Fortran - do while 循环结构



当满足给定条件时,它将重复一个语句或一组语句。它在执行循环体之前测试条件。

语法

do while (logical expr) 
   statements
end do

流程图

do while

示例

program factorial  
implicit none  

   ! define variables
   integer :: nfact = 1   
   integer :: n = 1 
   
   ! compute factorials   
   do while (n <= 10)       
      nfact = nfact * n 
      n = n + 1
      print*,  n, " ", nfact   
   end do 
end program factorial  

当编译并执行上述代码时,它将产生以下结果 -

2             1
3             2
4             6
5            24
6           120
7           720
8          5040
9         40320
10        362880
