This suppose to show the empty map then display one with a x in the middle

#

And the thing is still empty

You never access vec1.at(1).at(1)

#

After the line vec1.at(1).at(1) = 'X'; You did a mistake

#

even before that the same problem is there

#

Not just this one, start with:

{
    {'1', '2', '3'},
    {'4', '5', '6'},
    {'7', '8', '9'}
};

and you'll easily notice what's wrong.

Yes I found out

#

I left the rest at row column

#

0

#

I fixed it thanks

upper dragon
#

row 0

supple lance
#

Yes

upper dragon
#

If you used debugger, you could have easily fixed this mistake

#

just keep it in mind for the future

supple lance
#

I have a debugger in vs studio

#

Sometimes it doesnt show anything

upper dragon
#

Are you putting a breakpoint and stepping over or stepping into lines of code?

supple lance
#

No

upper dragon
#

Because it always works and shows the values of things for me

supple lance
#

Ima need to look at tutorial on utube

upper dragon
#

You can also look up visual studio debugger on Google and they have a nice tutorial for you

supple lance
#

👍
