Building and Running the Sequential Version

In Microsoft Visual Studio*, select Build > Build Solution. This builds the program. Run it by selecting Debug > Start Without Debugging. The console window contains the following program output:

Computing pi using 600000000 trials sequentially
Computed value of pi is 3.1415794, Relative Error: .422E-05
Elapsed time is 19.5 seconds

When the program is run again, a different computed value is given due to the different random number sequence:

Computed value of pi is 3.1415488, Relative Error: .139E-04
