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); C Programming Interview / Viva Q&A List https://technotip.com/6378/c-programming-interview-viva-qa-list/ C Programming: Beginner To Advance To Expert https://technotip.com/6086/c-programming-beginner-to-advance-to-expert/ ... https://www.youtube.com/watch?v=2CU6uSjyndA

https://technotip.com/7841/c-program-to-print-n-co-prime-numbers/ Lets write a C program to print N co-prime or relative prime numbers. N being the user entered limit for printing the co-prime number pairs. Co-Prime numbers / Relative Prime Numbers: Two numbers are said to be co-prime or relative prime numbers if they do not have a common factor other than 1. OR Two numbers whose Greatest Common Divisor(GCD) is 1 are known as Co-Prime or Relative Prime Numbers. Note: User entered numbers(to check for co-prime) do not require to be prime numbers. Factors of a number: All the numbers which perfectly divide a given number are called as Factors of that number. Expected Result If user inputs limit = 5 Output 1. ( 2, 3 ) are co-prime numbers. 2. ( 3, 4 ) are co-prime numbers. 3. ( 2, 5 ) are co-prime numbers. 4. ( 3, 5 ) are co-prime numbers. 5. ( 4, 5 ) are co-prime numbers.
