(This is initialization after the declaration in a separate line) Next, we declare and initialize two variables: height of type double with value 1.74, and name of type string with value "Anant". (This is initialization with declaration). After that, we use the cout command to print the ...
Pointers are a type of data in C; hence we can also have pointers to pointers, just as we have pointers to integers. Pointers to pointers offer flexibility in handling arrays, passing pointer variables to functions, etc. The general format for declaring a pointer to a pointer is. <datatype...

I realize nowI did not see the the possibility of using POINTER rather than ALLOCATABLE. I had gone off done a different way and was stumped on how to declare an array of POINTERS to ab objects as in[fortran]! Dllftrn3.f90 ! ! FUNCTIONS/SUBROUTINES exported from Dllftrn3.dll...
