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; ...

readonly keywordreadonly keyword is used to define a variable which can be assigned once after declaration either during declaration or in constructor. const keyword is used to define a constant to be used in the program. Following is the valid usage of a readonly and const keywords in C#.Example Live Demousing System.IO; using System; public class Program {    public const int VALUE = 10;    public readonly int value1;    Program(int value){       value1 = value;    }    public static void Main() {       Console.WriteLine(VALUE);       Program p1 = new Program(11); ...

In this tutorial, we will be discussing a program to find circumference of a circle.For this we will be provided with the radius of the circle. Our task is to calculate and print the circumference of that circle.Example Live Demo#include using namespace std; #define PI 3.1415 double circumference(double r){    double cir = 2*PI*r;    return cir; } int main(){    double r = 5;    cout

In this tutorial, we will be discussing a program to find the circumcenter of a triangle.For this we will be provided with three noncollinear points. Our task is to find the circumcenter of the triangle formed by those points.Example Live Demo#include #include using namespace std; //storing X and Y values #define pdd pair void lineFromPoints(pdd P, pdd Q, double &a, double &b, double &c){    a = Q.second - P.second;    b = P.first - Q.first;    c = a*(P.first)+ b*(P.second); } void perpendicularBisectorFromLine(pdd P, pdd Q, double &a, double &b, double &c){    pdd mid_point = make_pair((P.first + ...

In this tutorial, we will be discussing a program to find the century for a year.For this we will be provided with a year. Our task is to find the century in which the given year falls.Example Live Demo#include using namespace std; void find_century(int year){    //year values can only be positive    if (year

In this tutorial, we will be discussing a program to find area of a circular segment.Making a chord in a given sphere divides it into two segments - major and minor. Given the radius of the circle and angle making the minor segment, we are required to find the areas of both segments.Example Live Demo#include using namespace std; float pi = 3.14159; //finding area of segment float area_of_segment(float radius, float angle){    float area_of_sector = pi * (radius * radius)*(angle / 360);    float area_of_triangle = (float)1 / 2 *(radius * radius) *     sin((angle * pi) ...

In this tutorial, we will be discussing a program to understand partition_point in C++.Partition point is a method which returns an iterator pointing to the first value in a given range. The range is a partitioned one in which the predicate is not true.Example Live Demo#include #include #include bool IsOdd(int i) { return (i % 2) == 1; } int main(){    std::vector data{ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };    std::vector odd, even;    std::stable_partition(data.begin(), data.end(), IsOdd);    auto it = std::partition_point(data.begin(), data.end(),    IsOdd);    odd.assign(data.begin(), it);    even.assign(it, data.end());    std::cout

In this tutorial, we will be discussing a program to understand pair in C++ Standard Template Library.Pair is a container defined in the utility header that contains two values. It is used to combine two values and associate them even if they are of different types.Example Live Demo#include #include using namespace std; int main(){    //initializing a pair    pair PAIR1 ;    PAIR1.first = 100;    PAIR1.second = 'G' ;    cout

In this tutorial, we will be discussing a program to understand override keyword in C++.Override keyword is used to override the function in a base class and define a separate function with the same signature in the child class.Example Live Demo#include using namespace std; class Base {    public:    //function to be override    virtual void func() {       cout
