Can anyone help me with this code in C ?

2. Write a program to calculate the arithmetic mean, the geometric mean, and the harmonic mean for a set of non- zero numbers. Ask the user to enter values for the numbers between 0 and 10 and enter -99 when they are done. Within the sentinel loop, calculate the required sums and product. Use doubles for the variables. arithmetic mean 2 geometric_mean -xx *.x harmonic mean - Calculate the means after exiting from the loop and print using 3 decimal digits. Test with 7.3, 3.0, 9.2, 4.6, 5..5
