Problems reading values from a file and calculating the sum

[charmeda103]

i have to calculate a total amount of pounds for my program. i am getting each pound calculated but i have to add up all those pounds into one total.
the problem is one of the total pounds is not supposed to be calculated.

how do i do this I am struggling

OUTPUT:
Total weight21.5
Total weight30
Total weight50.8
Total weight12.4
Total weight42.6
Total weight31.5
Total weight22.4
Total weight71.3 this total cant be included in the total pounds

the total amount of weight has to come out to 211.2pounds
I cant figure how to get that amount. Any ideas will help!


here is the code that calculates the above:

 
totalWeight=weightOfPounds;
                outFile2<< "Total weight" << totalWeight << endl;

So ... you have a list of input values and you want to compute the sum of all these input values except for one that should be left out of the sum.

What is distinctive about the input value that doesn't go into the sum? How do you recognize which one doesn't get added in with the others? By "you", I mean you as a person -- we'll worry about how your computer program recognizes it later.

Do these input values come from typed user input, read from an input file, passed as input arguments to your function, or are they hard-coded into your program?

[charmeda103]

the input values are read in from an input file,

[whodgson]

Is it not possible to keep a running total of the 'pounds' with an expression like
sum+=pounds;
.......in a for loop?

[donbock]

the input values are read in from an input file,

OK. What is the format of the input file ... is it simply a newline-separated list of floating-point values, is it a list of "label=value" assignments, is it something else.

And most importantly, let me repeat my earlier question. How do you know which input values do NOT go into the sum?

[charmeda103]

if have of numbers written separetly in a for loop and those numbers to totaled into one sum. how would u do that;






example:

Total weight21.5
Total weight30
Total weight50.8
Total weight12.4
Total weight42.6
Total weight31.5
Total weight22.4
Total weight71.3


the total sum=211.2


these are reading in from a input file.


Anything will help please.

Make a variable for the total sum, set it to zero, and then every time you read in a number from the file, add it to the total.
Hope this helps.

[donbock]

In your other thread you said that some of the input values shouldn't go into the sum. Is that still the case or did I misunderstand?
Name of the other thread: "PLEASE Im having so much trouble with this calculation."

What step of the problem are you having trouble with?
... Can you read the input file?
... Can you extract the input values from the input file?
... Can you add the input values together into a sum?

Are you stuck and don't know how to start?
Did you write a program but it either won't compile or it doesn't do what you want?

[donbock]

Suppose all of the input values were in a global array like this:
double inputValues[10];

How would you compute the sum of all entries in the array?

the program is reading from the input file,
I started the program i added the program to the thread so you can see what im stuck on.

My program is readng each weight separtley but i want it to read in the sum of all the weights.I am trying to add the each indvidul weight I called this variable "weightOfBagsFo rPassenger" to come up with a total of 211.2. I cant include the last weight of 71.3 because that weight has been rejected.

I declared a new variable called totalSum=0;
from my program i cant determine how to add the total of the "weightOfBagsFo rPassenger"
into one sum.
does that make sense?
