col和row写反了尴尬

#include<iostream>
using namespace std;
int n, arr[45][45];
int main() {
cin >> n;
int col=0;
int row=n/2;
arr[col][row] = 1;
for(int i=2;i<=n*n;i++){
if(col0&&row!=n-1){
col=n-1;
row+=1;
}
else if(col!=0&&rown-1){
col=col-1;
row=0;

	}
	else if(col==0&&row==n-1){
		col=col+1;
	}
	else if(col!=0&&row!=n-1){
		if(arr[col-1][row+1]==0){
			col-=1;
			row+=1;
		}else{
			col+=1;
		}
	}
	arr[col][row]=i;
	
	
}
for(int i=0;i<n;i++){
	for(int j=0;j<n;j++){
		cout<<arr[i][j];
		if (j != n - 1) cout << " ";
	}
	cout<<endl;
}




return 0;
