Input/Output

This program demonstrates reading input from the user and displaying output in Fortran.

Input/Output Statements

• print *, "message": Outputs text to standard output
• read *, variable: Reads input from standard input

The * in both statements indicates list-directed I/O, which automatically formats the input/output based on the variable type.

Implementation

program input_output
    implicit none
    integer :: num

    print *, "Enter an integer (press enter after you type it):"
    read *, num
    print *, "You entered: ", num
end program input_output

Example Interaction

Enter an integer (press enter after you type it):
42
You entered:           42
