Question

Write a program to find number of days in a month:

• Header comments must be present
• Prototypes must be present
• Use comments and good style practices

NOTE: For simplicity, we will ignore leap years (i.e. February will always have 28 days).

main() function:

• Display hello message
• Call getMonth and assign result to month
• Call getDaysInMonth and assign result to days
• Display results
• Display goodbye message

getMonth() function:

• Prompt user for month
• Loop until month is between 1 and 12
• Return month

getDaysInMonth() function:

• Switch on month to find days
• Return days

SAMPLE RUN:

Welcome! This program will display how many days are in a month selected by the user.

Enter a month (1-12): 7

There are 31 days in that month.

Exiting program. Goodbye!

Answer 1

CODE

#include <iostream>

using namespace std;

int getMonth();

int getDaysInMonth(int);

int main() {

cout << "Welcome! This program will display how many days are in a month selected by the user." << endl;

int month = getMonth();

int days = getDaysInMonth(month);

cout << "There are " << days <<" days in that month." << endl << "Exiting program. Goodbye!";

}

int getMonth()

{

int month;

cout << "Enter a month (1-12): ";

cin >> month;

while(month > 12 || month < 1)

{

cout << "Enter a month (1-12): ";

cin >> month;

}

return month;

}

int getDaysInMonth(int month)

{

switch(month)

{

case 2:

return 28;

case 1:

case 3:

case 5:

case 7:

case 8:

case 10:

case 12:

return 31;

case 4:

case 6:

case 9:

case 11:

return 30;

}

return -1;

}

OUTPUT

Welcome! This program will display how many days are in a month selected by the user.
