The strcase*-functions are not Standard C, but a POSIX extension. The strcmp function lexicographically compare two null-terminated character arrays.

int* foo(int bar) { int baz = 6; baz += bar; return &baz; /* (&baz) copied to new memory location outside of foo. */ } /* (1) The lifetime of baz and bar end here as they have automatic storage * duration (local variables), thus the returned pointer is not valid! */ ...

int x = 0; int y = 5 / x; /* integer division */ or double x = 0.0; double y = 5.0 / x; /* floating point division */ or int x = 0; int y = 5 % x; /* modulo operation */ For the second line in each example, where the value of the second operand (x) is zero, the behaviour is undefine...

Basics The Reflection API allows one to check the class structure of the code at runtime and invoke code dynamically. This is very powerful, but it is also dangerous since the compiler is not able to statically determine whether dynamic invocations are valid. A simple example would be to get the p...
