operator>= (<stack>)

_Left

An object of type stack.

_Right

An object of type stack.

true if the stack on the left side of the operator is strictly less than the stack on the right side of the operator; otherwise false.

The comparison between stack objects is based on a pairwise comparison of their elements. The greater than or equal to relationship between two stack objects is based on a comparison of the first pair of unequal elements.

      cout << "The stack s1 is greater than or equal to "
           << "the stack s3." << endl;
   else
      cout << "The stack s1 is less than "
           << "the stack s3." << endl;
}

The stack s1 is less than the stack s2.
The stack s1 is greater than or equal to the stack s3.
