从第三个输出中可看出规律,
I hate that I love that I hate it
I hate
I love
是来回循环的,不到最后一个每一次循环后面都输出 that,如果到最后则输出 it
1 #include<bits/stdc++.h> 2 using namespace std; 3 int main() 4 { 5 char a[2][20]= {"I love ","I hate "}; 6 int n; 7 while(~scanf("%d",&n)) 8 { 9 int x=1; 10 for(int i=0; i<n; i++) 11 { 12 printf("%s",a[x]); 13 if(i!=(n-1)) 14 printf("that "); 15 x=!x; 16 } 17 printf("it\n"); 18 } 19 20 return 0; 21 }
