If you want to iterate over your list you can iterate over elements of std::map as well. But if you iterate more often than search/add/remove, then std::vector may be more efficient

I should make a blog post on how much deque is overlooked and put some benchmarks comparing it to vector

The general idea should often be to use either vector or deque if you don't know what to use, and measure if performance comes into question. the number of times I see people using std::map to store less than 20 elements when std::vector with a linear search is order of magnitudes faster is mind boggling

Does anyone has a good link for Dijkstra algorithm for shortest h path in a double linked list?

Hi

It's allowed to make some questions about assembly here? The problem that I have it's not related with C/C++ already but it's probably involve it in some time

hey what is the time complexity of this loop? i=2 while(i<n) { i = i * i * i; } i think it’s definitely logarithmic and what i came with is (log i^2(n)) but i felt like it doesn’t make sense

Given an Nx N grid G and each cell of the grid contains an integer. In one step you can travel from any cell G, to Gid if abs(ji-j2)+abs(i1-12) ≤ p at a cost of floor(G). Here p is the number of unique prime factors of the integer at Gij. Find the minimum cost to move from the top-left corner cell to the bottom-right corner cell, no matter how many steps you take. Notes abs(x) means taking the absolute value of a number x or Ix. ⚫ floor(x) represents the largest integer y such that y<x. . V represents the square root of x. • Use 1-based indexing Write a code in c++

Anyone im a beginner so help me with this can we make UI / GUI in C++? or i need to learn another language for it?

qt framework?

what is that sir?

A general graphics class library

Hey computer scientist cuz of danya i search about Qt and im not clear on some things does Qt provide a open source library like math.h ,etc or we must download the Creator to use in windows cuz i dont got one :)

Can anyone explain pointers in simple words

int *p=&n; for (int i = 0; i < n; i++) { printf("%d ",*(&arr[0]+i)); } for (int i = 0; i < n; i++) { printf("%d ",*(&arr+i)); } isn't both method of print an array using pointers same? as both &arr and &arr[0] refers to starting address of the array. I am getting wrong output while using the second method.

The first way is correct i think

why not the second one? aren't they same thing?

No, they are not

& is not needed

Hi all. Can anyone please help me with any recorded videos or course on Pro*C? I checked all the major learning websites. Could not find any!PLease help

is it correct to use float with % ?

If you're talking about modulo, you're searching for fmod(), if you're talking about printf format strings you're thinking of "%f", if you're talking about fractions, depending on your use case it's probably fine to store fractions as floats

i mean this ——> example: 3.0(as a float)%2(as float or int )

And you're expecting 1.0 as a result?

yeah ! but its incorrect

In that case, you're talking about modulo, use fmod() or fmodf()

Are you sure you don't want 2.631?

yes but its not important .

Just use sprintf() to convert to a string, reverse it, use atof() to convert back
