C++ 跳马问题-菜鸟提问

#include<iostream>
#include<cstdio>
#include<cstdlib>
#include<cstring>
using namespace std;
int head=1,tail=1,i=1,x,y,temp,pre;
int dx[5]={0,1,2,2,0};
int dy[5]={0,2,1,-1,-2};
int q[20];
struct Step
{
int x[20];
int y[20];
int pre[20];
};
int main()
{
Step q[20]={x,0,y,0,pre,0};
while(head<=tail)
{
for (i=1;i<=4;i++)
{
x=x*dx[i];
y=y*dy[i];
if((x<=7)&&(y<=4)&&(y>=0))
{tail++;
q[tail].x=x;q[tail].y=y;q[tail].pre=head;
}
if((x==7)&&(y==4))
{temp=tail;
while(q[temp].pre!=0)
{cout<<"("<<q[tail].x<<","<<q[tail].y<<")"<<" ";
temp=q[temp].pre;
}
}
head++;
}
}
system("pause");
return 0;
}

In function 'int main()':
[Error] incompatible types in assignment of 'int' to 'int [20]'
[Error] incompatible types in assignment of 'int' to 'int [20]'
[Error] incompatible types in assignment of 'int' to 'int [20]'
[Error] invalid conversion from 'int*' to 'int' [-fpermissive]
这种问题如何解决呢

Answer 1

不相容的数据类型，上面struct里面的数据是int型的数组，
访问需要用下标，如，q[tail].x[0]=x

Answer 2

一个数赋给整个数组怎么能行

追问

应该怎么做呢，上课没好好听，见教，感激不尽
