Thread: Structures, files, and array help

Code:

#include <stdio.h>

typedef  struct  cars {
                                          char  make [ 20 ] ;
                                          char  model [ 20 ] ;
                                          char  color  [ 15 ] ;
                                          int  year ;
                                          double price ;
                                      }  cars ; 




//Provide the prototype for your PCFs below:




int main (void)
{
    //Local variables declared... add additional variables as required
    cars  inventory [ 25 ] ;


     //1. Open the cars.dat file in the read mode and confirm
    //     you have properly opened the file.




     //2. Read the entire contents of the cars.dat file into the
     //    inventory array.    




     //3. Close the cars.dat file




     //4. Call function_1( ), which will process the contents of the
     //    inventory array by sorting the inventory array to place all the cars
     //     in ascending order according to their price.




    //5. Call function_2( ), which will save (write) the sorted inventory
    //    array to a file named output.dat
 


    //6. Terminate
    return 0 ;
}


//Provide the definition for your PCFs below:

I can't figure out how to populate the array with the data in the data file. Above is what I have so far. Below is what the data file looks like.

You really need to show some actual effort to solve the problem.

Start by opening the file and checking that the file opened correctly.

You have all the basic steps listed, now you need to try to implement those items.
