DISCUSSION:
In the past activity for looping statements, I learned the basic
fundamentals of a looping statement. For this activity, it enhances my skills
in using looping statements by solving the given machine problems. Most of
the given machine problems need to display the given integers accordingly.
Since in the last activity for looping statements I learned the basic
fundamentals of looping statements it becomes easier for me to create a
program that will be used to provide the proper output that is needed. The
only problem I encounter in solving the machine problem is creating a nested
loop because in the last activity for the looping statement nested loop is not
included. Since I know the basics of looping statements, I have an idea of
how to create a nested loop program. It is very important to know the basics
of looping statement because it will help you a lot in solving and creating a
program.
CONCLUSION:
The Looping statement is a program that can produce different numbers
accordingly. Also, a Nested loop is a part of a looping statement that allows
a loop inside another loop. And Nested loops have three types which are
nested for loop, nested while loop, and nested do-while loop. Nested loops
are used to cycle through a matrix, tabular data, and multi-dimensional
arrays.
