键盘输入一个整数，判断其奇偶。奇数就累加到SUM1，偶数就累加到SUM2。。


谢谢了

#include<stdio.h>
int main()
{
    int a,sum1=0,sum2=0;
    while(1)
    {
        printf("请输入一个自然数(输入负数结束输入)：");
        scanf("%d",&a);
        if(a<0)
            break;
        if(a%2!=0)
            sum1+=a;
        else
            sum2+=a;
        printf("sum1=%d\nsum2=%d\n",sum1,sum2);
    }
    printf("sum1=%d\nsum2=%d\n",sum1,sum2);
    return 0;
}
