how to Counter intval according to condition

[jjqcat]

Hi, I try to counter Intval according to some condition, as below
std::vector X(10);
for(i=0; i < 10; i++)
{
X[i] = model.NewIntVar(0, 10, 'X') # Decision Variable
}
A = model.NewIntVar(0, 100, 'A') # counter X[i] >1

  How to count the numbers greater than 1 in array X？ such as condition  if( X[i] > 1) A++;          
std::vector<IntVar> C(10);
in other words, how to do cp_model.AddEquality(C[i], X[i]> cp_model.NewConstant(1))
A = sum(C)

 cp_model.Maximize(A);

Or how to count the numbers less than 1 in array X? this code can't get valid result. cp_model.AddEquality(C[i], X[i] == cp_model.NewConstant(0));

The problem is:
cp_model.AddEquality(booleanA, x==y);
is that x==y "always" evaluates to false ,and also booleanA is false
