The Catalan numbers are an integer sequence Cn that appears in tree-enumeration problems. The ﬁrst Catalan numbers for n = 1, 2, 3, ... are 1, 2, 5, 14, 42, 132, .... A formula generating Cn is:
Design two programs that communicate with shared memory using the Win32 API as outlined in Section 8.7.2. The producer process will generate the Catalan sequence and write it to a shared memory object. The consumer process will then read and output the sequence from shared memory.
In this instance, the producer process will be passed an integer parameter on the command line specifying how many Catalan numbers to produce (for example, providing 5 on the command line means the producer process will generate the ﬁrst ﬁve Catalan numbers).
Code in C++:
using namespace std;
int catalan(int n)
result = result+catalan(i)*catalan(n-i-1);
cout<<"enter the value of n:";
cout<<"C["<<n<<"] =" <<catalan(n)<<endl;
