What are the limitations of the C programming language?

Answer 1

An algorithm simply describes the finite, procedural steps required to solve a problem. Algorithms are not specific to any one programming language, but without algorithms there would be no computer programs let alone programming languages. That is, you cannot program a computer to solve a problem unless you know how to solve the problem yourself and for that you need to know the algorithm. Once you have the algorithm, you can program the computer to implement it.

Answer 2

There are no limitations as such. All limitations are imposed by the hardware, not by the language. However, C is not an easy language to work with. Although easier to use and much less machine-dependent than assembly language, resource management is still the responsibility of the programmer rather than the language. C++ addresses these problems through resource handles, RAII (resource acquisition is initialisation) and exception handling, all of which make programming much easier but no less efficient than assembly. In many cases, C++ can produce code that is more efficient than C can because there is much less need for runtime sanity checks, such as checking that pointers are non-null before using them. User-defined types can take care of their own invariants, allowing the programmer to focus on using objects rather than worrying about the underlying implementation details of those objects, resulting in cleaner, task-oriented code rather than code that exposes distracting low-level functionality.
