In this article we will be discussing the working, syntax and examples of map::key_comp() function in C++ STL.What is Map in C++ STL?Maps are the associative container, which facilitates to store the elements formed by a combination of key value and mapped value in a specific order. In a map container the data is internally always sorted with the help of its associated keys. The values in the map container are accessed by its unique keys.What is map::key_comp()?The map::key_comp( ) is a function which comes under header file. This function returns a copy of a key comparison object. This ... Read More

== operator== operator compares the operands by checking the equality of values of objects.is operatoris operator compares the operands by checking the objects to be the same or not.ExampleFollowing is the program in Python to showcase the difference. Live Demolist1 = [1] list2 = [1] list3 = list1 print(id(list1)) print(id(list2)) if (list1 == list2):    print("True") else:    print("False") if (list1 is list2):    print("True") else:    print("False") if (list1 is list3):    print("True") else:    print("False")Output140380664377096 140380664376904 True False True

Problem StatementGiven two time periods in the string 'HH:MM: SS' format. Here 'HH' represents hours, 'MM' represents minutes and 'SS' represents seconds. Find the difference in the same string format between these two time periods.Time period 1 = 8:6:2 Time period 2 = 3:9:3 Time Difference is 4:56:59ExampleFollowing is the program in C++ to find the required output. Live Demo#include using namespace std; int main() {    int hour1, minute1, second1;    int hour2, minute2, second2;    int diff_hour, diff_minute, diff_second;    cout minute1 >> second1;    cout minute2 >> second2;    if(second2 > second1) {     ...

out keywordout keyword is used to pass arguments to method as a reference type and is primary used when a method has to return multiple values. ref keyword is also used to pass arguments to method as reference type and is used when existing variable is to be modified in a method. Following is the valid usage of ref and out keywords in C#.Example Live Demousing System.IO; using System; public class Program {    public static void update(out int a){       a = 10;    }    public static void change(ref int d){       d = 11; ...
