";s:4:"text";s:2561:" Looping control structures in a FORTRAN 77 program. 14.3 Loops. General Considerations. do i = 1, 10, 2 do something with i end do Syntax do while (logical expr) statements end do Flow Diagram Example. It prints out the numbers from 0 to 20 in steps of 1. Live Demo. See R818 and R819 (22.214.171.124) of the Fortran 2008 document. It tests the condition before executing the loop body.
The for loop is in Fortran is called the DO loop, but it is the same. 9. Statement: Terminates execution of a DO loop or a named construct. Later developments made it into a high level programming language. Various keywords are used to specify this statement: descendants of ALGOL use "for", while descendants of Fortran use "do". The Fortran standard now requires that a do construct's loop control is given by (scalar) integer expressions and that the loop variable is a (scalar) integer variable. Fortran Programming Guide. En Fortran comme dans la plupart des langages de programmation le signe = se lit "reçoit" et sert à assigner une valeur à une variable. It then distributes the work evenly over the available processors. 9. Fortran - Nested Loops - You can use one or more loop construct inside any another loop construct.
Fortran - do while Loop Construct. Advertisements.
Description . Previous Page. label .
EXIT will leave a loop. For repeated execution of similar things, loops are used. The loop control consists of the start, step, and stop expressions (your step expression is 0.5).
define variables integer :: nfact = 1 integer :: n = 1 ! In general, statements are executed sequentially : The first stateme If a DO WHILE statement appears within an IF, ELSE IF, or ELSE block, the range of the associated DO WHILE loop must be entirely within that block. DO (FOR). Previous: COMPLEX; Next: DATA; CONTINUE.
The do loop in Fortran IS a for loop:. Exercise 3.3. Loops For repeated execution of similar things, loops are used. Copy program loop.f95 program loop implicit none integer :: i do i=0,20 print *,i end do end program loop Run the program. You can also put labels on loops.
