Compile error
Posted by rGV 27 Nov 2007 01:40
what's wrong with my source? I can run it on my pc but there is "Compilation error"

#include <iostream>
using namespace std;

int quicksorta(int b[],int c[],int N)
{
    int  h = 0, f = N;
    int temp, p;
    p=b[N>>1];
    do
    {
        while (b[h]<p) h++;
        while (b[f]>p) f--;
        if (h<=f)
        {
            temp=0;
            temp=b[h];
            b[h]=b[f];
            b[f]=temp;
            temp=c[h];
            c[h]=c[f];
            c[f]=temp;
            h++;
            f--;
        }
    }
    while (h<=f);
    if (f>0)
        quicksorta(b,c,f);
    if (N>f)
        quicksorta(b+h,c,N-h);
    return 0;
}

int main()
{
    int i;
    int n;
    cin>>n;
    int c[n],b[n];
    for (i=0;i<n;i++)
        cin>>c[i]>>b[i];
    quicksorta(b,c,n);
    for (i=n-1;i>0;i--)
        cout<<c[i]<<" "<<b[i]<<endl;
    cout<<c[0]<<" "<<b[0];
    return 0;
}
