In C language: (text files provided)

Description: This function should open and read the given input file which contains information about all rental cars. It should store each car's data in an element of the given array arr, and return the number of cars it read from the file. Notice that the file contains extra information which you should just skip/ignore (using * option in fscanf) Obviously the value of member is_available should be initialized to 1 for all elements of array arr.

Function:

int readCarsInfo(char *filename, CarInfo arr[]) { int n = 0;

// ...

return n; }
