i have a question regarding to convert from fortran language to C++ programming especially in diognal array for example; DO 10 I=1,3*(X+2) 10 ID(I)=(I-1)*m+1 how do i convert into C++ programming please someone help me

I'm not clear what the above code has to do with diagonal arrays; ID looks like a simple array to me. How about something like: int ID[SUITABLE_LIMIT]; for (int i=1; i<=3*(x+2); i++) ID=(i-1)*m+1; Don't forget C++ arrays are zero based so SUITABLE_LIMIT must be at least the maximum value of 3*(x+2) PLUS ONE. Also the above loop doesn't initialise ID[0]; watch out for that one, maybe use an array name that indicates it's 1-based rather than zero based, something along the lines of Hungarian Notation but simpler, e.g int ID_nz[..], nz meaning "no zero element". I always end up confusing myself if I use some arrays that are zero based and some that are not, in the same program.
