写一个程序，各位大虾帮我改改我的程序
#include <iostream>
#include <math.h>
using namespace std;
int one(int m)
{
if( m%4 == 1 ) return 1;
if( m%4 == 3 ) return -1;
}
int two(int m)
{
if( m%8 == 1 || m%8 == 7 ) return 1;
if( m%8 == 3 || m%8 == 5 ) return -1;
}
int main()
{
int m, p, q, s, t, mul=1,i,n;
cout << "请输入一个奇素数 p 和一个与它互素的正整数 m :\n\n ";
cout << "p = ";
cin >> p;
cout << "m = ";
cin >> m;
cout << endl;
s=m; t=p;
loop: if( m> p )
{
m%=p;
}
while( m%2 == 0 )
{
m/=2;
mul*=two(p);
}
if( m == -1 )
{
mul*=one(p);
goto mark;
}
if( m == 1 )
{
goto mark;
}
q=p; p=m; m=q;
if( (p-1)*(m-1)%8 )
{
mul*=-1;
}
goto loop;
mark: cout << "雅可比符号 ( ";
cout << s << " / " << t;
cout << " ) 的值为\t " << mul << endl << endl;
if(mul==1)
{
cout << "因此 " << s << "为模 " << t << "的二次剩余 " << endl;
for(i=1;;i++){
n=sqrt(p*i+m);
if(n==(int)n)break;
}
cout<<n<<endl;
}
else
{
cout << "因此 " << s << "不是模 " << t << "的二次剩余 " << endl;
}
return 0;
}
