Я делаю интерфейс ATM на C++ для школьного проекта моего друга. Как я могу изменить PIN-код в звездочки «*»? Постскриптум коды вывода находятся в MAIN. спасибо: D

Answer 1

Вы можете использовать getch() так:

int i=1; 
cout<<"\n\n\n\t\t\t\tEnter your PIN: "; 
while((p=getch()) != '\n' && p==i) { 
    i++; 
    cout<<"*"; 
} 
if(i==5) 
    transaction();    
else {   
    clrscr();   
    cout<<"\n\n\n\t\t\t\t Wrong PIN!";   
    cout<<"\n\n\t\t\t Please get your card.";   
} 

Или так:

int i=0,pin[4]={0}; 
cout<<"\n\n\n\t\t\t\tEnter your PIN: "; 
while((pin[i]=getch()) != '\n' && i<4) { 
    i++; 
    cout<<"*"; 
} 
if(pin[0]==1 && pin[1]==2 && pin[2]==3 && pin[3]==4) 
    transaction();    
else {   
    clrscr();   
    cout<<"\n\n\n\t\t\t\t Wrong PIN!";   
    cout<<"\n\n\t\t\t Please get your card.";   
}
