}

In this program , the creat record function, returns the age time and gender of every runner. The main fuction reads lines of text from a file, as the data is returned from the data-extractin function, the results are supposed to be added to an array of different structs , arrayed by age. This array shd be of type age-record tight?
Am I declaring the arrays right? I don't think I am since I get an error message:
missising ; before identifier females ...and males.

Also once I get these numbers, how do I compute the standard deviation of their times... for all the ages? ..Go through the array twice... making sure that there is valid data(N>=2)?

In the end I'll print the age, gender , mean and standard deviation to the screen.
