- It is possible to compile C programs with it, but you'll see some issues and incompleteness. Moreover, it lacks many features familiar with more modern IDEs. So, new programmers might find them confusing or rudimentary, or even not suitable for new-age C programming. If you work in a programming team, DEV-C is not the best option.

Standard deviation is a measure of spread of numbers in a set of data from its mean value. Use our online standard deviation calculator to find the mean, variance and arithmetic standard deviation of the given numbers.
Standard deviation is a measure of spread of numbers in a set of data from its mean value. Use our online standard deviation calculator to find the mean, variance and arithmetic standard deviation of the given numbers.
Formula :
Mean :Mean = Sum of X values / N(Number of Values)Variance : Variance = s2
Sample Standard Deviation :
Population SD :
In statistics, Standard Deviation (SD) is the measure of 'Dispersement' of the numbers in a set of data from its mean value. This is represented using the symbol σ (sigma). The formula for the Standard Deviation is square root of the Variance. Here is a free online arithmetic standard deviation calculator to help you solve your statistical questions. This can also be used as a measure of variability or volatility for the given set of data. Enter the set of values in the online SD calculator to calculate the mean, standard deviation, variance and population standard deviation.
Example:
Consider a set X = {5,10,15,20,25}
Sample Standard Dev Calculator
Step 1 :
Mean = Sum of X values / N(Number of values)
= (5+10+15+20+25) / 5
= 75 / 5
= 15 Hence Mean = 15
= (5+10+15+20+25) / 5
= 75 / 5
= 15 Hence Mean = 15
Step 2 :
To find the variance,
Subtract the mean from each of the x values,
5-15 = -10
10-15 = -5
15-15 = 0
20-15 = 5
25-15 = 10
Now square all the answers you have got from subtraction.
(-10)2 = 100
(-5)2 = 25
(0)2 = 0
(5)2 = 25
(10)2 = 100
Add all the Squared numbers,
100 + 25 + 0 + 25 + 100 = 250
Divide the sum of squares by (n-1)
250 / (5-1) = 250 / 4 = 62.5
Hence Variance = 62.5
Subtract the mean from each of the x values,
5-15 = -10
10-15 = -5
15-15 = 0
20-15 = 5
25-15 = 10
Now square all the answers you have got from subtraction.
(-10)2 = 100
(-5)2 = 25
(0)2 = 0
(5)2 = 25
(10)2 = 100
Add all the Squared numbers,
100 + 25 + 0 + 25 + 100 = 250
Divide the sum of squares by (n-1)
250 / (5-1) = 250 / 4 = 62.5
Hence Variance = 62.5
Step 3 :
Find the square root of variance,
√62.5 = 7.905
Hence Standard deviation is 7.905
To find minimum and maximum SD,
Minimum SD = Mean - SD
= 15 - 7.905
= 7.094
Maximum SD = Mean + SD
=15 + 7.905
= 22.906
√62.5 = 7.905
Hence Standard deviation is 7.905
To find minimum and maximum SD,
Minimum SD = Mean - SD
= 15 - 7.905
= 7.094
Maximum SD = Mean + SD
=15 + 7.905
= 22.906
Step 4 :
To find the population SD,
Divide the sum of squares found in step 2 by n
250 / 5 = 50
Find the square root of 50, √50 = 7.07
Divide the sum of squares found in step 2 by n
250 / 5 = 50
Find the square root of 50, √50 = 7.07

I think that you should probably think about indenting your code a little, so that the various blocks are a bit easier to pick out.
Also, I think that it's generally best to have
main()
return int
rather than void
, that way you can check the return value of the program and see if everything went as expected.So, your code properly formatted, with some other little bits corrected:

Esp32 dev kit v1. @hayzam take some time and read the post from ravenous. there is plenty to be learned there.

I definitely agree with ravenous in that an organized source is always best for you or anyone else working with the code. Otherwise a very good, precise age calculator.

I think you should taken current year and current month and same day using Computer time with help of <time.h> header file because most user want program is made in such way which only gives output without more or unnessary input.
Thanks Man

these codes are wrong!!!!
My birthday is on 1997 9, and it is 2012 7 now
it says i am 15 year and 3 month old but I'm not
I have a solution for this

Assuming your system time is ok, this will calculate an aproximate of your years:
The age calculator is not quite right because it does not calculate the months correctly.
If the current month is less than the birth month then the years are shown as one too many. The months are calculated as 12 minus the birth months, which is incorrect in most instances.
The calculation should be
If (current month minus birth month) > 0 then
years = current year minus birth year
months = current month minus birth month
else
years = (current year minus birth year) - 1
months = 12 - (birth month minus current month)
If the current month is less than the birth month then the years are shown as one too many. The months are calculated as 12 minus the birth months, which is incorrect in most instances.
The calculation should be
If (current month minus birth month) > 0 then
years = current year minus birth year
months = current month minus birth month
else
years = (current year minus birth year) - 1
months = 12 - (birth month minus current month)

Rajeesh.N.Santhu, you made too many mistakes. He is not showing the months correctly. I am going to rewrite this program in Dutch, and whitout mistakes of course. :-D
Thanks for the idea. I already made a program to calculate temperature scales, I made a program which calculates the average and the sum, I made a program which is showing you random zeros and ones, I made a program which is giving random numbers, I made a mini-game where you can wed coins (beginning with 200 coins), and now I am going to rewrite a program which calculates your age.
I also made an article about a program like this.

Good day.i am requesting if you can make a code of a simple registration system please.which indicates .name.address.birthdate.age.and etc.thank you
@takuya17 - Please don't resurrect dead threads with something completely unrelated. If you want to contract a coding job you need to do so under the Jobs and resumes section in business exchange.
