Eclipse C ++ sets the width of the automatic line feed to 80

Generally, we use "CTL + Shift + F" to automatically typeset in eclipse.Code. The resolution of line 80 with automatic line feed at 1980 width is too short.

Setting method:

Choose Windows> pereference> C/C ++> code style.

Create a new profile because the preset profile cannot be edited. After you generate your own profile based on the preset, You can edit the row width.

Click new... and enter the new name test and OK. Select the new profile test. Click Edit. Select "line wrapping" in the tab and change 80.
