Assignment operators

Scripts > Class elements and c++ instructions > Interpreted C++ instructions > Operators > Assignment operators

Following assignment operators exist:

=    *=     /=    +=    -=   %=   ^=   |=   &=   <<=   >>=

The value of the operand Op1 after execution of the assignment

Op1 = Op2;

is equal to the value of Op2.

The expression

Op1 op= Op2;

has the same effect as

Op1 = Op1 op Op2;

Example: Op1 += Op2; is equivalent to Op1 = Op1 + Op2;.

The operands Op1 and Op2 must be either of the same type or they must be compatible to each other.

For Op2 also the call of a production or a token can be substituted, if they return a compatible value, and if the closing bracket of the semantic action is immediately following the operator:

Example:

{{e = }} Term

{{e += }} Term    

{{e -= }} Term
