Why the computer stop working when I type the number and press enter

Question

#include <iostream>
using namespace std;

int main(){

int barcode[5];

barcode [0]=0120001;
barcode [1]=0121002;
barcode [2]=0122003;
barcode [3]=0122004;
barcode [4]=0122005;

double price[5];

price [0]=2.50;
price [1]=4.50;
price [2]=7.35;
price [3]=8.50;
price [4]=12.75;
Char= 'F';
double total=0;
int itemnum ;
cin >> itemnum ;
int item[n];

for(int i=0;i<itemnum;i++){
cin>> " barcode (type F to finish)" itemnum[i];
}

for(int i=0;i<n;i++){
for(int j=0;j<5;j++){
if(itemnum [i] == barcode [j]){
total+=price[j];

}
}
}

cout << "The total price of the items is: " << total << endl;

Char= 'F';
return 0;
}

Hellow, welcome to sololearn!

I don't understand C++ but it might be due to an infinite loop.

When this happens make sure to try and stop the program with task manager (if ur using windows).
You can access task manager by pressing ctrl + shift + esc

This problem usually affects memory so if you unusually have a high memory usage on task manager that might be the problem

Note- next time try and put your code in a sololearn file (with the plus sign). This will make it easier to read and can get you more responses

Hope this helps and have a good one, good luck :)
