Question
The following program will display the days for a month of the year. The input to the program is the
number of days and the day of the week on which the first day of the month falls.
The following program uses for loops to draw a rectangle of desired size.
// P43a.cpp - This program displays the days of a month
// Day 0: Sunday, Day 1: Monday, Day 2: Tuesday
// Day 3: Wednesday, Day 4: Thursday, Day 5: Friday
// Day 6: Saturday
#include<iostream>
#include<cmath>
using namespace std;
int main()
{
}
int n_days, start_day;
cout << "Enter the number of days, 28, 29, 30 or 31 \n";
cin >> n_days;
cout << "Enter the first day of the month \n";
cin >>start_day;
cout << "Sun\tMon\tTue\tWed\tThr\tFri\tSat\n";
for(int i = 0; i < start_day; i++)
{
cout << "\t":
}
for(int j = 1; j <= n_days; j++)
{
if(j%7 == 0)
cout << endl;
cout <<j << "\t";
}
cout << endl;
return 0;
Exercise 4.4
Modify the above program such that it uses a function called display_month(int n_days, int start_day)
to display the days of a month. Call your new program ex44.cpp. In the new program, replace the
following segment:
