Introduction of Programming
CS1001
Lab1(Mar 23rd)

Purpose

The goal of this laboratory is to give the students practice in editing, compiling and executing their programs under the UNIX windows environment.

Problem

• Log on to the system (if you don't know how to log on, the TA will help you).
• Create a directory cs1001 using the command mkdir cs1001. Move into the directory using the command cd cs1001.
• Create another directory lab1 using the command mkdir lab1. Move into the directory using the command cd lab1
• Enter the following program into a file called lab1.f90 by invoking emacs with the command

 

 

emacs lab1.f90 &

        PROGRAM Convert

!
!       This program converts temperatures from degrees Fahrenheit to
!       degrees Celsius.
!
!       variables:
!
!       Fahrenheit      input temperature in degrees Fahrenheit
!       Celsius         output temperature in degrees Celsius
!
        INTEGER Fahrenheit
        REAL Celsius
!
!       get the temperature in degrees Fahrenheit
!
        print *, 'Enter the temperature in degrees Fahrenheit'
        read *, Fahrenheit
!
!       convert the temperature to degrees Celsius
!
        Celsius = 5.0 / 9.0 * (Fahrenheit - 32)
!
!       output the temperature in degrees Celsius
!
        print *, 'The temperature in degrees Celsius is ', Celsius

        STOP
        END

• Exit emacs. Compile the file by typing in the command

f90 lab1.f90

If you encounter any fatal errors along the way, they must be corrected before proceeding to the next step. (Ask the TA for help if you get stuck).

• Execute the program by typing in the command

a.out
 
• Create a typescript file by typing in the command

script lab1.script

Execute the program again so that the execution is captured in the typescript file. Terminate script by typing exit

• Turn in your program and typescript file electronically by typing in the command

/cs/bin/turnin lab1 lab1.f90 lab1.script

See you next week!
