A Program using an array that culculates the sum and average of the five input values?

The easiest way is to add a field, name it attendance or something and assign a value of one. Then sum column a / sum column b for average.

Mean=Average =(Sum of data values)/(number of data in set)
Sum of data values =6+6+11+12=35
Number of data =4
Average =Mean =35/4=8.75

That appears to be an intermediate question in a programming class. Best read the book, the answer is not what is important the process of getting the answer is what you are trying to learn.

You could do this by creating two arrays as such:
int firstArray[5]; int secondArray[5]
and then the sum variable:
int sum = 0;
then you could do a for loop to find the sum of the second array:

Hi.

I suggest creating an Array of Cards (cardOne,cardTwo,etc. to five)

If you can enter them in one at a time, after declaring the array, assign the values to the array.

cin < cardOne; (Psuedo code by the way, hope you don't mind)

Afterwards, you'll have an array with 5 cards.

Declare what full houses, flushes, etc would require.
Use an if statement (If you don't mind lots of code) to compare the entered Array against possible hands.

I didn't necessarily give you any specific C++ code. However, if you Google C++ user input, you should find plenty of commands that may help you.

Good Luck

(And not sure about Linear search to be honest, you can use a Linear search, but if you did it the way I explained, you just have to compare hand to a series of conditionals.)

hi, here is the program #include<stdio.h> #include<conio.h> void main() { int class[30],i; float sum=0,avg=0; printf("enter marks"); for(i-0;i<30;i++) scanf("%d",&class[i]); for(i-0;i<30;i++)
sum+=class[i]; avg=sum/30; printf("%f",avg); getch(); }

for int i=0; i< array.count; i++
{
sum+= array[i];

}

average = sum/5

Hi Griffnz,

Your "known Y's" or 'values' are in Column B. This is the first array in the Trend formula.

Your "known X's" or 'months' are in Column A. This is the second array in the trend formula.

The trend formula is supposed to give you a projection of what the rest of the values in Column B will be over the next few months (usually continuing cells in Column A). The cells you want these values to show up in represent the third array in the formula.

Thus, your formula should look more like: '=trend(B3:B14,A3:A14,A15:A18)'

However, your formula is leaving out The values in B and adding values from C - -- but there ARE no values in C. Apparently, C is where you want the values to appear. In that case, the C array would be the third array in your formula. This would look more like '=trend(B3:B14,A3:A14,C3:C14)

If this doesn't make sense, let me know.

Q.2#  Dim n, sum as Double
Dim i as Integer
n=100
sum=0

for i=1 to n
sum=sum+1/n
next i

Q.3#  Dim sum as Double
sum=0
for i=1 to 99
if i%2 <> 0 then sum=sum+i end if
next i
