How to declare a GPA formula...

Please help me,.....I don't know how to make an input for GPA formula....for GPA calculator for 7 subjects (max)...

So...how to make a formula?....

Gred:

A=4.00,
A-=3.67,
B+=3.33,
B=3.00,
B-=2.67,
C+=2.33,
C=2.00,
C-=1.67,
D+=1.33,
D=1.00,
E=0.00

Total GPA = Total of (gred points x credits hour)/total of credits hour

Well you seem to already have the formula, you just need a way to represent it in code I'm guessing? So let's deal with each part of your formula and see what we need.

First, you need the grade points for each course as well as the credit hours for each course. Well, you already have the credit hours for each course because you stored them in credits1 through credits 7. The problem is you never keep all the grade points for each course. You can do this at the same time that you are printing out the grade for the course. For example:
[code=c++]
if( score > 79 ) {
printf( "Grade A\n" );
grade1 = 4.00;
}
else if( score > 74 ) {
printf( "Grade A-\n" );
grade1 = 3.67;
}
// and so on
[/code]

Now we can find the Total( grade points * credit hours ) by simply summing them up like this:
[code=c++]
total = grade1 * credits1 + grade2 * credits2 // and so on
[/code]

So now you just need the total credit hours, but you can find this by just adding up the credits1 + credits 2, etc.

Now you just perform the division and voila!

In your question you also mentioned that you wanted to calculate this for a MAX of 7 courses, but your approach here won't work for less than 7 courses... to make it work for a variable amount of courses you are going to need to use arrays, so you should read up on them. So instead of having credits1, credits2, etc., you would have something like:
float credits[7];

Then you can ask at the start of your program how many courses the person wants to enter.

Also, I would recommend learning a bit about functions - you have a lot of repeated code which can be shortened a lot!

Thanks! But I am still a novice......so can you show me how to use repeated function like 'while' , and 'do...while'?......and how to use 'double' and '#define' for my GPA calculator?....Actually I still not understand how to declare the 'total' ,'grade1...' and 'credits'...I always got an error.....

Try working through the tutorial on the site (http://www.cplusplus.com/doc/tutorial/) - it introduces the basic concepts you need, and should answer your questions.

i got 8 errors, can you fix and simplify it? ....

Variable names cannot have spaces in them like "Total GPA"... you can use Total_GPA instead.

Also you are using the grade variables incorrectly. You want grade1 to correspond to credit1, grade2 to correspond to credit2, and so on. So, in your if/elseif structures, you should be using grade1 = ... in the first set of if/elseif, then grade2= ... in the second set of if/elseif, etc.

Please, help me, I don't know where I made a mistake, my CGPA calculator works only if calculate for 1 sem, but when I tried to calculate CGPA with another sem., my CGPA calculator made an error in calculations.....

Um, this is a terrible coding standard:

		}	tgpa=tcg / tch;

	}		cgpa=tcgpa / sem;


I'm also not sure your calculation is correct.
Pis (9)
Ha...ha...agreed...but it still works for 1 sem only, my problem only if I add with another sem....
jsmith (5804)
So is the fact that the indentation level of your code does not match at all the actual flow of execution? Are the bottom-most three lines of code supposed to be in the inner for-loop or the outer for-loop? As it is, two of those lines are in the outer for-loop and the last line is in neither.
Pis (9)
I confused with my own code.......please help me..

GPA = [Total of (grade points x credit hours) for that semester] /
[Total of credit hours for that semester]



CGPA = [Total of (grade points x credit hours) for whole program] /
[Total of credit hours for whole program]
