Array[0]! What am I missing? Thanks :)

[mi011]

The output should be like this:
Grade 1: 90
Grade 2: 86
Grade 3: 95
Grade 4: 76
Grade 5: 92
Grade 6: 83
Grade 7: 100
Grade 8: 87
Grade 9: 91
Grade 10: -1
Average Grade: 88%
/******************************************************************

Did you receive any complier error?

Please try changing the line "int average[SIZE];" to "int average;" and see if it works.

This should be moved the Beginners board.

Post your code in code tags.
What exactly is your issue?
Average should not be an array.

[mi011]

This is my out put!
The output should be like this:
Grade 1: 90
Grade 2: 86
Grade 3: 95
Grade 4: 76
Grade 5: 92
Grade 6: 83
Grade 7: 100
Grade 8: 87
Grade 9: 91
Grade 10: 1
Average Grade: 89%

I don't how can I make it -1 and average grade should be % 88. How can I do that? Thanks a lot!

[ResidentBiscuit]

This is my out put!

What? Where?

I don't how can I make it -1

Make what -1?

average grade should be % 88. How can I do that?

Look up a formula for average.

Again, average should not be array. Your code shouldn't even compile how it is.

[aquavillan]

Have you corrected the line I mentioned earlier?

Did the code compile properly and did the program and output display?

If they did, please post the code that compiles. Maybe we will be able to see the problem that why you couldn't input a value of (-1) if you do.

[mi011]

Yes, I did change that and I think I'm very close. I came up with this loop but there is something need to be fixed. My output needs to be like that Exp: Average Grade: 88%\n

This is my code so far:
int getGrades()
{
const int SIZE = 10;
int grades[SIZE];
int average = 0;


for (int i = 0; i < SIZE; i++)
// Fill the list
{
cout << "Grade " << i + 1 << ": ";
cin >> grades[i];

average += grades[i];
if (grades >= 0)
average++;
else
return -1;
}

Thanks you so much guys your advice has been very helpful!

[aquavillan]

You should try changing the line "if(grades >= 0)" to "if(grades[i] >= 0)".

Additionally, what is "Exp"? What are you going to do if some certain grade happens to be (-1)?

[mi011]

This is so far what I got for the output. The Exp is the right output. So when I run my program through textBed it gives me the result below. I'm very close but I still need an advice.

int main()
{

getGrades();
getAverage();

return 0;
}


int getGrades()
{
int grades[10];

for (int i = 1; i <= 10; i++)
{
cout << "Grade " << i << ": "; //prompts user for grades
cin >> grades[i]; // adds values to array
}
}



int getAverage()
{
int grades[10];
int average;
int sum = 0;
int count = 0;

cout << "Average Grade: " << average
<< "%"
<< endl;

for (int i = 0; i <= 10; i++)
{
if (grades[i] > 0)
sum += grades[i];
}
average = (count / 10);
if (average == 0)
count++;
return -1;
}

Thank you so MUCH I got it :)
