Answer 1

Without full code, it is tough to understand what you said.
This code saying in first for loop you are adding to price to total if itemcode and barcode same.
After that you want to exit condition.?
For that you can add like
char c;
cin>>c;
if(c=='f')
return; //or break; if you want come out of loop;
After that You are taking input for to withdraw, if cash < total deduct from total else print msg last one and break the loop...

Sentence properly or try use google translate if it is hard for you. Not understandable it is for me..
And you are not using any function any where..
Am not telling you to do anything, You tell me what is your required inputs and output.. What problem you are geeting?

Shofi Uddin
cout<<"the total price is"<<total<<endl;
do
{
cout<<"cash please:"<<endl;
cin>>cash;
if(cash>=total)
{
rest=cash-total;
break;
}
else {
cout<<"you need more cash"<<endl;
}
}while(true);

this loop works until you give needed total.. is it what you want?

Answer 4

Where are you adding cash? What you are expecting by this code actually? Can you explain..

Answer 5

for (int i=0;number;i++){
for (int j=0;j<5;j++){
if(itemcode[i]==barcode[j]){
total+=price[j];
}
}
}
//here will shows the price of the totall of the user put the code //

//how do i do if the user put "f" to terminate the operation the show the total value of it ..//

cout <<"the total price is:"
<<total<<"dollar"<<endl;

cout <<"cash";
cin >>cash ;

for(int m=0;m< total;m++){
if(cash>=total){
cout <<"need more money"<<endl;
}
}
//if i need more money do i need to use others loop function..this the loop function to use if cash give less the total will show the message need more money//
cout <<"change"<< cash- total <<"\n\n";

The problem I am getting is from the total I get the rest
Example if the total is 40 and the user put 50 the give the rest 10
But what I want is if the total is 40
And the users put 30 will get a message need for money and the users can put more until is get the total

Answer 10

Yes thank you but u know u did rest=cash-total
Rest do I need to declare as double
Because
I already declare cash and total

Answer 11

Rest is the remaining amount you need to give back to the user. So if you want your program to tell that and to update , then use it other wise use like
cash=cash-total ;
Use it according to your requirement. I cant say because i don't know about your full code. How can i say?
