On Exercise 7-3, is there a way we can open LOGICAL2.CPP? Or am I doing the wrong thing all together?

I'm thinking we just do a Word document analyzing the output.

Yes just use a word document analyzing the output, or you can actually create the file. Students do it either way, but the intent is to give you an introduction.

I created a function that uses menu shortcuts and user input to calculate a final cost. This is only my function, not the full program.
The problem that I am having is that I can only enter one character and hit enter. It goes to the next line but does not let me enter any other info or get a return amount. Any suggestions?  insert code here
int Total()
{
char order[21];//orders variable
int total_cost=0;
std::cin>>order;//takes in an order
while (order!="T");//while the total is NOT being called goes through the statement
{
if(order=="S","C","B","R","L") //trys to find menu items in order
{total_cost=total_cost+ 1;}//If an item is called adds a dollar, Could have used total_cost++, or total_cost+=1
return total_cost;//returns cost
}}

Can you post the rest of the program? I'm pretty sure the problem is somewhere outside the function.

Try looping the entire function instead of the looping the case inside the function.
Try putting this format into the main function:
do
function();
while (order!="T");

The rest of my code is mainly just a menu, and then a total.
int _tmain(int argc, _TCHAR* argv[])
{
int x;
std::cout<<"S-sandwich $1 \n";//Simple menu setup
std::cout<<"C-chips $1 \n";
std::cout<<"B-Brownie $1 \n";
std::cout<<"R-Regular drink $1 \n";
std::cout<<"L-Large drink $1 \n";
std::cout<<"B-Brownie $1 \n";
std::cout<<"R-Regular drink $1 \n";
total()*.06=x;// goes to total function which returns added cost of items, then multiplies by sales tax
std::cout<<"Your total is "<<x;
system("pause");
return 0;
}

Also, put the menu display into my function as well, and used a case statement. My main statement is only what I posted above.
