EduardoBrito's blog

Hello everyone!

I want to offer you a blog about the STL of C++11, a few weeks ago I was reading interesting information about this topic in GeeksforGeeks, and today I decided to share this information through this blog for all those interested. In advance, I want to thank all those who pay attention and interest to this blog, and thank any comments about it (positive or negative). Well, let's start now.

I will start with some array algorithms in the C++11 STL, which I did not know before and that can have a very interesting use, depending on the problem.

Array algorithms: these algorithms operate on an array and are useful in saving time during coding and hence useful in competitive programming as well.

all_of(): this function operates on whole range of array elements and can save time to run a loop to check each element one by on. It checks for a given property on every element and returns true when each element in range satisfies specified property, else returns false.

Code

any_of(): this function checks for a given range if there’s even one element satisfying a given property mentioned in function. Returns true if at least one element satisfies the property, else returns false.

Code

none_of(): this function returns true if none of element satisfies the given condition, else returns false.

Code

iota(): this function is used to assign continuous values to array.

Code

accumulate(): this function returns the sum of all the values lying in a range between [first, last) with the variable sum.

Code

Thank you to all

Thanks for share! I have a question the time complexity of those functions is linear?

what does the following do?

ios_base::sync_with_stdio(0); cin.tie(0); cout.tie(0);

I tried implementing them in python and here are the codes except for none_of but you can do it using all() and not keywords.

all_of
any_off
copy_n
iota
accumulate
