C++ What's wrong with this spiral matrix code?

[Sourav Kumar Saw]

#include<bits/stdc++.h>
using namespace std;
void spiralprint(int arr[10000][10000],int m, int n){
int startrow=0;
int startcol=0;
int endrow=m-1;
int endcol=n-1;
while(startrow<=endrow && startcol<=endcol){
for(int i=startcol;i<=endcol;i++){
cout<<arr[startrow]<<" ";
}
startrow++;
for(int i=startrow;i<=endrow;i++){
cout<<arr[endcol]<<" ";
}
endcol--;
if(endrow>startrow){
for(int i=endcol;i>=startcol;i--){
cout<<arr[endcol]<<" ";
}
endrow--;
}
if(endcol>startcol){
for(int i=endrow;i>=startrow;i--){
cout<<arr[startcol]<<" ";
}
startcol++;
}
}
}
int main()
{
int arr[10000][10000];
int i,m,n,j;
cin>>m>>n;
for(i=0;i<m;i++){
for(j=0;j<n;j++){
cin>>arr[j];
}
}
spiralprint(arr,m,n);
}

You haven't said what your problem is.

And also, please put your code in the "Code" feature. The button should look like this: </>

As Johna said, you should always clearly state what problems you are facing. But I can see three things wrong to start with.

1 - This code does not compile because <bits/stdc++.h> does not exist. At least not in my Visual Studio 2022 environment.

2 - This code does not compile because you use cin and cout but do not have #include <iostream>.

3 - This code does does not compile because the compiler can't handle the statement cin >> arr[j]; The variable arr[j] is an array of 10000 int's, and there is no built-in C++ code to convert user input to an array - even if you typed in all your 10000 values, which you probably not intended to do.

Of course there may be more wrong with the code, once you get it to compile...
