I have made a "computer". My conctructor looks like this:
PC::PC()
{
cout << "Would you like to turn the pc on? type y for yes." << endl;
a = getchar();
while (a != 'y')
{
cout << "If you dont turn it on, then nothing will happen. Loser." << endl;
a = getchar();
}
}
Then if you press y you will be sent to the next step which is the function PC::pcOn which looks like this:
void PC::pcOn()
{
for (auto i = 0; i < 3; i++)
{
cout << "----------------------------------------" << endl;
}
cout << "--------- What is your name? -----------" << endl;
changeName();
for (auto i = 0; i < 3; i++)
{
cout << "----------------------------------------" << endl;
}
for (auto i = 0; i < 5; i++)
{
cout << "**" << endl;
Sleep(100);
}
cout << "Welcome " << name << " to the future of computing." << endl << endl;
cout << "This computer program can do a lot of things for you" << endl << "it is a good calculator, try to type \"calculater\"" << endl;
}
However when i have the while loop in the contructor to get the y to go on, the changeName(); wont work, but if i remove that, the changeName function works just fine, and it takes my input just fine.
The code for the changeName() looks like this:
void PC::changeName()
{
string _name;
getline(cin, _name);
name = _name;
}
I have tried using the Visual Studio's debugger to see why i wont call it correctly, but alas to no hope. The weird thing is, that the function works fine if the while loop in the constructor is not there.
It is because in getline(cin, _name)
, it always inputs the "/n" character as it is feeded when you type enter.
To correct it, put a getchar();
void PC::changeName()
{
string _name;
getchar();
getline(cin, _name);
name = _name;
}
