2006: 寻找奇整数

解题思路:

注意事项:

参考代码:

#include<iostream>
#include<cmath>
#include<algorithm>
using namespace std;
int main()
{
    int arr[20]={3,7,5,13,25,45,78,23,8,33,9,19,28,41,50};
    int num;
    int loc=0;
    cin>>num;
    if(num%2!=0){
        for(int i=0;i<(sizeof(arr)/sizeof(arr[0]));i++){
            if(arr[i]==num){
                loc=i+1;
                break;
            }
        }
        if(loc==0)
			cout<<"Error"<<endl;
		else
			cout<<loc<<endl;
    }else{
        cout<<"Error"<<endl;
    }
    return 0;
}
