C ++从“ else”语句继续

Question

I'm writing a little c++ console program to improve my programming and to begin a portfolio. My question is:

How do I continue my story after the else statement?

Part of the code I have is:

else {
    cout << "That's not an answer mate!" << endl;
}

How do I make the program NOT exit, but ask for a new input from the user?

Thanks in advance!

Answer 1

You wrap the qustioning code in a while and keep asking until the "correct" answer is given:

bool error;
do {
  error = false;
  //some code here..
  //if statement to check..
  else
  {
    cout << "That's not an answer mate!" << endl;
    error = true;
  }
}while(error);

Answer 2

You can use goto statement example:

Condition1: cout<<"Enter age: ";
cin>>age;

if (age>18){
cout<<"Welcome"<<endl;
//same code...
}
else{
goto Condition1;
}

this is the same method as using loops
