一、代码
1 #include <iostream> 2 using namespace std; 3 void fun(int n) 4 { 5 int a=1; 6 int b=1; 7 int sum=0; 8 if(n<2) 9 cout<<a<<endl; 10 if(n==2) 11 cout<<a<<" "<<b<<" "<<endl; 12 13 else 14 { 15 cout<<a<<" "<<b<<" "; 16 for(int i=1;i<=n-2;i++) 17 { 18 sum=a+b; 19 a=b; 20 b=sum; 21 if(i%5==0) 22 cout<<endl; 23 cout<<sum<<" "; 24 } 25 } 26 } 27 void main() 28 { 29 cout<<"请输入前N位数:"<<endl; 30 int m; 31 cin>>m; 32 fun(m); 33 cout<<endl; 34 }
