Note: When we remove a single element, the iterator passed must be dereferenceable. Syntax: For removing a single element: vector_name.erase(iterator position); //remove using positionExample: vector1 = {10,20,30}, iterator=2 vector.erase(iterator); Output: 10, 20...
Remove Duplicates From a Vector in C++ Using std::sort and std::unique With resizeWhen tasked with removing duplicate elements from a vector, we have seen that the combination of std::sort and std::unique is a convenient choice. However, an alternative approach is to use the resize ...
Usestd::eraseandstd::removeFunctions to Remove Element From an Array in C++ Another scenario for this problem occurs when the given array is of typestd::vector. This time, we have the dynamic array features, and it’s more flexible to use a built-in function for element manipulations. ...
I have added what i thought were missing Sile specification and got no where with it and i have looked into how to get rid of the problem and have got nowhere the code that makes the error occur is / cout << ip << endl; how do I remove the error without removing the code? All ...
myvector =name of the vector of vector So the outer vector can be thought of as a vector (1D) whose element is also a vector. Advantages for vector of vectors compared to 2D array, is that one can expand vector as much as he wants. Like, you have no restriction for size. For ex...

Note:Here, I have used begin() and end() where begin() is used to return an iterator that is pointing to the first element of the vector, and end() is used to return an iterator that is next to the last element of the vector. Besides the begin() and end() if you want; you ...

You can use dynamic_pointer_cast, static_pointer_cast, and const_pointer_cast to cast a shared_ptr. These functions resemble the dynamic_cast, static_cast, and const_cast operators. The following example shows how to test the derived type of each element in a vector of shared_ptr of base...
