Question

Create a function called time2Greeting.

It takes a time (in military time) and returns a string with the right greeting.

Good Morning 4AM to before noon.

Good Afternoon Noon to before 5PM

Good Evening from 5PM to 11PM

What are you doing up at this hour? between 11 and 4AM

For illegal values, say:

Answer 1

Please find the C++ code for the following:

Code:

#include <iostream>
#include<cstring>
using namespace std;
//Defined a method which takes a time (int) and returns a string with the right greeting.
string time2Greeting(int militaryTime)
{
//Check for - 4AM to before noon.
if(militaryTime>=0400 && militaryTime<1200)
return "Good Morning";
//Check for - Noon to before 5PM
else if(militaryTime>=1200 && militaryTime<1700)
return "Good Afternoon";
//Check for - from 5PM to 11PM
else if(militaryTime>=1700 && militaryTime<2300)
return "Good Evening";
//Check for between 11 and 4AM
else if( (militaryTime>=2300 && militaryTime<2400) || (militaryTime>=0000 && militaryTime<0400))
return "What are you doing up at this hour?";
//Else part
else
return "That is not a valid time.";

}

int main()
{
string name;
int Mtime;
  
//Prompt the name and time from the user
cout<<"What is your name? ";
cin>>name;
cout<<"What time is it? ";
cin>>Mtime;
  
//call the function and then print the output
cout<<time2Greeting(Mtime)<<", "<<name;

return 0;
}

Please check the compiled program and its output for your reference:
