so int t {n};

School sport event... For week

Good event!

Adn good luck with it

But.. how am I supposed to retrieve the value of n once the loop exists

What?

But.. how am I supposed to retrieve the value of n once the loop exists

See it is intialised with int I hope u can return

In do_while loop, use z In for loop, use z and rest

What?

U see.. I used while loop to detect how many digits am entering right.. but eventually the value of n is 0 and loop exists... Now I need the default value of number to reverse it..

Don't use n inside loops

Alright.. it's working thnx man😁

Hey everyone I'm having one little problem here

The problem is described here: https://www.hackerrank.com/challenges/compare-the-triplets/problem

And the solution I came up is this: https://raw.githubusercontent.com/redhackthings/Code_Practice/master/Compare_Triplets/compare_triplets.cpp

But don't Know why Abort is called when the score should be 0 0

Your array can only hold 2 elements. While indexing is 0-based, the size is not.

Why? I gave i<=2 right?

Yes, but a[1][2] reserves space for 1*2 ints

You probably wanted a[2][3] ?

Oh, okay. But everything is fine for anyother case

You probably wanted a[2][3] ?

Okay I'll try this

Oh yes it worked

Oh, okay. But everything is fine for anyother case

Accessing array elements out of bounds is undefined. It may but is not required to work.

Oh yes it worked

👍🏻

Actually I'm new to C++ 14 so didn't know the proper working, thanks for helping me out

You're welcome :) those arrays work the same in c btw

I found it strange that while defining the array if I do this int a[1,2] then the compiler gives error

Even I think the same.

That is no valid c or c++ syntax.

But I learnt that way and it used to work.

Is it old syntax?

It has never been iso c or c++ conformant. I only know this syntax from C#

Oh actually I learnt C++ from some old book ( time when people used Turbo C++ or Borland C++)

Its possible they have added it as language extensions, I never used them though

Oh wait you're correct

same here, I was just confused

Even I have not used it that way in C++

Sorry my bad

I just forgot

Oh okay, no problem :)

Yes, but a[1][2] reserves space for 1*2 ints

does a[0][0] won't exist if if initialize it like a[1][2]?

does a[0][0] won't exist if if initialize it like a[1][2]?

When you have int a[1][2]; you can access a[0][0] and a[0][1] I hope this answers your question, not sure I got it

You can always access each dimension at index 0, since each dimension is required to be at least of size 1

oh got it

Good event!

No

Have I?

I hope you win this shit~

No, promotions are not allowed

What is this group about?

Hello guys

lol no

lol only later I did realize that @programminginc (this group) is read as “programming in c”, not “Programming Inc.”

Hi! How come %10 returns the last digit in a number? For instance 597%10 returns 7.

How did I guess? :D

Hi! How come %10 returns the last digit in a number? For instance 597%10 returns 7.

It doesn't

A%B returns the rest of the division A/B

Ohh can't post SO links here?

If B = 10, it's obvious it will return the last digit

Ohh can't post SO links here?

No links if you're a new member

It doesn't

That was misleading :/ sorry

Ohhh, so in my case, 597%10 = 7 because 597/10 = 59.7 @Occupato ?

Ohh so this is modulus operator, not something in C++ to return the last character right?

Ohhh, so in my case, 597%10 = 7 because 597/10 = 59.7 @Occupato ?

Nope, because 597 / 10 == 59 w/ rest == 7

I just realised am a very bad coder😂😂

☺ Newbie here, teaching myself C++ and solving small problems.

Got it now @Occupato. TY so much!

No problem :)

Yep

Ohhh, so in my case, 597%10 = 7 because 597/10 = 59.7 @Occupato ?

579 is an integer or a float?

It's obv an int

O then 597/10 will be 59.. not 59.7

O then 597/10 will be 59.. not 59.7

Yep

^

I meant.. if he declared 597 as an integer or float😅

No

Yes but u can also store numbers without decimal..

597 is a literal, thus is only an int :P
