10,035 PointsC ++ Branching/ Switch
Need some help with this assignment before the deadline .
Topic
Branching
switch Statement
Description
Enhance the last assignment to include input validation. The enhanced assignment should check the values of day, month, and year entered by the user to ensure that they are OK. If they are not OK, the program should display an error message and return. The program should check the input values before computing the day number.
The program should validate the input values to ensure that:
· Year value is from 2000 to 2099 inclusive.
· Month value is from 1 to 12 inclusive.
· Day value is valid for the given month and the year.
Testing
Input Test Run 1
Enter Month: 4
Enter Day: 31
Enter Year: 2003
Output Test Run 1
Mismatching Month/Day Values Entered.
Month Value Entered: 4
Day Value Entered: 31
Input Test Run 2
Enter Month: 3
Enter Day: 31
Enter Year: 201
Output Test Run 2
Unacceptable Year Entered 201.
Acceptable range For Year is 2000 to 2099
Input Test Run 3
Enter Month: 2
Enter Day: 29

Output Test Run 4
Date: 2/29/2004
Day Number: 60
Input Test Run 5
Enter Month: 3
Enter Day: 1
Enter Year: 2003
Output Test Run 5
Date: 3/1/2003

But use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. Or watch this video on code formatting.

10,035 PointsQuestion is on how to use switch statement in c++ language ignore the java code . for example: I have written this code for the program but still don't ask for the input and output that teachers want.
#include<iostream>
using namespace std;
/*
The code below asks the user to input month, day and year one after the other.
It then validates the values entered. If any of the values is invalid,
it displays an error message and returns.
*/
//main function
int main()
{
int day, month, year;
//input day, month, and year values here.
cout<<"Enter Month:";
cin>>month;
cout<<"Enter Day:";
cin>>day;
cout<<"Enter Year:";
cin>>year;
//Declaring leapyear variable
bool leapyear = false;
if ((year % 4) == 0)
{
leapyear = true;
}
//Validating YearValue
if (year < 2000 || year > 2099)
{
cout <<"Unacceptable Year Entered: "<< year << endl;
cout <<"Valid Range For Year 2000 to 2099 "<< endl;
return 0;
}
//Validating Month Value
if (month < 1 || month >12)
{
cout << "Invalid Month Entered: " << month << endl;
return 0;
}
//Validating Day Value
if ((day < 1)||(day >31 ) )
{
cout << "Invalid Day Entered: " << day << endl;
return 0;
}
//Validating Other Day Values
if (( month == 4 || month == 6 || month == 9 || month == 11) && ( day > 30 ) )
{
cout << "Mismatching Month/Day Values Entered. " << endl;
cout << "Month Value Entered: " << month << endl;
cout << "Day Value Entered: " << day << endl;
return 0;
}
if ((month == 2) && ( day > 29 ) && ( leapyear ) )
{
cout << "Mismatching Month/Day Values Entered. " << endl;
cout << "Month Value Entered: " << month << endl;
cout << "Day Value Entered: " << day << endl;
return 0;
}
if ( (month == 2) && ( day > 28 ) && (!leapyear ))
{
cout << "Mismatching Month/Day Values Entered. " << endl;
cout << "Month Value Entered: " << month << endl;
cout << "Day Value Entered: " << day << endl;
return 0;
}
// Determining day number and your day calculation start here
int dayNum;
//Finally If your execution reaches here
switch (month) {
case 1: //Checking for Jan
dayNum = day;
break;
case 2: //For Feb-> Adding Current days and Jan
dayNum = day + 31;
break;
case 3: //March -> adding for current month and for Jan and Feb

case 5: //May

case 6: //June
dayNum = day + 31 + 28 + 31 + 30 + 31;

case 7: //July

//add 1 for a leap year
if (leapyear==true && month > 2)
{

Python Web Development Techdegree Student 38,322 PointsA quick search on google gave this example from MSDN :-)
// switch_statement1.cpp
#include <stdio.h>
int main() {
char *buffer = "Any character stream";
int capa, lettera, nota;
char c;
capa = lettera = nota = 0;
while ( c = *buffer++ ) // Walks buffer until NULL
{
switch ( c )
{
case 'A':
capa++;
break;
case 'a':
lettera++;
break;
default:
nota++;
}
}
printf_s( "\nUppercase a: %d\nLowercase a: %d\nTotal: %d\n",
capa, lettera, (capa + lettera + nota) );
}
