A char is a byte So have 8 bits

How does it shift

When we shift this value (00000001) to left For example shift 2 times It will be 1<<2 00000100

Alright, thanks to both of you

Alright, thanks to both of you

Btw you should use unsigned types for shifting

Btw you should use unsigned types for shifting

for 32-bit signed integers， it is also OK to do shifting operation.

Wow

does anyone here know basic algorithms? can you help me with a theoretical question?

just ask the question already

(a) Show that n(n−1) pn,m≤ 2m . Hint: union bound (and you really only need pairwise independence). Note: This says that if n ≤ √m, then the probability that there is a collision among the Xi’s (i.e., two Xi’s taking the same value) is at most 1/2.

So not your theoretical question but your homework

Bruh thats how this people are hear..braffing over nothing...u ask a question the start given altitude

Maybe you can ask in a algoritm and data structure group

If you wanna use a second vector to implement a matrix.. You can initialize this vector like this... void init(vector<vector<int>>&mat， int m，int n) { mat.resize(m); //for every row in mat for(auto &row:mat) { row.resize(n); std::fill(row.begin(),row.end(),0); } }

#include <iostream> using namespace std ; class Employee { private : int Age ; float bonuses; float basicSalary; public: string occupation; int hours,RateOfPay; void hoursRateOfPay () { cout << "The hours worked by the "<<occupation << " is " << hours << endl; cout << "The rate of pay of the " << occupation<< " is "<< RateOfPay<<endl; } }; int main () { Employee A ; A.occupation = "Engineer" ; A.hours = 25; A.RateOfPay = 49000 ; A.hoursRateOfPay () ; Employee B ; B.occupation = "Accountant" ; B.hours = 19; B.RateOfPay = 30000 ; B.hoursRateOfPay () ; return 0 ; }

Bro that’s what pisses me off! I asked a simple question as respectfully as possible and they go ahead and bash me

Hello! Is it possible for GCC to produce a intermediate file such that another GCC suite could cross-compile it for another architecture?

Nobody bashed you guys here. You're only bashed when you ask a question and don't give an example of the code you've found a bug or error on. If you provided your question with your "try-code", then no one can bashed you. You're only bashed when you want to act lazy, self taught programmers hate that attitude. If it took you 10 hours everyday to learn something and you fully gained expertise on it, then another person comes to learn and start asking questions when not even showing interest, I guess you'll bash them also. So to avoid bashing, ask questions with your code. For questions that don't have code, you can pretty get it quickly from google, so save the stress for the group. Have a nice day

so it will be automatically initialized with 0?

so it will be automatically initialized with 0?

I wonder what is your use-case for that?

Clang definitely can

how print type in c++? i dont like typeid(x),name()

https://github.com/Neargye/nameof

it seems excessive to me ...

aren't there any functions in c ++ that do something so simple?

aren't there any functions in c ++ that do something so simple?

there's __func__

What is good Dev-cpp or visual studio

well, as for a simple way to do that, no.

Dev C++ is not good

Dev C++ is not good

typeid(T).name()

Why

If I recall correctly it isn't supported any more

Are you programmer

yes
