Can I return a regular array from a function in C++? No, you cannot return a regular array directly. You can return a pointer to a dynamically allocated array, use std::array, or std::vector. What is the differ
Reverse a vector Toreverse vector elements, we can usereverse() functionwhich is defined in<algorithm>header in C++ standard template library. It accepts the range of the iterators in which reverse operation to be performed and reverses the elements between the given range. ...
Namely, we demonstrate an example that implements a two-data member structure to return an int pair from the function that searches for the maximum/minimum in the vector of integers. Notice that one can define any type of struct to fit their needs and expand the data member count. In this...
In C++, the vector has an empty() function that helps check whether the vector container has elements. Vectors are almost similar to dynamic arrays, which have the facility to resize itself automatically when an item is deleted or inserted, with its storage able to handle automatically by the ...
which(x == 4 | x == 1) # which function with multiple conditions # 1 3 5The previous R code returned each vector index position of elements that are either equal to 4 or equal to 1. We were able to return this result by using the |-operator....

//variable to store the vector size int s = vtr.size() ; //print the vector size cout <<"The vector size is: " << s ; return 0; } Output: In this program, a vector is declared with string elements, unlike the above programs. But, the size() function prints the size of the...

as the element type in move-aware containers, such as std::vector, which hold pointers to dynamically-allocated objects (e.g., if polymorphic behavior is desired) In other words: Everything I dreamed of is already available in the STL: Garbage collection and the possibility to return dynamica...
