Need some help with Ads

Hello guys how are you today ?
I want to make a simple question I quess. I have a wordpress website and I want to add ads in my articles like Adsense with exact dimensions and place. Do I need to add the code in every article ? can I use some sort of plug-in to add the ads where I want ? I need to edit the html code ? or I need to find the theme option ?

Thanks and take care!

There are tons of different adsense plugins for WP that could do the job without you having to copy and paste the code in every time you make a post. Go search in the wordpress plugin site, you can do this from within WP.

I got the adsense for wordpress , not so good i quess , I will copy the ads in the text. Thanks by the way!
