Can we perform mathematical operations for dictionary values type integer in c#, and how?

Question

Like This Code

Dictionary<string, int> dictionary =new Dictionary<string, int>();

//add keys and values in the dictionary

dictionary.Add("YEM", 124);

dictionary.Add("SHA", 20);

dictionary.Add("MOH", 63);

dictionary.Add("SAL", 84);

I need to find the Percentage for each value how I can do that

Answer 1

Shafiq Mohammed Almatri ,

in python it can be done like:

dic = {"YEM": 124, "SHA": 20, "MOH": 63, "SAL": 84}
total = sum(dic.values())

the variable total holds now the sum of all values.

in the next step use a for loop, pick each value from dic and calculate the percentage by using the total

Answer 2

Shafiq Mohammed Almatri ,

we have presented you 2 code snippets that can do the requested task. the rest is basic mathematical stuff.

if you need more, please do a try and post it here if you get stuck somewhere.

Answer 3

You can perform mathematical operations on numbers. In this case the dictionary values are int, so yes, you can.
To calculate the sum of all values you can do this:
int sum = dictionary.Values.Sum();

Then you can loop over the dictionary and calculate the percentage by dividing each value by the sum.

Answer 4

Well... If we want to calculate the tax for each value
Like This
If YEM =124 , tax=5%
Then The tax will be
124*5/100 =6.2
How I can return the value of YEM after take the tax
YEM with new value=124-6.2=117.8
