The vector is a useful container class of C++ to store the sequence of data that works as a dynamic array. The insert() function is used to add one or more new elements before the specific element of the vector object by mentioning the position of that e

Each member functions inserts, before the element pointed to by it in the controlled sequence, a sequence specified by the remaining operands. The first member function inserts a single element with valuexand returns an iterator that points to the newly inserted element. The second member function...
This post will discuss how to insert an element at the beginning of a vector in C++. The standard solution to insert an element to a vector is with the `std::vector::insert` function.
