Union and structure are the special data type which allows storing different data types in the same memory.

 Union and structure are the special data type that allows to store different data types in the same memory

Read the following to understand -

• Stack


• Struct in C


• Union in C

The stack is used to create internal space for parameters and local variables.

When a woman wears bangles, the first bangle she wore goes down to the bottom and when she wore the last bangle, it will stay above. when she removes the bangle so, the bangle she wears, at last, will throw it first. Meaning they are using Stack topology.

In the queue, the element which is inserted first is removed first. So CPU gives the resources to the process which comes first.

When data is transferred asynchronously (data not necessarily at the same rate as sent) between two processes example include IO Buffers, pipes, file IO,etc.

The interruption comes first so it will be handled first.

The call which comes first, so this first call receive first and another call stays in waiting.

when we want to add element in the stack so we need to perform push operation.

When any user wants to delete an element from the stack when there was no element in the stack so this condition is known as the underflow condition.

When the user trying to push element more than its size so this condition is known as the underflow condition.
