cin and getline skipping input

Question

earlier i posted a question about cin skipping input  and I got results to flush  and use istringstream  but now I tried every possible solution but none of them work   here is my code   void createNewCustomer          string name  address       cout  lt  lt   Creating a new customer      lt  lt  endl      cout  lt  lt   Enter the customer s name     getline cin  name       cout  lt  lt   Enter the customer s address     getline cin  address        Customer c name  address  0       CustomerDB  addCustomer c        cout  lt  lt  endl      but I m still getting the same thing  skipping input  and when it does take input  it takes them and stores in name empty nothing  and in address it takes what i wrote in name but from the 2nd letter to the end  what is wrong with my code   I tried the cin ignore    cin get    and cin clear   all of them together and alone  none of them worked  EDIT   main method in main cpp invokes mainMenu   only  void mainMenu          char choice       do           system  cls            mainMenuDisplay            cin  gt  gt  choice          system  cls             switch  choice                case  1                   customerMenu                    break               case  2                   dvdMenu                    break               case  3                   receiptMenu                    break               case  4                   outro                    break               default                  cout  lt  lt    a                      cin ignore            cin get          while  choice     4        i will choose 1 for the customer example  this is customerMenu    void customerMenu          char choice       do           system  cls            manageCustomerMenu            cin  gt  gt  choice          system  cls             switch  choice                case  1                   createNewCustomer                    break               case  2                   deleteCustomer                    break               case  3                   updateCustomerStatus                    break               case  4                   viewCustomersList                    break               case  5                   mainMenu                    break               default                  cout  lt  lt    a                      cin ignore            cin get          while  choice     5        I choose 1 again to create a new customer object  which will now go to the MainFunctions cpp which will invoke the function createNewCustomer   which is the first one   void createNewCustomer          string name  address       cout  lt  lt   Creating a new customer      lt  lt  endl      cout  lt  lt   Enter the customer s name     cin getline name 256       cout  lt  lt   Enter the customer s address     cin getline address 256        Customer c name  address  0       CustomerDB  addCustomer c        cout  lt  lt  endl

The structure of your menu code is the issue   cin  gt  gt  choice       new line character is left in the stream   switch                   We enter the handlers    n  still in the stream     cin ignore         Put this right after cin  gt  gt  choice  before you go on                    getting input with getline

Here  the   n  left by cin  is creating issues   do       system  cls        manageCustomerMenu        cin  gt  gt  choice                 This cin is leaving a trailing  n     system  cls         switch  choice            case  1               createNewCustomer                break    This  n is being consumed by next getline in createNewCustomer    You should use getline instead -  do       system  cls        manageCustomerMenu        getline cin  choice                     system  cls         switch  choice            case  1               createNewCustomer                break    I think this would resolve the issue

I faced this issue  and resolved this issue using getchar   to catch the    n   new char

If you re using getline after cin  gt  gt  something  you need to flush the newline out of the buffer in between   My personal favourite for this if no characters past the newline are needed is cin sync    However  it is implementation defined  so it might not work the same way as it does for me  For something solid  use cin ignore    Or make use of std  ws to remove leading whitespace if desirable   int a   cin  gt  gt  a  cin ignore  std  numeric limits lt std  streamsize gt   max      n       discard characters until newline is found    my method  cin sync      discard unread characters  string s  getline  cin  s     newline is gone  so this executes    other method  getline cin  gt  gt  ws  s     remove all leading whitespace
