Homework • At the ‘Fortran 90 Tutorial’ at http://www.cs.mtu.edu/%7eshene/ COURSES/cs201/NOTES/fortran.html • Read through the sections – Selective Execution – Repetitive Execution – Functions (not modules - yet) • Do the exercises on the next slides and hand in by email (.f90 files)
Exercise 1: statements & loops • Write statements to – Declare a string of length 15 characters – Declare an integer parameter = 5 – Declare a 1-dimensional array with indices running from -1 to +10 – Declare a 4-dimensional allocatable array – Convert a real number to the nearest integer – Calculate the remainder after a is divided by b • Write loops to – Add up all even numbers between 12 and 124 – Test each element of array a(1:100) starting from 1; if the element is positive print a message to the screen and leave the loop
