TCS NQT Stacks and Queues Quiz – 1

EXPLANATION :

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

Stack is used to create an internal space for parameters and local variables.

when we want to add or place something in the stack so we need to perform push() operation.

When any user wants to delete an element from the stack which have 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 overflow condition.

The interruption that comes first  will be handled first.

The call which comes first so that first call receive first and other call stay in waiting.

When a lady wear the bangles so the last bangle she wore which is removed first. Thus the order is LIFO.

In the queue the element which is inserted first is removed first. So CPU give 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, it uses Queue.
