In 1985, I was thinking of learning C while reading a Dr. Dobb's Journal on programming and saw an advertisement for a new C compiler by Mark Williams Company. They were producing some enterprise-level software but decided to write a low-cost C compiler and market it to hobbyists, or poor college students such as myself. This particular ad promised to give away the first 75 to whomever requested it. I was happily surprised to win my C compiler for the IBM PC adorably named, "Let's C."
A few years later, I wrote a reading comprehension program with Turbo C++. It was a graphical program that asked questions at the end of a story and graded the reader's answers. On that project, I was given the choice of language and although Turbo Pascal could've done the job quite well, I'm always interested in opportunities to grow my skill set and broaden my understanding of other tools.
More recently I have used Visual C# in several capacities, one of which was an application to synchronize customers, inventory, and sales between a web site and chain of sports stores. I've written DLLs and sample plugins for other systems and can read C# just as well as any other language.
But I could always write more robust code in less time with Pascal. So that's where I've kept the focus during my career.
