# UVA 10783 Odd Sum
## 題目連結 [UVA 10268](https://vjudge.net/problem/UVA-10783)
### 題目內容
Given a range [a, b], you are to find the summation of all the odd integers in this range. For example, the summation of all the odd integers in the range [3, 9] is 3 + 5 + 7 + 9 = 24.
### 輸入限制
There can be at multiple test cases. The first line of input gives you the number of test cases, T (1 ≤ T ≤ 100). Then T test cases follow. Each test case consists of 2 integers a and b (0 ≤ a ≤ b ≤ 100) in two separate lines.

### 輸出限制
For each test case you are to print one line of output – the serial number of the test case followed by the summation of the odd integers in the range [a, b].
### 解題思路
1.是奇數就相加
### 程式碼

#include<bits/stdc++.h>
using namespace std;
int main(){
    int t,kase=1;
    cin>>t;
    while(t--){
        int a,b,ans=0;
        cin>>a>>b;
        for(int i=a;i<=b;i++){
            if(i%2==1){
                ans+=i;
            }
        }
        cout<<"Case "<<kase++<<": "<<ans<<endl;
    }
}
