Goodmorning,
My code is not working in C++. It says: “function definition is not allowed here”.
This is the code:
#include<iostream>
#include<stdlib.h>
#include<string>
#include<istream>
#include<pthread.h>
using namespace std;
struct user_choice{
int number;
int prize[3];
string name;
}product;
struct customer_order{
int customer_id;
string status;
}customer[4];
void Menu(){
cout << "" << endl;
cout << "Main Menu" << endl;
cout << "Choose one of the options below:" << endl;
cout << "1.Choose product" << endl;
cout << "2.View order form" << endl;
cout << "3.Check order status" << endl; //mutex becuase only one person can check at a time
cout << "4.Exit" << endl;
}
void choose_product(){
cout << "" << endl;
cout << "What kind of product are you looking for? Shoes, tracksuit or shinguards?" << endl;
cout << "" << endl;
int kind_of_product;
cin >> kind_of_product;
int shoes = 0;
if (kind_of_product == shoes){
cout << "We have the new nike collection, Do you want to order them?" << endl;
string order;
cin >> order;
if (order == "yes"){
cout<< "Thank you for ordering the shoes!" << endl;
}
int tracksuit = 0;
if (kind_of_product == tracksuit){
cout << "We only have size S, do you want to order it?" << endl;
string order;
cin >> order;
if (order == "yes"){
cout<< "Thank you for ordering the tracksuit!" << endl;
}
int shinguards = 0;
if (kind_of_product == shinguards){
cout << "We only have a few left. Would you like to order it?" << endl;
string order;
cin >> order;
if (order == "yes"){
cout<< "Thank you for ordering the shinguards!" << endl;
}
}
else{
cout << "That is not an option." << endl;
}
}
void place_order(){
cout << "Write down your name:" << endl;
string name;
cin >> name;
product.name = name;
cout << "We accepted your order. We will send your product as soon as possible!" << endl;
cout << "You can check your order status in Main Menu." << endl;
}
void order_form(){
string shoes;
string tracksuit;
string shinguards;
product.prize[shoes]=69,95;
product.prize[tracksuit]=55;
product.prize[shinguards]=15;
if (kind_of_product == shoes){

}
if (kind_of_product == tracksuit){
cout << "" << endl;
cout << "You ordered the tracksuit" << endl;
cout << "Prize to pay: " << product.prize[kind_of_product] << " Euro" << endl;
}
if (kind_of_product == shinguards){
cout << "" << endl;
cout << "You ordered the shinguards" << endl;
cout << "Prize to pay: " << product.prize[kind_of_product] << " Euro" << endl;
}
}
pthread_t request[4];
pthread_mutex_t locker;
// function to check status by id
void check_status(int id){
for(int a=0;a<=3;a++){
if(customer[a].customer_id == id){
cout << customer[a].status << endl;
}
}
}
// demand of checking the status
void *demand(void* arg){
pthread_mutex_lock(&locker);
cout << " " << endl;
cout << "Hello, I'm customer number " << pthread_self() - 1 << endl;
int my_id = (customer[pthread_self()-2].customer_id);
cout << "My ID is:" << my_id << endl;
check_status(my_id);
cout << " " << endl;
pthread_mutex_unlock(&locker);
}
int main() {
// Print Menu
cout << "Welcome to the best online Soccer Store of the world!"<< endl;
Menu();
cin >> answer;
int kind_of_product;
switch(answer){
case 1:
choose_product();
break;
case 2:
order_form();
break;
case 3: // simulation for checking status for 4 customers at the same time
// creating 4 customers
customer[0].customer_id = 999;
customer[0].status = "Product has been sent";
customer[1].customer_id = 888;
customer[1].status = "We are preparing your shipping ";
customer[2].customer_id = 555;
customer[2].status = "Product has been sent";
customer[3].customer_id = 111;
customer[3].status = "We are preparing your shipping ";
//creating mutex (locker so as not to mix the lines)
pthread_mutex_init(&locker, NULL);
// creating threads (customers demands of checking status)
for(int i=0;i<=3;i++){
pthread_create(&request[i],NULL,&demand,NULL);
}
pthread_join(request[0],NULL);
pthread_join(request[1],NULL);
pthread_join(request[2],NULL);
pthread_join(request[3],NULL);
pthread_mutex_destroy(&locker);
break;
case 4:
// EXIT
break;
}
}
}
}
Is there anyone who can help me out?
Best regards,
Abel
