The result for the Postfix Expression ab*cd*+ where a=2, b=2, c=3, d=4 is

The postfix expression is evaluated from left to right using a stack.

1. Push 'a' into the stack. (Stack: 2)
2. Push 'b' into the stack. (Stack: 2, 2)
3. Pop two elements from the stack, multiply them and push the result back into the stack. (Stack: 4)
4. Push 'c' into the stack. (Stack: 4, 3)
5. Push 'd' into the stack. (Stack: 4, 3, 4)
6. Pop two elements from the stack, multiply them and push the result back into the stack. (Stack: 4, 12)
7. Pop two elements from the stack, add them and push the result back into the stack. (Stack: 16)

So, the result for the Postfix Expression abcd+ where a=2, b=2, c=3, d=4 is 16.
