I've decided to use eclipse as my primary IDE for c++ coding but I can't seem to figure out the automatic autocomplete. When I press ctrl + space it shows them just fine but not when I'm typing normally. I tried browsing through the settings but in content assist setting under auto-activation it only has checkboxes for ., ::, and -> triggers and not for letters, numbers and parentheses. I tried browsing around the web and all the solutions were for the java version of the eclipse IDE, not the c++ one.
