How do I format a statement in Fortran?
Fortran Formats
- Write the format as a character string and use it to replace the second asterisk in READ(*,*) or WRITE(*,*). READ(*,'(2I5,F10.
- Since a format is a character string, we can declare a character constant to hold a format string.
- We can also use a character variable to hold a format.

COMPLEX: the variable is capable of holding a complex number. LOGICAL: the variable is capable of holding a logical value (i.e., true or false)
What is the file type FORMAT for Fortran files?

What are the input statement in Fortran?
Input Statements: The digital computer can accept data from cards, tapes, disks or key-board. This process is called INPUT operation. The instruction in the FORTRAN program for an input operation is a statement that contains the verb READ.

What is the function of the Fortran where statement?
The where statement was introduced in FORTRAN 90 to aid in operations involving arrays. It provides a way to mask the assignment of arrays or the evaluations of arrays.
What is .F file in Fortran?
f a Fortran source code file is encoded and compiled using F format specifications and standards. The data contained in an F file includes source codes and other application details that correspond to a program developed using the Fortran programming language.
