Greetings, internet

I am quite new to Linux, and am looking to install a c++ compiler. I run 11.4, and was told to look in the Software Manager for easy installation. I have no repositories installed, as the repositories in the Application sticky only applied to Suse installations through 11.3.
I found the package "gcc45-c++" (Version Number 4.5.1_20...208-9.8) when I searched the Software Manager. I proceeded to install it, and had no problems, but when I looked in "applications", the compiler was not there. I'm aware that I may be revealing some great ignorance here, so I'll ask, should gcc appear? If not, how do I execute the program?

Thank you in advance
