Qus - 1: Draw a flow-chart to identify whether a number taken as the input from the user is an even number or an odd number?

Pseudocode is not an actual program. So, it cannot be executed.· Some of the frequently used keywords while writing pseudocode are INPUT, COMPUTE, PRINT IF/ELSE, START, STOP

Advantages of Pseudo-Code::

Qus - 2: Write a pseudocode for identifying if a number is even or odd?

INPUT number A

COMPUTE remainder as r = A%2

IF r ==0 PRINT 'Even'

ELSE PRINT 'Odd'

Decomposition:

Decomposition is the process of breaking a complex computer problem into smaller parts that are easily manageable and solvable.
