【HDOJ】1096 A+B for Input-Output Practice (VIII)

题目链接：http://acm.hdu.edu.cn/showproblem.php?pid=1096

Output

For each group of input integers you should output their sum in one line, and you must note that there isa blank linebetween outputs.

/*错误代码*/#include<iostream>using namespace std;void main(){int n,m,x,sum;while(cin>>n){for(int i=0;i<n;i++){sum=0;cin>>m;for(int j=0;j<m;j++){cin>>x;sum+=x;}cout<<sum<<endl<<endl;//错误}}}

/*正确代码*/#include<iostream>using namespace std;void main(){int n,m,x,sum;while(cin>>n){for(int i=0;i<n;i++){sum=0;cin>>m;for(int j=0;j<m;j++){cin>>x;sum+=x;}cout<<sum<<endl;if(i<n-1)cout<<endl;//正确}}}

总结：注意最后一行没有换行（a blank line between outputs）！
