Most companies aren't interested in you recreating the wheel, they want you to get a working, maintainable product out the door in as little time as possible. Design patterns are more important to focus on than memory management these days.
C and C++ have their uses, but at the end of the day, C is little more than a macro-assembler and is completely inappropriate for most tasks in the business world. I've never worked anywhere where the C/C++ side of the project (there's always one group of holdouts) isn't consistently the long pole in the tent. After seeing several projects fail over this, I'd rather they "keep it real" on their own time.
