Each case starts with an integer N, and then N integers follow in the same line. Output For each test case you should output the sum of N integers in one line, and with one line of output for each line in input. Sample Input 4 1 2 3 4 5 1 2 3 4 5 Sample Output 10 15 题目分析： 刚看到该题目的时候似乎是之前做过，很顺手的就写出来啦 看来必要的练习还是有用的 */ #include <iostream> using namespace std; int main() { int n,a,sum=0; while(cin>>n) { sum=0; while (n--) { cin>>a; sum=sum+a; } cout<<sum<<endl; } return 0; } ~~~
