Using qsort() To Sort An Array | C Programming Example

Other relevant videos to help understand what's happening with the comparison function...

The compare function is so well explained.

I still dont get how qsort works with the x and y, does it iterate in the loop assigning a digit x and its successor y?

[idkzsh]

you explained this so much better than my prof. prof puts me to sleep.

So basically, if I understood correctly, the 4th argument of qsort is a function pointer returning an int, which is very interesting if this is the case. Function pointers are powerful and I would like to know more about their use in practice. Thank you.

thank you, a clear, easy to understand tutorial!

does the compare function has to take const void pointer as parameters? or could it also take another type like const int pointer, so we don't need to use pointer magic and keep the code a bit more simple?

thanks from russia, first video about comparator that i found

[akshatkhatri]

great video
so if we want to use it with array of structures instead of integer array; how exaclty will the casting be done i m a bit confused

[philipphortnagl]

I don't get how the compare function works without giving any arguments. I mean you say, we assume the numbers "2" and "5" from the array, but how is this actually working in the function without explicitly giving any arguments for the function?

[kianoushmehrandish]

have you created a same video for sorting structs?

[nguyentuan-efhr]

Hmm why when you read the array and call qsort you can know is 2-7 but not 7-2 ur because you read the array from a[0] not form the last p/s : sorry if my english is bad

i am trying to sort ' ' ' float array[5]= {11.1f, 11.34f, 11.22f, 11.99f, 11.00f}; ' ' ' it won't work in qsort why? any solution if i want to sort float using qsort?
