2、rsity Online Judge）.In this problem, your task is to calculate SUM（n） = 1 + 2 + 3 + . + n.InputThe input will consist of a series of integers n, one integer per line.OutputFor each case, output SUM（n） in one line, followed by a blank line. You may assume the result will be in the range of 32-bit sig

3、ned integer.Sample Input1100Sample Output5050AuthorDOOM III解答：#includemain（） int n,i,sum; sum=0; while（scanf（%d,&n）!=-1） sum=0; for（i=0;i=n;i+） sum+=i; printf（%dnn,sum）; 1089 A+B for Input-Output Practice （I）Your task is to Calculate a + b.Too easy?! Of course! I specially designed the problem for a

4、cm beginners. You must have found that some problems have the same titles with this one, yes, all these problems were designed for the same aim. The input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per line. For each pair of input integers a and

5、 b you should output the sum of a and b in one line, and with one line of output for each line in input. 1 510 20630lcyRecommendJGShining main（） int a,b; while（scanf（%d%da,&b）!=EOF） printf（%dn,a+b）; 1090 A+B for Input-Output Practice （II）Input contains an integer N in the first line, and then N line

6、s follow. Each line consists of a pair of integers a and b, separated by a space, one pair of integers per line. 2 #define M 1000void main（） int a ,b,n,jM,i; /printf（please input n:n）; scanf（n）; for（i=0;n; scanf（b）; /printf（%d %d,a,b）; ji=a+b; i=0; while（in） printf（,ji）; i+; 1091 A+B for Input-Outpu

7、t Practice （III）Input contains multiple test cases. Each test case contains a pair of integers a and b, one pair of integers per line. A test case containing 0 0 terminates the input and this test case is not to be processed.0 0 while（!（a=0&b=0） scanf（1092 A+B for Input-Output Practice （IV）Your task

8、 is to Calculate the sum of some integers.Input contains multiple test cases. Each test case contains a integer N, and then N integers follow in the same line. A test case starting with 0 terminates the input and this test case is not to be processed.For each group of input integers you should output their sum in one line, and with one line of output for each line in input. 4 1 2 3 45 1 2 3 4 50 1015#include int main（） int n,sum,i,t; while（scanf（=EOF&n!=0） scanf（t）; sum=sum+t; 1093 A+B for Input-Output Practice （V）Problem
