Is there any way to trick C into accepting default function arguments / optional function arguments? Or do I have to use C++ for that?

Anonymous

I think thats only there for C++

V01D

Okay, thanks.

C doesn't mangle function names

Vlad

You may create a helper function with optional parameters declared as pointers

Vlad

And if a parameter is NULL call function with the default that you wish

Vlad

But you still have to put these NULLs in the call

V01D

So if I didn't put NULL in the function call I would get a compiler error, right?

Exactly, because number of parameters doesn't match

void func(char* str, void* anything) { // do stuff } int main() { func(NULL, NULL); } This is what I got from your explanation.

Vlad

But I would do just a name convention for that. If you don't have too many optional parameters

void func_(int a, float b) { } void func(int* a, float* b) { int aa = a ? *a : 12; // 12 is default float bb = b ? *b : 0.0f; func_(aa, bb); } int main() { func(NULL, NULL); }

THis is a brand new install, Still getting this damn error

void func_(int a, float b) { } void func(int* a, float* b) { int aa = a ? *a : 12; // 12 is default float bb = b ? *b : 0.0f; func_(aa, bb); } int main() { func(NULL, NULL); }

Oh, okay. Thanks

Any ideas?

Pavel

Any ideas?

The error says that windows sdk is not found, I would start from installing (reinstalling) it. Not sure why it needs it for a console application though.

Vlad

Any ideas?

Try setting existing one in the project settings

Vlad

Chances are they just different versions

But it needs this version.....

Vlad

Get into this menu and change it

Vlad

On the sdk version that's installed on your pc

Vlad

Yeah ms products still are very convenient

i prefer vs code

Vlad

Your .exe could be open

Vlad

If so close it and try again

Bala

Your .exe could be open

Where should open that

Vlad

Where should open that

ctrl + alt + del and check for your exe name in the processes list

Vlad

If it's running compiler cannot override it's file

Why is that not working?

C++ is like a high level version of C

What is difference between C and C++

C was built back when a language had a specific use case unlike python which does everything. You can do ALOT with C, however it was built to develop kernels, compilers, etc. C++ kind of bridges that gap. Note that C++ is OOP, where as C is ROP.

C is a mess and C++ is even bigger mess

guys, I have a code that generates 4 arrays, two with matches and two that point to matches, to run in 1 repetition, it works smoothly, but when I perform 2 or more repetitions, in each repetition it adds positions in the array in place to simply update the values

Perfect, great code. Especially I like a,b,c,d,e,f but g is missing. why?

Vlad

Always wondered why in C where it's the most important to name things convenient way some people go for alphabetical variables instead?

I use g in the main and I don't like to repeat variables

in my case, there are so many for and whiles that alphabetically it was enough

It was sarcastic indeed. Please upload this code on one of the providers and let us investigate whats wrong. It is also missing, whats your problem with this code?

I realized, but as I need help, I have to provide as much information as possible I will generate a pasterbin and the output to be able to clarify the error. basically the offsetZero.coincidences array can only have the predefined size, however when there is repetition, it adds values.

So, please divide your code into functions. Nobody will read your code until it can be readable.

If I use two nested for loop let's say 'i' and inside 'i' use 'j' and inside 'j' if I use another while loop then will the time complexity be O(n^2) or O(n^3)??
