# Programming | C Beginner Arrays

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 <stdio.h> //for input and output functions

#include <stdlib.h> //rand() function

#define N 100 //making the value tweakable so that the programm will terminate after N=100 vehicles

int main(){

```
int i=0; //vehicle counter variable
int vehicles=0, cars=0, bikes=0, trucks=0; //counter variables for each type and all together
int card=0, cash=0, both=0; //counter variables for each payment type
int card_b=0, cash_b=0, both_b=0; // counter for payment type if Bike
int card_c=0, cash_c=0, both_c=0; // if Car
int card_t=0, cash_t=0, both_t=0; // if Truck
int plate; //plate of current vehicle
int plates[N]; //plate array of all vehicles
int fee; //fee the current Vehicle has to pay
int balance_bef[N], balance_aft[N]; //array for balance before and after payment of fee
int total, total_cars, total_bikes, total_trucks; //total payment for all together and each type at it's own
int total_card=0, total_cash=0; //total payment for each payment type
int fees[N], cash_p[N], card_p[N]; //array of fees, payment with cash and payment with card for each vehicle
int r; //random number for generating random type
char type; //we get the value randomly with 'r'
char types[N]; //type array of all vehicles
char p_types[N]; //payment type array of all vehicles
float avg; //floating point number for the average
srand(time(NULL)); //rand() function seed set to current time, so that each time runned the program gives other values
while(i<N){ //run until i equals N, so for N vehicles
//plate will be random number between 10000...90000
plate = 10000 + rand()%(90000 - 10000 + 1); //random_value = start + rand()%(end - start +1)
plates[i] = plate; //save the current plate to the array
//balance will be random between 0...10

vehicles++;
//payment

balance_aft[i] = balance_bef[i] - fee; //new balance
cash_p[i] = 0; //nothing paid in cash
card_p[i] = fee; //fee paid with card
card++; //counter for card payment goes 1 up
total_card += fee; //total payment from card goes up by fee
p_types[i] = 'c'; //card payment type
}
else if( balance_bef[i] == 0){ //pay with cash
balance_aft[i] = 0; //balance remains 0
cash_p[i] = fee; //fee paid with cash
card_p[i] = 0; //nothing paid with card
cash++; //cash counter goes 1 up
total_cash += fee; //total payment from cash goes up by fee

}
else{ //pay with both
balance_aft[i] = 0; //new balance is 0
cash_p[i] = fee - balance_bef[i];
card_p[i] = balance_bef[i];
both++; //counter for both goes up by 1
total_cash += cash_p[i] ; //total payment from cash goes up by cash paid
total_card += balance_bef[i]; //total payment from card goes up by balance

}
i++; //counter goes up by one to go to the next vehicle
```
