"for" cycle as a function command - compsystems - 11-12-2018 08:42 PM
Hello
Xcas supports the definition of the "for" cycle as a function command FOR() ;, for many this type of instructions is more compact and readable, as IFTE() function cmd.
In the hpprime when writing the following sentences on history view, the system can interpret it.
PHP Code:
n:=1:; for j from 1 to 5 by 1 do n:=n*j end; n;
but the cycle for as a function test_for_2( ) does not.
PHP Code:
#cas
test_for1( ):=
begin
local j, n;
n := 1;
for j from 1 to 5 by 1 do n:=n*j; end;
return n;
end;
#end
test_for1( ) [enter] returns 120
PHP Code:
#cas
test_for2( ):=
begin
local j, n;
n := 1;
for( j:=1; j<=5; j++ ) n:=n*j ;
return n;
end;
#end
test_for2( )

It's not really a function. It's just syntactic sugar to appease programmers familiar with C-like syntax a little bit.
