Variadic Functions in C Programming | ALX PEER DISCUSSION

In this ALX peer learning discussion, we discussed what variadic functions are and how to use them in writing programs in C language. Here is a list of the things covered in this discussion

* What are variadic functions in C programming
* Why we need variadic functions
* When you will need to use variadic functions
* How to use variadic functions
* Understanding and using the various macros (va_list, va_start, va_args, va_ends)
* Practical examples of usage of variadic functions

I wish I could have a PLD like this. Thank you. This is far better than the Live Learning Sessions

[babalolakehindebenjamin]

really made me understood variadic function to the fullest. Cant thank you enough for your detailed explanations and examples.

[ankitsaurabh_]

You are superb Obed. Keep bringing us lectures like this. Thanks and love from India.

[aduragbemioduntan]

Awesome video.
I wish there is a way to give this video multiple likes.
Thanks for the impact, it's really making a difference.

Great job 👍

[eyethugwacela]

Very detailed and beginner friendly, I recommend this video for anyone battling with variadic functions.

God bless you Doc. Thanks very much for this.
For va_arg macro function taking char as int is because of "default argument promotions" where each argument that is part of the variable list undergoes additional conversion.
Float arguments are converted to double as in "floating point promotion", while bool, char, short and unscoped enumerations are converted to int as in "integer promotion."

This is really clear and very explanatory

[joebosah]

Bravo
Painstakingly explained
Thank you

[khumbizechimsale]

I'm loving the video already after watching for a min

[vodinaefem]

Lovely video, thank you so much for sharing !

[ABUHMOSES]

you did a great job thanks, well done.

[alfredbalazirelurhakongola]

Thank you so much, Dr. I am being made by your kind of explanations. we are kindly requesting your Printf link, it has given us hard time.

[isaacazameti]

Very informative! Keep up the good work.

[phumelelemdlalose]

Thanks for sharing your knowledge sir. But you didn't upload the printf video.😢

[NzewunwaGraceOnyinyechi-sves]

#inlude "printf.h"
int _printf(cons char *format, ...)
{
*format = %d, %s, %c;
va_list my_pritf;
va_start(my_printf, args);
if (*format == %d, %s, %c)
write (1, format, 1, strlen(c), strlen(s))
}

[josiahufono]

In summary macros are like libraries. Right?

[stephan]

Hello. What are the specs of your laptop ?

[solomonpeter]

Please how can I join such a PLD? I'm so much in need of this learning group. Any telegram channel that I can join?
