Simple Random Number Generator?

Question

Hi! I'm new to C++, and I would like to learn how to do a

simple random number generator!

From this code,

#include <iostream>

using namespace std;

void main (void)

{

}

What must I add to turn it into a random number generator,

for let's say, 52 numbers?

Answer 1

http://www.agner.org/random/randomc.zip

download that zip of .cpp files

File list

randomc.h

C++ header file containing class definitions.

You must #include this in all C++ files that use this library.

mersenne.cpp

Random number generator of type Mersenne twister.

ranrotb.cpp

Random number generator of type RANROT-B.

ranrotw.cpp

Random number generator of type RANROT-W.

mother.cpp

Random number generator of type Mother-of-all (multiply with carry).

rancombi.cpp

Template class for combining any two of these random number generators.

ex-ran.cpp

Example showing how to use these random number generators.

Answer 2

include &lt;cstdlib&gt;

#include &lt;ctime&gt;

#include &lt;iostream&gt;

int main()

{

    srand((unsigned)time(0));

    int random_integer;

    for(int index=0; index&lt;20; index++){

        random_integer = (rand()%10)+1;

        cout &lt;&lt; random_integer &lt;&lt; endl;

    }

}

This generates 20 random numbers between 1 and 10.
