hello

Program compilation and execution

In this exercise you will compile a simple Fortran program, and experiment with variable declarations and assignments.

1. Compile the supplied “Hello world”-program hello.F90 and run it.

2. Modify the program such that you define some variables and assign values to them. Try different types of numbers, logical values as well as strings.

3. Make some (likely less meaningful) computations using those variables and print out the values of those. Try to mix integer, real and complex types in computations and check how automatic type conversions behave (real -> integer, integer -> real, complex -> integer, etc.)
