ANSWER ALL QUESTIONS

Q1: Write a program that accepts a number and outputs valid if it is 5-numbers long. Example 1: x = 1234

 

Ans: Invalid

 

Example 2: x = 45321

 

Ans: Valid for processing

 

Q2: Modify the program in Q1 that adds all the digits of the entered number and display it in the form of an equation using loops?

 

For example: x = 56781

 

Ans: 5+6+7+8+1 = 27

 

Another example: x = 12345

 

Ans: 1+2+3+4+5 = 15

 

Note: the left-hand side of the answer must be dynamic.

 

Q3: Modify the program that you have written in Q1 to capture below scenarios:

 

1) If there is a number 2 in the entered number, then do not add.

 

For example: x = 73251

 

Ans: 7+3+5+1= 16

 

2) If there is a number 9 in the entered number, then multiply it by 2 and add. For example: x =12949

 

Ans: 1+2+18+4+18 = 43

 

See how I multiplied 9 with 2 two times.
