We will extend the Code from the previous post
https://steemit.com/programming/@drifter1/programming-or-c-beginner-codes
Code:
We will extend the last one adding Arrays that will save the vehicle informations and print them all out.
All the values will be randomized and so the program doesn't need any user input. Also, we now don't have an driver_id but we will have a numberplate for each vehicle and the type will be also random. Last but not least we will count how many of each vehicletype paid with a specific payment type (like how many Cars paid only with Cash).
#include //for input and output functions
#include //rand() function
#define N 100 //making the value tweakable so that the programm will terminate after N=100 vehicles
