LAB 03: Standard Deviation Lab - Fortran Version

Objective
Learning Fortran 90 programming, Fortran 90 array processing. Topics include

1. Compiling Fortran 90 programs
2. keyboard I/O: read(*,*) and write(*,*)
3. File creation, writing to files
4. Arrays and loops
5. Matrix multiplication, subroutines, random numbers

Part 1

1. Download this program to write random numbers to a file: randomnums.f90
2. Run the program to create files of 50 or more random numbers
   -- Look at the contents of each of the number files to verify the programs worked.

Part 2 - Static Arrays in Fortran 90
printResults.f90 - shell file to print your results to a file

• Write a Fortran 90 program to put 1000 random numbers in an array. (See if you can increase this to 10000 or more without a segmentation memory fault)
• Print the array of values
• Find the highest and lowest values
• Find the average value
• Find the standard deviation
• Sort the numbers
