heres code I have done so far, I am mostly confused on how to sort the array from the file and store the array.
Code:/* Algorithm: 1. In the main ( ), open the cars.dat file in the read mode and confirm you have properly opened the file. 2. In the main ( ), read the entire contents of the cars.dat file into the inventory array. 3. In the main ( ), 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 ALGORITHM FOR function_1( ): 1. */ #include <stdio.h> #include <stdlib.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: void function_1(cars inventory[], int size); int main (void) { //Local variables declared... add additional variables as required cars inventory [ 25 ] ; int size = 0; FILE *input; const char *inputfile = "cars.dat"; //1. Open the cars.dat file in the read mode and confirm // you have properly opened the file. input = fopen(inputfile, "r"); //2. Read the entire contents of the cars.dat file into the // inventory array. while ((fscanf(input, "%s%s%s%d%lf", &inventory[size].make, &inventory[size].model, &inventory[size].color, &inventory[size].year, &inventory[size].price ) && (size < 25) ) size++; //3. Close the cars.dat file fclose(input); //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. function_1(inventory, size); //5. Call function_2( ), which will save (write) the sorted inventory // array to a file named output.dat //6. Terminate return 0 ; }
