What Fortran does better than C-like languages
-
C-like languages (C, C++, Java) can do many things, but over the decades nothing much has changed with the inadequacies of some of their control structures.
Avoid ending lines in semi-colons?

I remember learning Fortran in college. I also remember disliking having to declare all variables at the top of the routine, and back then everything had indentation requirements (although I never used punch cards). C was a breath of fresh air. And C++ was the monkey's tail!

Also, contrast that to this old article: [On Choosing a Language for the User Client Functions](https://www.msri.org/publications/sgp/jim/software/mesh/desc/lang.html). Trying to figure out if Fortran has the equivalent of
virtualfunctions, and came across it. It seems modern Fortran does have some OO abilities, but did not see the answer to myvirtualquestion.Our Forgotten Astronomy | Object Oriented Programming with C++

I took Fortran after BASIC, to say it was a breath of fresh air would be an enormous understatement! Not dissing BASIC, the instructor I had seemed to encourage the spaghettification of code, to the point of insanity, it was my first programming class and it was painful. I had a math instructor who talked me into taking a Fortran class, wow what a (pleasant) eye opener! This has nothing to do with C or C++, but sometimes I think Fortran gets a bad rap.

Make pretty pixel art on punch cards? And of course you can exit a nested loop!
try
{
for (i=1; i<=10; i=i+1)
for (j=1; j<=10; j=j+1)
for (k=1; k<=10; k=k+1)
if (x[i][j][k] == 0)
throw new LoopyExit();
}
catch(LoopyExit)
{
}
// moving along...:laugh: Stunningly, I (and I suspect "we") have all seen this done, but of course not by us! :~

Quote:
In C-like languages exiting from a deeply nested loop isn’t exactly trivial (without the use of goto, so don’t even go there).
exitloop = 0
for (i=1; i<=10 && !exitloop; i=i+1) {
for (j=1; j<=10 && !exitloop; j=j+1) {
for (k=1; k<=10 && !exitloop; k=k+1) {
if (x[i][j][k] == 0)
exitloop = 1;
}
}
}Dumb. The dummy actually made a case for
goto. So I will.for (i=1; i<=10; i=i+1) {
for (j=1; j<=10; j=j+1) {
for (k=1; k<=10; k=k+1) {
if (x[i][j][k] == 0)
goto exitloop;
}
}
}
exitloop:
//do something amazing:It is cleaner than his code. Don't be hung up over trivial bullshit, and get the job done. (Not that I would do it this way, but every tool has a use.)

My immediate response is "That can't be Fortran that you are talking about??" Fortran was the language that made me hate implicit declaration of variables. "GOD is real unless declared integer"! (IMPLICIT NONE is the only statement related to implicit declaration that I like.) If you want me to do any programming job in a language with implicitly declared variables, I will demand double pay ... Even Fortran guys have come to their senses nowadays. On the other hand, during the discussions around what to include in Fortran 77, C.A.R Hoare remarked that "I don't know what programming languages will look like in year 2000, but they will be called Fortran. He hit the nail on the head.
