The code i guess is right>? why is it throwing error?

#1

#include
using namespace std;
int main() {

int M,N;
cin>>M>>N;
int a[M][N];
for(int row=0;row<M;row++){
	for(int col=0;col<N;col++){
		cin>>a[row][col];
	}
}
int sc,sr,ec,er;
sc=sr=0;
ec=N-1;
er=M-1;
while(sc<=ec && sr<=er ){
	for(int i=sc;i<=ec;i++)
	cout<<a[sr][i]<<", ";
	sr++;

	for(int i=sr;i<=er;i++)
	cout<<a[i][ec]<<", ";
	ec--;
	
	if(sr<er){
	for(int i=ec;i>=sc;i--)
	cout<<a[er][i]<<", ";
	er--;
	}

	if(sc<ec){
		for(int i=er;i>=sr;i--)
	cout<<a[i][sc]<<", ";
	sc++;}
}
cout<<"END";
return 0;

}

Hello @rounaqkhandelwal24,

Change your conditions,
if(sr<er){} => if(sr<=er){}
if(sc<ec){} => if(sc<=ec){}
