C++ is a superset of C, meaning it includes all of C's features along with additional capabilities. Most valid C code can be compiled by a C++ compiler, but the reverse is not true. C generally compiles faster than complex C++ code, especially when advanced features are used. However, the real decision between C and C++ depends on the type of problem you are solving and the trade-offs you are willing to make. Check out our C++ vs. C comparison to know all the differences.
