Note you don't have to do the endl on separate lines. Remember the << is a
pipe of sorts so you just shove the stuff from the one side to the other.
So these two do the same thing.
Cout <<"string';
Cout<<endl;
And
Cout <<"string"<<endl;

Hi,
I see. You are already learning switch statement? That's an impressive
progress.
A brief hint: On the following lines, check out the display (cout) code. Do
you notice any difference:
// Jess's version:
cout << "Freshman."; << endl;
// Joseph's version:
cout << "Freshman." << endl;
Notice that there is no semicolon after the text message. If you do put
semicolon, you'll get the syntax error because the compiler couldn't find
the output (cout) operator. A slightly better variation might be:
cout << "Freshman".;
cout << endl;
Another hint (mostly an advice): In the conditional statement, you might
want to try "if" statement versus the "switch" statement. Here's how I would
do it (if I were you):
// Joseph's variation:
// Uses if statement to select a printout message.
if (code == 1)
cout << "Freshman." << endl;
else if (code == 2)
cout << "Sophomore." << endl;
else if (code == 3)
cout << "Junior." << endl;
else if (code == 4)
cout << "Senior." << endl;
else
cout << "Error: invalid code!" << endl;
I (or someone) will explain the previous code in a sec.
Cheers,
Joseph

Hey guys,
Here's a code for an assignment which has to be turned in tomorrow. Every
time I try to compile it, Visual Studio keeps telling me I'm missing a ;
before <<
What's wrong?
Code follows:
//Ch6ConE06.cpp
//Displays a class rank based on a code
//entered by the user
//Created/revised by <your name> on <current date>
#include <iostream>
using std::cout;
using std::cin;
using std::endl;
int main()
{
//declare variable
int code = 0;
//enter input
cout << "Enter the code: ";
cin >> code;
//enter switch statements
switch(code)
{
case 1:;
cout << "Freshman. " ; << endl;
break;
case 2:
cout <<"Sophomore"; << endl;
break;
case 3:
cout << "Junior "; << endl;
break;
case 4:
cout << "Senior" ; << endl;
break;
case 5:
cout << "Error! "; << endl;
}
//endswitch
//display output
return 0;
} //end of main function
Jes
