Homework 2 due April 21

1.	Output produced from question 1:

endlendl
grendel 

//at the end of cout, no new line was established so just adds on to current line.  Once endl; was entered cursor moves to new line..type variable = assigned a string (initialized in declaration)

2. This program asks you to "Enter a number:" and assigned the number to the identifier len.  the program only produced output if the number > 0.  if you enter in 5, the program produces a forward slash shaped line of # signs spanning a number of lines = to len.  if you enter in a double it spans a number of lines = to the interger value len.  


FROM SOLUTIONS:
It prints a diagonal line of the specified length. 


//original program	
#include <iostream>
#include <string>
using namespace std;
 int main()
	{
	    int len;

	    cout << "Enter a number: ";
	    cin >> len;

	for (int i = 0; i < len; i++)
	{
		  for (int j = i+1; j < len; j++)
	    {
		    cout << " ";
	    }
		  cout << "#" << endl;
	}
	}




3. //inner loop is while loop

#include <iostream>
#include <string>
using namespace std;
int main()
	{
	    int len;

	    cout << "Enter a number: ";
	    cin >> len;
	    
	    for (int i = 0; i < len; i++)
	    {
	      int j = 1+i;
	      while (j < len)
		{
		    cout << " ";
		    j++;
		}
		  cout << "#" << endl;
	    }
	}




	
4.// do while loop for outer loop

#include <iostream>
#include <string>
using namespace std;


int main()
{
	int len;

	cout << "Enter a number: ";
	cin >> len;

 int i = 0;
do {
 	 for (int j = i+1; j < len; j++)
	{
		    cout << " ";
	}
	cout << "#" << endl;
	i++;
	} while (i<len);
	return 0;
	
	}


//correct way from SOLUTIONS
#include <iostream>
using namespace std;

int main()
{
    int len;

    cout << "Enter a number: ";
    cin >> len;

    if (len > 0)  // No output whatsoever if len is nonpositive
    {
        int i = 0;
        do
        {
            int j = i+1;
            while (j < len)
            {
                cout << " ";
                j++;
            }
            cout << "#" << endl;
            i++;
        } while (i < len);
    }
}   
	

5. 
switch (codeSection)  //controlling expression
{
	case 281:
		cout << "bigamy";
		break;
	case 321:
	case 322:
		cout << "selling illegal lottery tickets";
		break;
	case 383:
		cout << "selling rancid butter";
		break;
	case 599:
		cout << "artificially coloring a live rabbit";
		break;
	default:
		cout << "some other crime";
}
