When we use the Linux or UNIX operating system, we need to include “unistd.h” header file in our program to use thesleep ()function. While using the Windows operating system, we have to include “Windows.h”
Given a vector and we have to reverse their element using C++ STL program. 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 perf...
Given two vectors and we have to join them using C++ STL program.Joining two vectors To join two vectors, we can use set_union() function, it accepts the iterators of both vectors pointing to the starting and ending ranges and an iterator of result vector (in which we stores the result...

range-based STL functions on it. In this case, we use thestd::sortfunction from the STL algorithms on each string. Here, we utilize the simplest overload of thestd::sortfunction, which takes two iterator arguments to traverse the range and sort the elements by default in non-descending ...
#include<phpcpp.h>/** * Bubblesort function in C++ * * This function takes an unsorted array as input, sorts it, and returns * the output. Notice that we have not really done our best to make the * implementation of this function as efficient as possible - we use stl * containers ...
More practically, it is more expensive to use sort or find to get an element in a list container with the generic algorithms than to do the same operation on a vector. As a result, the list container type provides its own class methods, which are more efficient than the generic algo...
Removal of duplicate elements from a vector in C++ can be efficiently achieved using the combination of std::sort and std::unique, two powerful functions provided by the C++ Standard Template Library (STL).The std::sort function is used to sort the elements in a specified range. In the ...
Thus, we go for make files and we use to make a tool to build the project and generate the executable. We have already seen various parts of a make file. Note that the file should be named “MAKEFILE” or ‘makefile’ and should be placed in the source folder. ...
However be sure to profile that the creation/destruction cycle is actually a problem. Another way is a tight loop in a function that does this, factor it out of the loop, or a loop spamming a function, pass the item in rather than create it inside, and so on. Just moving the create...
