How to print [1,4,7,],[2,5,8],[3,6,9] in a matrix?

#5

your maxtrix is
1 2 3
4 5 6
7 8 9

and you want to print
[1,4,7,],[2,5,8],[3,6,9]
right??

for that just reverse the loops

for(int i=0;i<col;i++){
 cout<<"["
  for(int j=0;j<row;j++{
     cout<<arr[i][j]<<",";
  }

cout<<"]\n";
}

here you are iterating in each col
for i=0 means 0th column
you are iterating in every row j=0-row

so in this way it just print array col wise(vertically)

i hope this help
if you have more doubts regarding this feel free to ask
if your doubt is resolved mark it as resolved from your doubt section inside your course

I dont want to change the matrix from [1,2,3],[4,5,6],[7,8,9]. i just want to print [1,4,7],[2,5,8],3,6,9] matrix initially.

i just print it vertically

you can also check by printing the matrix after that
