Overall if you sent this in as the answer to an interview question for using C++ I would fail you and not give you the job. For a C job I suppose its OK. Tools (Algorithms/Data structures/Iterators) The C++ standard library contains a huge set of tools for you to use. You...

thedereferencing pointer to incomplete typeError in GCC Compiler For example, an undefined struct looks like this: structcircle{intlength;};intmain(){structround*x=0;*x;} In the above C program, it can be observed that a structcircleis constructed, but the struct called inside themainfunction...
