On-Line C/C++ Courses?

Jon_S asks: "I've been happily hacking on Linux for five years now, and actually started playing with computers back as a 7th grader in 1972 on a PDP-8. Somehow I didn't get into a directly computer-related field, but I soon will be. I'm going back for a masters in GIS and I will need to have some solid programming background. I've coded FORTRAN programs back in college, read lots of programming books, and have written my share of shell scripts. The one thing I haven't tackled is C or C++ programming." Put simply, the submittor is hoping to find some quality C/C++ courses on line. Any hints?

"I know I can handle this stuff, I'm a certifiable geek, but to learn something you have to do it. The only way I see myself progressing this way is to take a course that will present the right types of programming challenges that I will need to develop my skill.

Searching on Google brings up tons of courses, but there is no way to tell whether any of these are any good. There are some great courses at RIT and I know this is a good school (friend of mine got a M.S. online there), but the good classes are filled this quarter and will probably next as well."
