videos..

I get a warning "passing argument # of 'sprintf' makes pointer from integer without a cast".

thank you so much, really

Nice informative video, keep up the good work!

hi , just a quick note that when you clarify the struct type again at the end the clarification at the beginning is optional,
so you can write it like:
typedef struct{
}point;

Are u portugues?

Awesome video. Custom-formatting data with sprintf_s() before writing it to a text file is very useful. Thank you for taking the time to make this content and explain it so very well.

Question, should you write strlen(buffer_out) + 1 to include \0 in general or does it not matter?

Clear and objective explanation... I'm in love with yours videos, sir

what is difference between fpritnf and sprintf ?

You can use,
# pragma warning(disable:4996)
at the start of your file it disables warnings related to _s or secure functions in Newer versions of Visual Studio.

Thank's for these videos, how can i set the txt file in utf8 for characters like "ñ"

fprintf is also a convenient function to use, right?

thanks for the video man!
