Processing: Assignment operator

Assignment Operator

Assignment operator is used to assign a value to a variable.

   Syntax

      type variable = value;

   Example

      int a = 10.

      int b = 20

   Compound Assignment

      Syntax:

         variable operator= value

      Example:

         let’s say

         int a = 10;

         a+=10 evaluates to a=a+10

Compound Operator	Example	Description
+=	a+=10	a=a+10
-=	a-=10	a=a-10
*=	a*=10	a=a*10
/=	a/=10	a=a/10

Operators.pde

int var1 = 100;
int sum=10, sub=10, mul=10, div=1000;

println("sum+var1 is " + (sum+=var1));
println("sub-var1 is " + (sub-=var1));
println("mul*var1 is " + (mul*=var1));
println("div/var1 is" + (div/=var1));

Output

sum+var1 is 110

sub-var1 is -90

mul*var1 is 1000

div/var1 is10
