These are all issues a compiler could insert checks for, saving you the time to do it manually, while trading performance for security or correctness. C doesn't trade performance away, so if you'd like to pay the price of these checks, it's on you, the programmer to add them in. C programmers have to put in extra effort to make the executables safer and output correct results. Other languages trade off performance for safety and/or correctness. The programmers using them have to put in extra effort to make the executables run as fast as they do in C. Ultimately, programmers tend to make rational choices, and the stockholm syndrome mentioned above is really just C programmers dealing with the consequences of the trade-off they made by using C.
