STL Algorithm std::unique Tutorial
In this example we will discuss std::unique STL Algorithm. std::unique is a n STL Algorithms that provide a functionality to remove all consecutive duplicate elements from a given range. Advertisements For example, we have an array of elements i.e. 1,2,3,3,3,4,4,5,5 Frequently Asked: STL Algorithm std::unique Tutorial As we can see above there are 4 consecutive …
STL Algorithm – std::sort Tutorial and Example
In this article we will discuss STL Algorithm std::sort algorithm. std::sort is a STL Algorithm which provides the functionality of sorting a given range of elements. To use std::sort we need to pass start and end of range in it as an argument i.e. Advertisements std::sort (<START OF RANGE> , <END OF RANGE>); For example, we …
C++ : How to copy / clone a STL List or Sub List
In this article we will discuss different techniques to clone the whole list or copy just a sub list. Suppose we have a std::list of strings i.e. Advertisements // List of strings std::list<std::string> listOfStrs = { “of”, “is”, “from”, “this”, “at”, “to” }; Now let’s see how to copy this or a sub list from …
C++ : Case-insensitive string comparison using STL | C++11 | Boost Library
In this article we will discuss different ways to Compare strings in case insensitive manner. Suppose we have two strings i.e. Advertisements std::string str1 = “Hi This is SamPle”; std::string str2 = “hi this is sample”; Both the above strings should be equal if we compare them in case insensitive manner.
