#include <stdio.h>
void main ()
{
    int c, n, l;
    c=1;
    n=0;
    l=0;
    while (c<=10)
    {
        printf ("enter the numbers ");
        scanf ("%d",&n);
        c++;
        if (n>l)
            l=n;
        else l=l;
    }
    printf ("the largest is %d\n", l);
}

怎么用这程序求输入的10个数中的最大两个数？

就用while if 不行吗？

运行不了啊？

得到的结果是两个相等的数啊？

出现这些错

#include <stdio.h>
void main ()
{
    int c, n, l, sl, a;
    c=1;
    n=0;
    l=0;
    sl=0;
    while (c<=10)
    {
        printf ("enter ten numbers");
        scanf ("%d", &n);
        c++;
        
        if (n>sl){
            sl=n;
        if (sl>l)
        {a=sl;sl=l;l=a;}}}                                                                                                                                                                                                  
    printf ("the larger is %d\n", sl);
    printf ("the largest is %d\n",l);
}
这个可以了
