Visual studio and Clion are not for beginners

Ok what should i use?

Which OS do u use?

W10

Lol, visual studio ofc

I m begginer

what's ur problem to go for youtube and learn how to use it for begginer ?????

Ok,what should i use

I meaned thath being a beginener i need a compiler for beginner

just use code blocks don't stress yourself

I see a lot of a screen photos

What's the problem with codeblocks?

how to rotate this in qtcreator

Atom, CodeBlocks... what the **** ?

Gaats,it's you first proj?

Guys,Someone Here Use Atom For C++?

use vim :>

anyone please make it using loops

No

int pow(int a,int b) { int k=0; int arr[10]; while(b>1) { if(b%2==0) { a=a*a; b=b/2; } else if(b%2!=0) { arr[k]=a; a=a*a; b=(b-1)/2; k++; } } if(k>0) for(int i=0;i<k;i++) { a=a*arr[i]; } return a; } int main() { printf("%d",pow(2,27)); }

but optimised way

How would you calculate 2^3?

How would you calculate 2^3?

2*2*2

but optimised way

How would you calculate 2^3?

use std::pow

1 << 2;

Has it more optimization than a simple for loop to multiply a b times?

Most optimized way to calculate powers of 2

2^8=2^4+2^4

Or just 1 << 7

That cannot be done by bit shifting

what about 9^9?

what do u know about bit and bit operations?

int pow(int a,int b) { int k=0; int arr[10]; while(b>1) { if(b%2==0) { a=a*a; b=b/2; } else if(b%2!=0) { arr[k]=a; a=a*a; b=(b-1)/2; k++; } } if(k>0) for(int i=0;i<k;i++) { a=a*arr[i]; } return a; } int main() { printf("%d",pow(2,27)); }

But you can do (b>>1)&1 . if it returns 1, it is same as b%2==0
