One of our apps has a C++ layer on top of FORTRAN. Lots of our C++ functions call the FORTRAN and have string arrays returned (in arguments). Currently this is done by allocating one large char variable in C++ and calling the FORTRAN, which actually returns an array of strings. We then...
Not "variable length" - what you have here is an array of strings all the same length. What would be passed is the starting address of the strings and, as a "hidden" parameter after all the explicit arguments, the string length passed by value (and of type size_t, not int!) I'm...
I would like to be able to pass an array of strings from c++ to fortran90. I am able to pass double arrays and character arrays with the following fortran module: MODULE rocker CONTAINS SUBROUTINEalltwice(numbers, doubles, n)INTEGER*4,INTENT(IN):: nREAL(KIND=dp),INTENT(IN)::numbers(1:...
部分风格同Emacs的F90 mode一致。 代码长度 每一行代码长度控制在120个字符以下。 续行 续航符为“&”,断行处也要有“&”符号 命名规则 全部小写; 不要起无意义的名字,尽量将名称保留一或两个音节;如果需要更多,请使用下划线来澄清(sortpair、whitechar、meshexp、numstrings、linspace、meshgrid、argsort、spline、...
Try input the following strings in the commandline: ! cir 20. ! sqr 10. ! rect 1. 2. CALL readcmd(keywd, pars) IF (keywd=='end') THEN EXIT ELSE IF (keywd=='cir' .OR. keywd=='sqr') THEN IF (size(pars) /= 1) THEN WRITE (*, *) 'Incorrect number of parameters.' ...

array = SCAN ((/'FORTRAN','VISUALC'/),(/'A', 'A'/))! returns (6, 5)! Note that when using SCAN with arrays, the string ! elements must be the same length. When using string ! constants, blank pad to make strings the same length.! For example:array = SCAN ((/'...
Fortran - 快速指南 转载自https://iowiki.com/fortran/,在此基础上做了一些补充。 Fortran - Overview Fortran,源自公式翻译系统,是一种通用的命令式编程语言。 它用于数字和科学计算。 Fortran最初由IBM在20世纪50年代开发用于科学
This is like direct I/O on external files, except that the number of records in the file cannot be changed. In this case, a record is a single element of an array of character strings. Example: Direct access read of the third record of the internal file, LINE: ...
That does not seem to be supported even by the suggested standard extension, but, hey, in the end we have two strings made of 4 characters, so deciding whether they are equal or not should not be very difficult. It's just a pitty that gfortran has never been told how to d...
