hello eve , its ok to ask about BASH COMMANDS?

Is there an easy way to capture arrow keys as input in C++? Or should I give up with them and use simple WSAD with std::cin? I was reading some articles but none of the anwsers was satisfying. Note that I need the program to work on each platform: Windows, Linux and Mac.

use sdl or ncurses

okay thanks

#include<stdio.h> int main() { int i,j,k; printf("enter the no. of rows you want to print "); scanf("%d",&k); for(i=1;i<=k;i++) { for(j=1;j<=i;j++) { printf("%d",k); } printf("\n"); } printf("enter the no. of rows you want to print "); scanf("%d",&k); for(i=1;i<=k;i++) { for(j=1;j<=i;j++) { printf("%d",k); } printf("\n"); } return 0; } I want this loop to be continued so which loop should I use for/while and where to use The output I want 2 22 Then again I press 2 2 22 Then again 2 22 This loop I want

I am a beginner at c++ may a get guider🙏please

Hi, it works a bit differently here. If you have a problem with C++ or a question, and can't google solution to it, you can ask here and people will try to help. Note that it should be a clear question. E.g. if you want to understand why your code works not as intended you can post the code (using code pasting service like pastebin) together with explanation what the code does wrong (and what's the expected behavior of your code).

put the loops in an infinite loop

i am learning stack,queue topic in c I just need some idea in which i can apply these things (I need the ideas in beginner level )

similar to operator precedence right

ALU?

Arithmetic-Logic Unit, now a part of processor but originally it use to come as a separate math-coprocessors.

ALU is to be implemented with the stack

Thanks for the idea man 👍

You understood what he said, I didn't understand.

He said that ALU should me implemented along with stack

Linked list is concrete data structure so it can represent the stack as well

ALU takes/puts operands from/onto the stack

Check if given expression has proper opening and closing brackets.

any eg 😅

any eg 😅

(a+b)*c) - wrong ((a+b)*c) - right

What is the meaning of writing 1 ll

Why don't just write 1

consider 1ll << 33

1ll means, left shift 1 by 33??

So do I need to store i and i*i in long long

In c++ implicit typecasting isn't done?

Ok so it's good that I either do typecasting or I make i as long long

I wrote a code for a problem. For smaller values it runs perfectly. But for larger values it just don't print anything even after taking so much time

#include<iostream> #include<algorithm> using namespace std; #define ll long long int main () { ll l,r; cin>>l>>r; ll max_res=0; for(ll i=l;i<=r;i++) { for(ll j=i+1;j<=r;j++) { max_res=max(max_res,(i^j)); } } cout<<max_res; return 0; }

i^j is xor
