Yeah lol

So when you don't know at compile time how much memory you need, you can allocate that memory dynamically. In C you would use malloc for that to just get a piece of memory, in C++ you would use new that will also prepare the memory to be safely used with your type. Also there are things like unique_ptr which are even more safe, because whenever you allocate memory you need to free it, otherwise it will be hoarded by the app (leaked), and unique_ptr frees it for you. Have you learned pointers?

If not, I suggest to first learn them, and for now just increase the number from 20 to something reasonable :D

If you did, then the first answer https://stackoverflow.com/questions/4029870/how-to-create-a-dynamic-array-of-integers In reality the second answer with std::unique_ptr is better but std::vector is even more better in most of the cases

Ok

Thank you very much!!

Hi, I am stuck in using TSan, I am currently running gcc 7.5.0 and got ==2220888==FATAL: ThreadSanitizer: failed to intercept strlen, which I cannot find from google... anyone could help?

#include<stdio.h> int digitcheck(int,int); int main() { int num,digit; printf("Enter a number\n"); scanf("%d",&num); printf("Enter the digit\n"); scanf("%d",&digit); int z; int i; for(i=1;i<=3;i++) { z=digitcheck(num,digit); if(z==0) { printf("Our number has that digit on place %d",i); break; } else { num=num/10; } } return 0; } int digitcheck(int x,int y) { int z; z=x%y; return z; }

someone help i want to write a program to check a digit in number input

using function

using function

std::isdigit()

Maybe someone knows how to pass a structure-pair to a function in C++? Will be grateful for any help

What do you mean by structure pair. std pair<>?

What do you mean by structure pair. std pair<>?

pair<int, int> Pair

foo(pair<int, int> a)

foo(pair<int, int> a)

Okey I'm trying. Thank you so much

foo(pair<int, int> a)

I'm sorry. Maybe you know why in compiler I have error like:expected primary-expression before 'PAIR'?

write a program that checks whether the input is palindrome or not

in c++

🙏

I'm sorry. Maybe you know why in compiler I have error like:expected primary-expression before 'PAIR'?

Show full code. Maybe you miss std namespace before pair

I'm sorry. Maybe you know why in compiler I have error like:expected primary-expression before 'PAIR'?

And why pair in caps?

write a program that checks whether the input is palindrome or not

Easy bro

write a program that checks whether the input is palindrome or not

Try your own

Easy bro

i am a fresh student

can you get me the logic

according to my knowledge i should do that with the input number

cin>>num;

NUM%10;

WHAT do you think bro???

Google it

NUM%10;

Logic is correct It will give you remainder

Then again Write a logic to get quotient

but it gives only reminder

Then again Write a logic to get quotient

And then repeat

Using loop

And then repeat

it will give same reminder

Bro google it

You are fresher so it will be hard for me to tell you here

mens if i input 606 its stores 6 every time

okay

it will give same reminder

Try this logic —— Int b , rev=0,remainder; // Using loop remainder = b%10; rev = (rev*10)+remainder; B = b/10; if(rev==num){ cout<<"it is a Palindrome Number";}

Try this logic —— Int b , rev=0,remainder; // Using loop remainder = b%10; rev = (rev*10)+remainder; B = b/10; if(rev==num){ cout<<"it is a Palindrome Number";}

why we divide it with 10

if(rev == b) // it is correct . I used num instead of b

if(rev == b) // it is correct . I used num instead of b

why we divided with 10

why we divide it with 10

When we divide it with 10 we get quotient and when we use % operator we get remainder

It’s Basic maths

When we divide it with 10 we get quotient and when we use % operator we get remainder

let me run it

after running i would be able to understand

Don’t copy just see logic and try it your own … because I didn’t done it full i mean I didn’t wrote full and in proper way if you copy it will give error

Don’t copy just see logic and try it your own … because I didn’t done it full i mean I didn’t wrote full and in proper way if you copy it will give error

i know

i am usng the second logic of number dividing by 10

U have to use both Eg:- m%10 m= m/10

bro what do you think is software engineering a good career

should i continue it or leave it

😅

Take a paper and pencil and write an abstract algorithm without code

Yes

Yes

should i continue it

should i continue it

Probably you shouldn't

Bro if you are into it then u can in my opening almost every one is shifting to it industries

Opinion*

Show full code. Maybe you miss std namespace before pair

#include <iostream> #include <utility> using namespace std; int main() { pair<int, int>PAIR; void displayData(pair<int,int> PAIR); PAIR.first = 100; PAIR.second = 36; displayData(pair<int,int> PAIR); cout << PAIR.first << " "; cout << PAIR.second << endl; return 0; } void displayData(pair<int,int> PAIR) { cout << "\nDisplaying Information." << endl; cout << "Name: " << PAIR.first << endl; cout <<"Age: " << PAIR.second << endl; }

Opinion*

i have interest in programming but neighbours and parents ares forcing me to leave

they say theere are no jobs in this field

Lol

Really?? 😆

And why pair in caps?

For no particular reason, but it's not good?

Any video have any video lectures

For learn cpp

It's ok, but don't make such names

It's ok, but don't make such names

OK, I'll remember. Thank you very much for the answer, you really helped (and thanks for correcting the code, I finally understood what was wrong)

hello please can i get questions to solve

any please

i need questions to answer to practice

Hello, I'm finding trouble running any code on my vscode. Also, I'm seeing an error on Windows PowerShell saying it detected that I'm using a screen recorder and it disabled PSReadline, I don't know if that's what is affecting the vscode, how do I fix this please?

hmmmm... why... maybe because you using it incorrect ?
