assignment operators
Well that depends on what the type and value of variablename is, and what you're trying to check regarding it.
| wat am i trying to achieve with this type of code?? |
Do you want to execute the code inside the braces if variablename is zero, or if variablename is not zero?
I note that you called this thread "assignment operators" but there are no assignment operators in the code you presented.

see whatever i'm trying to achieve .. some form of execution.. i could've done with
" if(variablename!=0) " .. correct? instead i saw this convention somewhere and i want to know why its used..
" if(variablename!=0) " .. correct? instead i saw this convention somewhere and i want to know why its used..
It is valid syntax. The choice is yours - either will work. Some people get into the habit of putting the value first so that they cannot make the common mistake of writing:
when they meant to write
Both will compile and work, but they are very different.
Turning round the order means that writing
by mistake will cause a compile-time error, and only
if ( variable = 0)when they meant to write
if (variable == 0)Both will compile and work, but they are very different.
Turning round the order means that writing
if ( 0 = variable)by mistake will cause a compile-time error, and only
if ( 0 == variable) will work.

OK Thanks a lot.. So basically they are the same right? " if(0==var) " is essentially checking if var is zero.. right?
