Wht does void do?

universal pointer smells like polymorphism in c

Hello

How can we pass one parameter in main for a function having two parameters and still expect the code to work fine.

How can we pass one parameter in main for a function having two parameters and still expect the code to work fine.

Eg- void sum (int a,int b, int c) For sum of three numbers and doing sum of just two numbers in main

I hope my question is clear

Eg- void sum (int a,int b, int c) For sum of three numbers and doing sum of just two numbers in main

You want to do: sum(1, 2); ?

This is an example to make you understand what I'm trying to ask

Eg- void sum (int a,int b, int c) For sum of three numbers and doing sum of just two numbers in main

The Question is different, I want to know the concepts

Eg- void sum (int a,int b, int c) For sum of three numbers and doing sum of just two numbers in main

do you want to return ‘int c’ as a value? do you want to set a default value to ‘int c’ ? I don’t get it

or you want to call a function with only two parameters?

do you want to return ‘int c’ as a value? do you want to set a default value to ‘int c’ ? I don’t get it

Function- Void sum(int a,int b,int c) In main- See If User Want to do sum of 2 Number(passed as argument) the function will work for 2 numbers. If user want to do sum of 3 Numbers(passed as argument) function will work for 3 number

ohh

I hope you understand what I'm asking I can't explain in more detail

😅

yeah, use a pointer void sum(int a, int b, int* c = NULL) { return a + b + (c != NULL ? *c : 0) }

I don’t know if this is valid for older versions of C

yeah, use a pointer void sum(int a, int b, int* c = NULL) { return a + b + (c != NULL ? *c : 0) }

Fuck this bad

Fuck this bad

still better than modern c++

😌

I don’t know if this is valid for older versions of C

It's not valid in ANY version of C

well you got the point

use pointers

Don't do

Don't do

Ok Then what else?

do functions sum2, sum3, sum4 etc

do functions sum2, sum3, sum4 etc

it looks like ultra retarded

sum5, sum6, sum8

just pass an array as parameter LOL (jk)

just pass an array as parameter LOL (jk)

Interesting but C is bad

yeah, use a pointer void sum(int a, int b, int* c = NULL) { return a + b + (c != NULL ? *c : 0) }

I'll go with this

do functions sum2, sum3, sum4 etc

what if he has variable input parameter count

Thanks @Neko_cpp

what if he has variable input parameter count

Suffer

kinda true

And use dynamically allocated arrays

Or VLA since it's C😜

Eg- void sum (int a,int b, int c) For sum of three numbers and doing sum of just two numbers in main

https://en.cppreference.com/w/c/variadic

Eg- void sum (int a,int b, int c) For sum of three numbers and doing sum of just two numbers in main

this is how functions like printf() and scanf() work (not exactly, but almost)

https://en.cppreference.com/w/c/variadic

holy crap I didn’t even think of that

nice

nice

no

nonononono. these are not nice

I mean I’ve totally forgotten about this feature

Eg- void sum (int a,int b, int c) For sum of three numbers and doing sum of just two numbers in main

just in case the nonononos weren't clear enough, don't use them. there is type safety, and then there is the exact opposite ....

I have some question about C

Can i send the code here?

Can i send the code here?

If it’s long enough use pastebin or something

Not really

Wait

Ok there

Oh i can't send the link

Function- Void sum(int a,int b,int c) In main- See If User Want to do sum of 2 Number(passed as argument) the function will work for 2 numbers. If user want to do sum of 3 Numbers(passed as argument) function will work for 3 number

Use long sum(const int numbers,...)

Then you can do a __clang_error_if() idk

Hello guys, there is something weird with my program. I'd appreciate it if you take a look and advise me. It's a substitution cipher program, where you need to give the key (26 non-repeating alphabetic characters and case insensitive). First I check the key then proceed with ciphering the text. But when using capital letters in the input, my program prints the said symbol twice. https://pastebin.com/9L3CHRus

Sorry, my mistake

Hello everyone

Thanks man

I'm a beginner and I'm Brazilian

Nice to meet you, guys

There are a lot time that I tryna learn C++... I hope this time I could do it

Nice to meet you, guys

hi

I wana ask, where I can practice C to exercise everyday?

Hi , I have a method which have parameter uint64_t& like below fooMethod(uint64_t & number); I have to a variabl of uint32_t unit32_t input; How to do type conversion to pass input into fooMethod without using another variable?

const& will do

const& will do

Or universal ref

const& will do

Please provide full syntax.

Please provide full syntax.

void foo(const uint64_t& a) { .... }

Or void foo(uint64_t&& a) { }

void foo(const uint64_t& a) { .... }

Thanks:). How to call it when I have uint32_t input;

Thanks:). How to call it when I have uint32_t input;

foo(input);

Please provide full syntax.

I have to modify "a", so I can't make them const.Can we do things wihout using universal ref?

Then template parameter

Sorry, my mistake

Lol, it's cool.
