what does := mean in programming.?

Question

hi.

what does the statement

x := 5;

mean in programming.

thx!!

Answer 1

Hm....



















Assignment statement!

Store x with 5.

Answer 2

In Pascal it is the assignment operator, while = is the comparison operator. Thus x:=5 means x is now five while x=5 means true if x equals five and false otherwise.



In C/C++ it's the difference between x=5 and x==5..

Answer 3

Unix is an working device, like abode windows. Unix programming is programming for the Unix opereating device. each and every working device has unique valuable aspects, and demands categories of code. in lots of circumstances while human beings say Unix, what they actually recommend is *nix frequently. this implies a extensive determination of working platforms consistent with GNU, Unix, Linux and BSD that each and every person have comparable features.

Answer 4

X=5; would mean the variable X has the value of 5 assigned to it. more details, what language?



have you declared the variable? if so as what? a char? a long char? int? string?



good luck with programming

Answer 5

It usually means assignment.



x := 5 // set x equal to 5



Contrast with:



if x = 5 then ... // if x is equal to 5



This is different from languages like C but similar to languages like Pascal and is also widely used in pseudocode and generalised algorithm descriptions

Answer 6

Assignment in Ada or Pascal .

Answer 7

There is nothing like it in C++ OR php.. there are several like x!= or x+= or x-= nothing like what you just mentioned... :: Is used to use a class without declaring it.

Answer 8

I kind of resembles a linear programming module.
