[問題] c++ 寫數列 1.1.2.3.5.8
對數列 An 已知
A0 = 1
A1 = 1
A2 = A1 + A0
A3 = A2 + A1
A4 = A3 + A2
請問要如何寫出 An ?
謝謝~

------------------------------------------------------------------------
int n ,c;
cin>>n;
while (n >= 0){
if ( n == 0 or n == 1){
cout << "1" ;
}
else{
for ( int i = 1 ; i <= n ; i++ ){
int a , b ;
a = i ;
b = a + i ;
c = a + b ;
}
cout << c << endl;
}
break;
}
------------------------以上我的想法---------------------------------------
