[华为机试]求出数组中全部奇数之和以及全部偶数之和

代码：

#include <iostream>
#include <sstream>
#include <fstream>
#include <string>

int main()
{
	int num[100];
	int odd = 0, even = 0;

	std::string str;
	getline(std::cin, str);
	std::stringstream s(str);
	int j = 0;
	while(getline(s, str, ','))
	{
	        //考虑了字符串中有非数字的情况（不考虑貌似也对了）
		int count = 0;
		for (int i = 0; i < str.size(); i++)
		{
			if(str[0] == '-')
			{
				neg = true;
			}
			if (str[i] >= '0' && str[i] <= '9')
			{
				count++;
			}
		}
		if (count != str.size() && !neg)
		{
			continue;
		}
		if( neg && count != str.size() - 1 )
                {
			neg = false;
			continue;
		}
		num[j] = atoi(str.c_str());
		if (num[j] % 2 == 0)
		{
			even  += num[j];
			j++;
		}
		else
		{
			odd += num[j];
			j++;
		}
	}
	std::cout<<odd <<","<< even;
}
