Well, to finish this point there's this http://www.agner.org/optimize/#manual_instr_tab

Why would it take 3 cycles for a single instruction though?

There are two instructions. But a single instructions can take more that one cycle depending upon the function

For (I=0; i<slices;I++) { X=(I+0.5) *0.0006 Cout<<X; Sum+=///// }

But anyway.. as for the amount of elements in the loop, if X is the element in question, then shouldn't slices be your answer?

Slices is the number of interation actually.

Hey , I want to calculate the CPU cycle per iteration . So it should be (Runtime of iterations*Clock_Freq_of_CPU)/( no of iterations * Total elements transfered in total loop )

So but about the Total elements transfered

Yes, and in that loop I see only one element being transferred (to cout) , per iteration, no?

I donno my brain is dead I have been stuck for this for 1 hour 🤣. I'il think again about it now

Well, to finish this point there's this http://www.agner.org/optimize/#manual_instr_tab

Thanks for that

It has a program for measuring it

No worries, happens to the best of us

Hi guys! Can you help me please?! I want shift one column in array, but my experience and Google don't help me ( Example Source array 1 2 3 4 5 6 7 8 9 Results array 1 _ 3 4 2 6 7 5 9 Where 8 will be deleted and _ is empty. if you shared C example, i will be pleasure! thanks!

1. You should save ur column in array 2. Write shiftRight function that returns an array as result 3. result[0] = '_'; 4. set received array into ur column

Hi, I'm C++ beginner I need help to understand below code: #include<iostream> using namespace std; int main() { int x[6] = {19,10,8,17,9,15}; cout << "This numbers are: "; for (int n:x){ cout << n << " "; } return 0; } Result will be as like as: This numbers are: 19 10 8 17 9 15 But my CodeBlocks showing like that: 4354238 4354238 4354238 continue showing without break

works for me bro: /home/jorishdv/CLionProjects/test-cpp-20a/cmake-build-debug/test_cpp_20a These numbers are: 19 10 8 17 9 15 Process finished with exit code 0

hi guys

I know it is a pointer to a void function that gets char* void (*print)(char*); but what is the type of it?

I mean what can I write in typedef

like this typedef sometype myFunPointer;

like this typedef sometype myFunPointer;

It is like declaring a variable. But the variable name be a type name. typedef void (*myFunPointer)(char*); MyFunPointer ptr = theFunc;

hey everyone. i have an object that calls NumberWithUnits that contains 2 data members , double data and string unit. » class NumberWithUnits { double value; string unit; ............ } the mission is to overload the input operator. and i need to succsess in this test : TEST_CASE("<< / >> function after second read") { NumberWithUnits temp_output(2, "r_class"); NumberWithUnits temp_output1(3, "r_student"); ostringstream oss; oss << temp_output << " " << temp_output1; CHECK_EQ(oss.str(), "2[r_class] 3[r_student]"); NumberWithUnits a(7, "r_ILS"); NumberWithUnits b(7, "r_ILS"); NumberWithUnits c(7, "r_ILS"); istringstream iss{" 8 [ r_EUR ] -1 [r_school ] 29.7 [r_halfMin ]"}; iss >> a >> b >> c; CHECK_EQ(a, NumberWithUnits(8, "r_EUR")); CHECK_EQ(b, NumberWithUnits(-1, "r_school")); CHECK_EQ(c, NumberWithUnits(29.7, "r_halfMin")); }

what you are suggest to do?

its really important to me

I dont think that's difficult

Can you send your code to find the problem?

in such case it's better to see what you've tried to help you figure out what you did wrong

it's a reinterpret_cast but you should not use C-style casts in C++

Done

Done

have you tried to compile it? (its just that there's a typo in line 9, and you return a pointer in line 13 while the function is supposed to return an int)

Why did u use 3 for loop for 2d array,

have you tried to compile it? (its just that there's a typo in line 9, and you return a pointer in line 13 while the function is supposed to return an int)

what are you trying to achieve in lines 19-29? you want to sort it?

The typo was from translating. And the return is just a warning

Just put a counter top of your for loop and count occurrence of desired value

yes

The typo was from translating. And the return is just a warning

its not just a warning.... you can convert a pointer to an int, but what do you achieve from it?

count_elems should return the sum of the elements?

man, im learning on my own for fun, just started with c, that's why i'm asking for help. Please, if you want to say anything, give a hint. is bad to convert a pointer to int? idk, nobody told me so (as i said before, its a warning, the code runs and idk how to do it otherway)

count_elems should return the sum of the elements?

I'm trying to help; you don't do anything with the return value, so nothing bad happens. you can just change it to void and don't return anything if you don't need to.

https://t.me/programminginc/383324 what about that? where's the function you had a problem with?

I think a pointer is like a memory address for the data or data types input so calling a pointer is basically calling the address using it isn't wrong but as someone said what do you achieve from it except for calling the memory address

Just what I think

Correction if anything said is wrong

a pointer is a memory address. not like a memory address. so yeah, pointer is also just a number, but what do you get from converting a pointer to an int? he didn't done anything with it, so nothing bad happened, but if you'd try to, for example, convert it back to a pointer, weird things might happen from this conversion since int may be smaller than a pointer.

A pointer its not a memory adress wtf what are saying
