Calculate Sum, Average, Variance and Standard Deviation: C Program

https://technotip.com/7955/calculate-sum-average-variance-and-standard-deviation-c-program/

Write a function that receives 5 integers and returns the sum, average and standard deviation of these numbers. Call this function from main() and print the results in main().

Very Important Note: Any address preceded by a * (Indirection operator) will fetch the value present at that address.

Using below formula we calculate sum, average/mean, variance and standard deviation:

*sum = a + b + c + d + e; *avg = *sum / 5.0;

*variance = ( (a – *avg) x (a – *avg) + (b – *avg) x (b – *avg) + (c – *avg) x (c – *avg) + (d – *avg) x (d – *avg) + (e – *avg) x (e – *avg) ) / 5.0;

*standard_deviation = sqrt(*variance);
