Question
Here is the code i have so far, i need data to get read into the array.
Here are the complete direction
//Given the original AL Weather Station Data file design a structure for one record
//of data where one record consists of all eleven data items on one line of the data file (starting after the headers and line of dashes).
//Next, create an array of records with enough elements to hold the entire data file. Initialize the array of records by reading in all the data from the file.
//
//Write the following functions that will process the data from the array of records:
//Compute average high temperatures for any one of the three days. Date will be a parameter to the function. The user will select the day from the three available.
//Find and print weather stations that reported precipitation PRCP above a given amount on a specific day. (NOTE: the data is shown in hundredths of an inch. 13 is 0.13 inches)
//
//From your main program call the functions to:
//Compute the average TMAX for June 1
//Find and print all weather stations reporting more than 0.50 inches of precipitation on June 2

Explanation / Answer
The data1 array should be filled with the data file you have read from desktop, not with the random data. You can apply loop to get it store to the final array you have created station_A[307]. Also I am not getting why are you specifically creating the array of 307 records. You should decide the length of the array with the number of records in the file.
Hope this will be useful to you. I am attaching the part of the code to help you more.
