scanner questions

[joshdgreen]

Wow, that sucks man. Are you familiar with loops and such to complete the program the right way?

[socboy6579]

i know. im so mad. i dont know what im going to do. this program is due tomorrow. but if i were have to use loops. whould i need a scanner. because i could just put numerical values for a,b,c,d,f and then find the average of letter grades that you output. correct?

[joshdgreen]

You still need Scanner either way to input any data at all. I tried coding the program myself and am almost done with it actually. It is more advanced stuff than you probably know how to do at the moment.

[socboy6579]

would you mind to show me your program? to give me an idea. im trying it right now. but i always seem to get stuck. these programs are ahead of what we learn idk why our teachers do this.

[joshdgreen]

When I'm done I will give you hints and help, but I won't just give you the code.

[socboy6579]

okay thank you.. would we use both for and while loops ?

[joshdgreen]

Probably, although you can use them interchangeably.

[socboy6579]

could you give me a hint on how to get the letter grades to be assigned to a numerical GPA value using the loops. im stuck there

[joshdgreen]

Here's a little something to get you started:

Scanner keyboard = new Scanner(System.in);

double classCount = 0;
boolean valid = true;
// More variables...
		
while(valid == true)
{
     //Keep getting grades until a "non-grade" is entered.
     //Keeping track of classCount as good grades are entered.
}		

for(int i = 0; i < classCount; i++)
{
     //Do manipulations and place your if statements here.
     //Keep a running total for the GPA.
}
		
// Calculate the total GPA
// Output appropriately

You would check to see what grade it is, and then add to the GPA sum appropriately.

Keep posting updated portions of you code so we can see where you are at.

what is that for loop for again? im sorry im just very confused

You don't need it, I was just giving something to look at to give you ideas.

I noticed the yahoo post some time ago - but is it a cross post of the OP? Well I guess only the OP can say...

There are a number of instances of this problem (wording always the same) and questions about it across the web from 2002 onwards.

That yahoo question was posted today and is almost word-for-word the original post.
