Critical Thinking
Example 1: Write a pseudocode to declare the different types of
variables, assign them an appropriate value and then get the values
as an output.
Solution:
Program Start
Function Main
Declare
Declare Integer a
Declare Float b
Declare Char d
Declare String e
Declare Boolean f
Assign
Assign a = 1567
Assign b = 1. 567
Assign d = 'y'
Assign f = 'Hello world'
Assign e = false
