insert

Description : insert() is a function in C++ STL which inserts new elements before the element at the specified position, effectively increasing the container size by the number of elements inserted.

Example:

    // initialising the vector 
	std::vector<int> vec = { 10, 20, 30, 40 }; 

	// inserts 5 at front 
	auto it = vec.insert(vec.begin(), 5);  

	std::cout << "The vector elements are: "; 
	for (auto it = vec.begin(); it != vec.end(); ++it) 
		std::cout << *it << " "; 
	std::cout << std::endl;
