Write a program in c++ using only if statements that prompts the user to enter an integer for today’s day of the week (Sunday is 0, Monday is 1 …., and Saturday is 6) then displays today. Also, prompt the user to enter the number of days after today for a future day and display the future day of the week.

The future day can be computed as follows:

(today + number of days after today) % 7

Sample run 1:

Enter today's day (Sunday is 0, Monday is 1 ..., and Saturday is 6): 1

Today is Monday.

Enter the number of days elapsed since today: 31

The future day is Thursday.

Sample run 2:

Enter today's day (Sunday is 0, Monday is 1 ..., and Saturday is 6): 10

Invalid number ...

how can i fix my code:

#include

using namespace std;

int main()

{

int day, num;

cout<<"Enter today's day (Sunday is 0, Monday is 1 ..., and Saturday is 6): ";

cin>> day;

if(day==0)

{

cout << "Today is Sunday." << endl;

}

else if(day==1)

{

cout << "Today is Monday." << endl;

}

else if(day==2)

{

cout << "Today is Tuesday." << endl;

}

else if(day==3)

{

cout << "Today is Wenesday." << endl;

}

else if(day==4)

{

cout << "Today is Thursday." << endl;

}

else if(day==5)

{

cout << "Today is Friday." << endl;

}

else if(day==6)

{

cout << "Today is Saturday." << endl;

}

else

{

cout << "Invalid number ..." << endl;

}

cout << "Enter the number of days elapsed since today: ";

cin >> num;

int futureday = ((day+num)%7);

if(futureday==0)

{

cout<<"The future day is Sunday." << endl;

}

else if(futureday==1)

{

cout<<"The future day is Monday." << endl;

}

else if(futureday==2)

{

cout<<"The future day is Tuesday." << endl;

}

else if(futureday==3)

{

cout<<"The future day is Wenesday." << endl;

}

else if(futureday==4)

{

cout<<"The future day is Thursday." << endl;

}

else if(futureday==5)

{

cout<<"The future day is Friday." << endl;

}

else

{

cout<<"The future day is Saturday." << endl;

return 0;

}}
