我是c++刚入门、希望各位高手能帮我看看是什么情况……
题目是这样的：分别对三个整数，三个实数，三个字符从小到大排序输出。要求：用重载函数实现。


下面是我的代码……

#include< iostream>
using namespace std;
int main ()

{
    int a[3];
    float b[3];
    char c[3];
    int i;

    for  ( i = 1 ; i <= 3 ; i++ )
    {
        cin >> a[i];
        cin >> b[i];
        cin >> c[i];
    }

    int z;
    z = line( a[1] , a[2] , a[3] );
    cout << a[1] << a[2] << a[3] << endl;

    float s;
    s = line( b[1] , b[2] , b[3] );
    cout << b[1] << b[2] << b[3] << endl;

    char f;
    f = line( c[1] , c[2] , c[3] );
    cout << c[1] << c[2] << c[3] << endl;

    return 0;

}

int line( int a[1] , int a[2] , int a[3] )
{
    int i , j , k;

    for ( i = 1 ; i <= 3 ; i++ )
    {
        for ( j = i -1 ; j <= 3 ; j++)
        {
            if ( a[i] > a[j] )
            {
                k = a [j];
                a[j] = a [i];
                a[i] = k;
            }
        }
    }
}

float line( float b[1] , float b[2] , float b[3] )
{
     float i , j , l;

     for ( i = 1 ; i <= 3 ; i++ )
      {
         for ( j = i -1 ; j <= 3 ; j++)
        {
            if ( b[i] > b[j] )
            {
                l = b[j];
                b[j] = b[i];
                b[i] = l;
            }
        }
    }
}

char line( char c[1] . char c[2] , char c[3] )
{
    char i , j , m;
      for ( i = 1 ; i <= 3 ; i++ )
      {
         for ( j = i -1 ; j <= 3 ; j++)
        {
            if ( c[i] > c[j] )
            {
                m = c[j];
                c[j] = c[i];
                c[i] = m;
            }
        }
    }
}

谢谢
