C++ program using two constructor to calculate minutes and seconds with hour as input from user

Write a class with name Time. Make a constructor which calculates the given time in minutes {if input time is 1hr, then the constructor should return 60minutes. }. Make another constructor which calculates the time in seconds. { if the input time is 1hr, then the constructor should return 60*60=3600 seconds}. Display the contents of both the constructors

#include<iostream.h>
#include<conio.h>

class Time
{
public:
	Time(int);
	Time(float);
};

Time::Time(int b)
{
	cout << "Time in seconds: " << b*60*60 << "n";
}
Time::Time(float b)
{
	cout << "Time in Minutes: " << int(b*60) << "n";
}

void main()
{
	clrscr();
	int hr;
	cout << "Enter the time in Hours: ";
	cin >> hr;
	Time t1(hr);
	Time t2(float(hr));
	getch();
}

#include<iostream.h>

#include<conio.h>

class Time

{

public:

Time(int);

Time(float);

};

Time::Time(int b)

{

cout << "Time in seconds: " << b*60*60 << "n";

}

Time::Time(float b)

{

cout << "Time in Minutes: " << int(b*60) << "n";

}

void main()

{

clrscr();

int hr;

cout << "Enter the time in Hours: ";

cin >> hr;

Time t1(hr);

Time t2(float(hr));

getch();

}

Output

Enter the time in Hours: 1

Time in seconds: 3600
Time in Minutes: 60

Enter the time in Hours: 1

Time in seconds: 3600

Time in Minutes: 60

Program in C++ to find weekday based on weekday number

The below program in C++ will find out weekday based on the weekday number input. We will be following the below logic. 1 -> Sunday 2 -> Monday 3 -> Tuesday 4 -> Wednesday 5 -> Thursday 6 -> Friday 7 -> Saturday Here we are accepting the week day number as input from the user and use switch statement to display the weekday. Below is the program in C++.

#include<iostream.h>
#include
#include
void main(){
	int day;
	clrscr();
	cout << "Enter the day number: "; cin >> day;
	switch(day){
		case 1:
			cout << "nIts Sunday";
			break;
		case 2:
			cout << "nIts Monday";
			break;
		case 3:
			cout << "nIts Tuesday";
			break;
		case 4:
			cout << "nIts Wednesday";
			break;
		case 5:
			cout << "nIts Thursday";
			break;
		case 6:
			cout << "nIts Friday";
			break;
		case 7:
			cout << "nIts Saturday";
			break;
		default:
			cout << "nPlease enter number between 1 to 7";
			break;
	}
	getch();
}

#include<iostream.h>

#include

void main(){

int day;

clrscr();

cout << "Enter the day number: "; cin >> day;

switch(day){

case 1:

cout << "nIts Sunday";
