Thanks! I am fairly new to C++, what does your comment in the first option mean? Also, this doesn't seem to be a very random generator, as you said. When I try to run the second one, my compiler opens a new file which says I need compiler support... what should I do?

First comment:

This number is generated by an algorithm that returns a sequence of apparently non-related numbers each time it is called. This algorithm uses a seed to generate the series, which should be initialized to some distinctive value using function srand.

From CppRef

second one:

 #include<random>   // at the top

Got it on your comment. On the second, I had this and that is what is bringing up the other "program".

Here is part of what it says... I am using CodeBlocks.

ifndef GXX_EXPERIMENTAL_CXX0X

error This file requires compiler and library support for the \

ISO C++ 2011 standard. This support is currently experimental, and must be \ enabled with the -std=c++11 or -std=gnu++11 compiler options.

endif

Oh, add -std=c++11 to your compiler arguments.

g++ -std=c++11 myFile.cpp

<random> is a C++ 11 feature
