C doesn't really have arrays - it has pointers with an indexing syntax. Furthermore, as Tim implies, what you think of as a two-dimensional array in C is actually an array of pointers to arrays. As Tim says, you'll have to adjust for this either in the ...
Note also that indexing such an array is reversed in Fortran and C, andindexing is also different (starting with 1 in Fortran and 0 in C), e.g. REAL:: B(10,5) B(7,3) <-> *(b + (3-1)*10 + (7-1)) <-> b[2][6] Jugoslav Translate 0 Kudos Copy link Reply tkhandan...

now whats the best way of array indexing them into a doubly linked list. im assuming ill need 3 arrays, and index/next/ and prev. any hints? Upvote 0 Downvote Jan 28, 2010 Thread starter #14 Mercfh Programmer Oct 26, 2009 13 US crap modula didnt work this code does work using...
In the following code example, you see the main computational kernel that updates the temperature on a 2D grid of points. It usesDO CONCURRENTloops to step through the 2D iteration space using the combined indexing capability ofDO CONCURRENTas described earlier. This expresses more parallelism and...

• definitions of functions returning array-valued expressions; • permutations of array indices allowing dimensionindependent definitions of unctions (see e.g. listings C.12 and C.13, P.10 and P.11, F.11 and F.12); • fractional indexing of arrays corresponding to employment of a stag...
