本人新手，纯自己想的。。请各位高手多多指点

求奇数与偶数和
# include <stdio.h>

int main (void)
{
    int a = 1, b = 2;
    int suma = 0, sumb = 0;
   
    for (a=1,b=2; a<=100,b<=100; a+=2,b+=2 )
    {
        suma = suma + a, sumb =sumb + b;   
    }
    printf("suma=%d\n sumb=%d\n",suma,sumb);
    return 0;
}

求平均值
# include <stdio.h>
int main (void)
{
    int a = 1;
    int suma = 0, sumb = 0;

    for(a=1; a<=100; a+=2)
    {
        suma = suma + a, sumb = sumb + 1;
    }
    suma = suma / sumb;

    printf("suma=%d\n",suma);

    return 0;
}

刚自学到for循环。。看视频上出了这几个题就试着做了下。。哈哈

我用VC++6.0可以成功运行啊。。for (a=1,b=2; a<=100,b<=100; a+=2,b+=2 )
