using c programming:

1.Implement Stack ADT (Abstract Data Type) with main ADT functions like push(), pop(), isStackEmpty(), isStackFull().Use Structure for defining the ADT. Use Static Array as a Data Member it can be of any type (Primitive or Userdefined).Declare necessary parameters and return types for the functions.

2. Implement Queue ADT(Abstract Data Type) with main ADT functions like enqueue(), dequeue(), getQueueSize(), isQueueFull(), isQueueEmpty(). Use Structure for defining the ADT. Use Static Array as a Data Member it can be of any type (Primitive or Userdefined).Declare necessary parameters and return types for the functions.

3. Write a program to evaluate a Postfix expression using Stacks. Get the Post fix expression in string format.
