when I'm executing this program, it works fine just for one option, but if I try to choose an other option when executing, it will throw an error in this line:
cout << "The available quantity is: " << *(it->second.find(disp)) << endl;
here's my program:
void avail_art(void)
{
char c,con;
int quantity,disp=MAX;
bool b = true;
map<string, unordered_set<int>>m{
{"Mouse",{120,disp}},
{"Keyboard",{75,disp}},
{"Monitor",{750,disp}},
{"GPU",{1200,disp}},
{"CPU",{1000,disp}}
};
auto it = m.find("CPU");
cout << "M - for mouse." << endl;
cout << "K - for keyboard." << endl;
cout << "R - for monitor." << endl;
cout << "G - for GPU." << endl;
cout << "C - for CPU." << endl;

My C++ program wants the user to choose a test option. Option A wants the user to login their id, then they will proceed to take the test. Option B gives the user the results of the taken test. Finally, Option C will make the user quit.
I am trying to get the function getStatistics() to display whether the question that what the user answered is right or wrong, display the user answers and the correct answer.

The problem is that getStatistics() is just getting the last input from test(), for example if you input the right answer for question 1 and input the right answer question 3, when you run the getStatistics()it only remembers the last input from test() and thus deem the right answer for question 1 incorrect. Is there anyway for the getStatistics() to remember all the user answers for all the questions from test(), instead of just getting what is last answered.Thank you.

I am trying to build a menu on console on C++ with CodeBlock. Is for a course.
I would like to validate garbage enter by the user. For example, the user have to enter a number. If he enters a wrong number, no problem, the program work and continue. But if He enters a letter or some garbage, the program start on infinite loop.
I cannot use system(PAUSE) because I am programming on Linux.
I tried some code like cin.get() or do while with cin.get() but no result.
Here is my code :
#include <iostream>
using namespace std;
void showMenu()
{
cout << "---------------MENU --------------" << endl;
cout << "1- Check balance :" << endl;
cout << "2- Check deposit :" << endl;
cout << "3- Withdraw:" << endl;
cout << "4- Exit" << endl;
cout << "--------------------------------" << endl;
}
int main()
{
int option;
double balance = 500;
do
{
showMenu();
cout << "Option: ";
cin >> option;
cout << "\033[2J\033[1;1H";
switch(option)
{
case 1:
cout << "Balance is: " << balance << " $" << endl;
break;
case 2:
cout << "Deposit amount: " << endl;
double depositAmount;
cin >> depositAmount;
balance += depositAmount;
break;
case 3:
cout << "Withdraw amount: " << endl;
double withdrawAmount;
cin >> withdrawAmount;
if (withdrawAmount <= balance) {
balance -= withdrawAmount;
}
else {
cout << "Not enough money" << endl;
}
break;
default:
cout << "Your choice is invalid ";
do {
cout << '\n' << "Press the Enter key to continue.";
}while (cin.get() != '\n');
}
} while(option != 4);
return 0;
}
Do you have an idea how can I validate easily the garbage enter by the user ?
Thank you for your Help
It works with the code on default part : cin.clear and cin.ignore(). This last one is important. Thank you to user4581301

so I have a school project where I'm trying to create a bank account. So I have an array of class customer containing the customer name etc, this customer can have multiple accounts, so I have created an array of class accounts inside of customer. My problem is, I can't call a getter function inside of the account array, I have tried using customerArray[curr_id]->accountArray[curr_acc_num]->get_balance() however I am getting an error telling my that it is unaccessable.

I am working on an assignment. The problem I am having is every time I try to run my program to see what it displays, nothing shows up on the command prompt. However, if I press any key and then enter, the program starts looping uncontrollably. The program doesn't even display the initial cout message, just a blinking "_". Thanks
