What type functions do I need to use in c++?

Question

I learning c++ new programmes I have barcode and price of the item. I need to make project when the users put a barcode the price will come on total. Examples I made like this
Int barcode[10];
Barcode[0]= 0121;
Double price[10];
Price[0]=6.20;
Total=0;
Then I done for loop
For( int i = 0; i<10;i++
{
Cout<<enter barcode>>endl;
Cin>>barcode[i] ;

}
I can type the barcode but it doest refers to price
I can only type the barcode but doesn't refer to price.
I want the result is when the users enter barcode many time
0121
0121
Total should be
6.20
6.20
=
Total =12.40
I need help please for this to learn

Answer 1

It seems that you are taking in input and storing it in barcode[i].
Sorry if i am wrong as i dont know much about c++.

However, try storing the input in a variable, say 'barIn' and using if-else check which barcode it refers to.
This way using that barcode's index you can print the price.
