Does 1<< i depends on the type of i or 1?

Artöm

Yes

Anonymous

what is the limit of 1<< i when i is int and when i is long long

Artöm

Use 1ULL

Artöm

Sizes are 32 and 64

So, 1 << i depends on type of i?

Artöm

Not sure

Artöm

Try cppinsights to figure out

Please am a beginner and I want to ask know the right app for C++ programming

Does 1<< i depends on the type of i or 1?

Type of 1, you can think of it as calling var.operator<<(i); for your custom type, that implements this operator. Where operator will be selected from the type of var.

Pavel

So var << i; the same as var.operator<<(i); so should be for basic types (but for basic types the second won't compile).

Artöm

We discussed it already

Artöm

#include <type_traits> ... static_assert(std::is_same_v<decltype(1 << 4ULL), unsigned long long>);

Artöm

It means, type of second arg doesnt matter

Artöm

Use 1ULL as first arg

I didn't see that you've come to a conclusion there

This satisfies.

You're welcome, just check your problem with google firstly and you'll be a happy person :)

you're right

is this possible if (firstname == "Sam") instead of using strcmp ?

std::string from C++ gives what you want

if I need to use char var[10];

if I need to use char var[10];

No, there's no way then

professor

will I need strcmp right?

Anonymous

will I need strcmp right?

To compare C-style strings? Yes

professor

okay thanks

hey guys , why it always goes to else part if I am checking if its 16 and comparing to 0x393130326F6B45 ? int main() { char buf[8]; int msg; unsigned int v6{}; printf("Enter cookie:\n"); scanf("%s", buf); printf("Your cookie %s \n",buf); if (v6 == 16) { if (stricmp("0x393130326F6B45", buf) == 0) { strcpy(buf, "EkoEko"); printf("cookie %s \n", buf); } else { printf(" [-] Error: Invalid cookie\n"); } } else { printf(" [-] Error: Invalid header\n"); system("pause"); } return 0; }

Because v6 is always 0

professor

It is supposed to catch automatic no?

Artöm

What

professor

I mea instead of writting v6 = 16 , is there other way to catch it 16?

Artöm

Catch from where

Artöm

I didn't quite understand what do you mean by catch

professor

I didn't quite understand what do you mean by catch

I mean should I add add strlen or some count function to check it right or is there to code it as pseudocode

Anonymous

I'm having trouble to understand your question too. Do you mean by "catch" if there is any other way to check if v6 quals to 16? If this is your question, then you can do this with a switch-case block. But this is an overkill if you want to check only for one quality... As Artöm Bakri Al-Sarmini said, v6 is 0 because you initialized it with zero and never assigned any other number to it
