Draw Triangle

Problem Statement:

Draw a triangle for a given size, using given character and pointing toward given direction.

Language:

Java

Platform:

Command Prompt

Command:

[Program] -size [Size] -char [Char] -direction [Direction]

Expected Input:

[Size]: Any positive integer. Error should be printed if non-positive integer or string is given.

[Char]: Any single char. Error should be printed if more then one char is given.

[Direction]: R/L/U/D for Right / Left / Up / Down. Error should be printed if any other input is given.

Note: The order of parameters may change.

Hint: First make programme with fix order of parameter to get a working code. Then attempt to process the command line input for parameter reordering. This approach is known as modular approach for programming.

Expected Output:

Print the triangle of given size in given direction using given character. See example for better understanding.

Example:

Interface:

$ java DrawTriangle -size 5 -char A -direction R

Output:

A

AA

AAA

AAAA

AAAAA

AAAA

AAA

AA

A

Make Table

Problem Statement:

Write a program to generate a table of given number from command prompt.

Language:

Java

Platform:

Command Prompt

Command:

[Program] [Input Number]

Expected Input:

[Input Number]: Any Integer (positive or negative)

Expected Output:

Table of given integer from 1 to 10.

Example:

Interface:

C:\Program> java table 5

Output:

5 X 1 = 5

5 X 2 = 10

5 X 3 = 15

5 X 4 = 20

5 X 5 = 25

5 X 6 = 30

5 X 7 = 35

5 X 8 = 40

5 X 9 = 45

5 X 10 = 50

Input from Command

Problem Statement:

Take input from command prompt.

Language:

C and Java

Platform:

Command Prompt

Command:

[Program] [Input]

Expected Input:

[Input] : Any Message

Note: message is always separated by Space!

Expected Output:

Message 1: [Input 1]

Message 2: [Input 2]

...

Example:

Interface in C:

C:\Program> ./read_cmd.exe reading from cmd

Interface in Java:

C:\Program> java read_cmd reading from cmd

Output (Same for both C and Java):

Message 1: reading

Message 2: from

Message 3: cmd

Hello World

Problem Statement:

Print "Hello World" on screen.

Language:

C and Java

Platform:

Command Prompt

Command:

[Program]

Expected Input:

None

Expected Output:

Hello World

Example:

Interface in C:

C:\Program> ./hello_world.exe

Interface in Java:

C:\Program> java hello_world

Output (Same for both C and Java):

Hello World

Welcome

Dear Readers,

Programming is simpler then you really think... But in case, if you think that programming is not as simple as I think, then you are at right place. If you want to learn or revise programming, then this blog may help you. Here we will be posting the programming task and you will find solutions in the comment sections as it will be solved by us. This is because I am making this blog by writing each program one by one and revising my programming skill as well.

Good Luck.
