Question

This is my main program,

int main () {

    string command;
    cin>>command;

    if(command == "keyword")
    {
        string str, str2, str3, str4;

        cout << "Enter first name: ";
        getline (cin,str);

        cout << "Enter last name: ";
        getline (cin,str2);

        cout << "Enter age: ";
        getline (cin,str3);

        cout<<"Enter country: ";
        getline (cin,str4);

        cout << "Thank you, " << str <<" "<<str2 <<" "<<str3<<" "<<str4<< ".\n";
    }
}

When keyword is entered, the program immediately outputs :

Enter first name: Enter last name:

completely bypassing the ability to enter the first name.

Answer 1

string command;
cin>>command;

after this just eat the end of the line

string restOfLine;
getline(cin, restOfLine);

Otherwise the ‘\n’ in the line where you input command is not consumed and the next readline reads just it. HTH
