This C++ program demonstrates the count_if algorithm. The count_if takes three arguments – of which the first two are iterators to the beginning and end of the container and the third argument is predicate. The container used here is map which stores name of the companies and their revenue. The predicate checks for companies with … Read more
This C++ program demonstrates the adjacent_find() algorithm. The adjacent_find takes iterator to the beginning and end of a container and an optional predicate as third parameter. The program uses function adjacent_find() to find adjacent pair of elements in which both the elements are same or satisfy boolean true for a predicate passed as a parameter. … Read more
This C++ program demonstrates the find_first_of() algorithm. The function find_first_of() finds the first element from first container which exists in second container. The function takes four iterators – iterators to the beginning and end to the sequence containers. Here is the source code of the C++ program which demonstrates the find_first_of() algorithm. The C++ program … Read more
This C++ program demonstrates the find_if algorithm on string vector. The find_if takes three arguments – of which the first two are iterators to the beginning and end of the container and the third argument is predicate. The predicate we are passing returns true on strings starting with ‘P’. Here is the source code of … Read more
This C++ program creates a vector and uses find() to search for an element. The program creates a vector and uses find() function from algorithm library. The iterator to the beginning and end of the vector is passed as parameter to the function find() and also the key that is to be found. Here is … Read more
This C++ program sorts the heap using sort_heap() operation. The default sort_heap operation sorts the elements of the heap in ascending order. The alternative version of sort_heap can sort the heap depending on the type of predicate and this alternative version takes predicate as its third parameter. The resulting range no longer has the heap … Read more
This C++ program creates a heap using make_heap algorithm. A heap is a way to organize the elements of a range that allows for fast retrieval of the element with the highest value at any moment. The make_heap rearranges the elements in the container in such a way that they form a heap. Here is … Read more
This C++ program pops element from heap using pop_heap algorithm. The pop_heap operation swaps the element at first position and the last position and makes the subrange [first, last – 1) into a max-heap. The element at the last position is actually popped from the container. Here is the source code of the C++ program … Read more
This C++ program pushes elements to heap using push_heap algorithm. A heap is a way to organize the elements of a range that allows for fast retrieval of the element with the highest value at any moment. The push_heap inserts the elements into the heap at last – 1 position where the heap is defined … Read more
This C++ program merges two sequences using inplace_merge() algorithm. This algorithm combines the elements present in the two consecutive sorted ranges [first,middle) and [middle,last) into a combined sorted range [first,last). Here is the source code of the C++ program which merges two sequences using inplace_merge() algorithm. The C++ program is successfully compiled and run on … Read more
