executing the statement would set the upper and lower bounds the IloIntVar 'x1', but how to assign a specific integer value to "x1"?

I used the following code

x[0] = 2;

but comes with a compiling error 'error C2679: binary '=' : no operator found which takes a right-hand operand of type 'int' (or there is no acceptable conversion)'
any ideas? thanks;)

You cannot assign a value to an instance of IloIntVar.
If you want to fix a variable to a particular value then you need to set the lower and upper bound of that variable to that value. You can use the setLB and setUB member functions to do that.
