Error problem show the hint

#1

Take as input a two-d array. Wave print it column-wise.

Input Format
Two integers M(row) and N(colomn) and further M * N integers(2-d array numbers).

#2

@MohdRaza whats your doubt share your code and doubt

#3

@MohdRaza you have to take user input and print answer according to that

#5

Take as input a two-d array. Wave print it column-wise.

Input Format

Two integers M(row) and N(colomn) and further M * N integers(2-d array numbers).

Constraints

Both M and N are between 1 to 10.

Output Format

All M * N integers seperated by commas with ‘END’ wriiten in the end(as shown in example).

#include

Correct code

#include
#include <bits/stdc++.h>
using namespace std;
int main() {
int a[10][10];
int m=0 , n=0;
cin>>m>>n;

for(int i = 0 ; i <m ; i++)
{
	for(int j = 0 ; j <n ; j++)
	{
		cin >> a[i][j];
	}
}
for(int j = 0 ; j<n ; j++)
{
	if((j%2) == 0)
	{
		for(int i = 0 ; i < m ; i++)
		{
			cout<<a[i][j]<<", ";
		}
	}
	else
	{
		for(int i = m-1 ; i >= 0 ; i--)
		{
			cout<<a[i][j]<<", ";
		}
	}
}
cout<<"END";
return 0;
