Write necessary C code for doing the job

I like odd numbers a lot! I know it's your exam but you have to do me a little favor! I will give you a random integer number and you have to make it a Strongly Odd Number and check if it is a prime number or not. A strongly Odd Number is a number where every digit is an odd number. And Prime Number is a number that is divisible only by itself and 1. Write necessary C code for doing the job.

Sample Input:    Sample Output:

6594                    59. Prime

9805789              9579. Not Prime

Sample Output

We have RUNU and JHUNU with us from a distant village of Bangladesh...

Write a full C program for each of the following problems

We have RUNU and JHUNU with us from a distant village of Bangladesh who came to this Dhaka city for the first time. They have a special bag of money which gives them money every morning when they wake up from sleep. Somehow they figure out how much money each day they will be able to get from the magic bag in the next N days.

So, now they want your help to decide where to eat in this Dhaka city. Well for your help they also provided the list below:

• Roadside Food if the amount is 100 or less
• Fast Food if the amount is 250 or above but less than 350
• Kacchi if the amount is 350 or above
• Otherwise in BFC

Input: An integer N (No. of days). Followed by an integer in the next N line defining the amount of each of the N days.

Output: "Roadside Food", "Fast Food", "Kacchi" or "BFC" depending on the amount of each day. Table:

Sample Input:    Sample Output:

Create a robust encryption system for generate password

Create a robust encryption system for generate password

Cyber Security is a key issue to protect our daily documents and applications stored and submitted in various platforms. Having a sturdy coding system to our generated positive identification is incredibly essential during this perspective. Your task is to make a pleasant and swish encrypted positive identification generator. Follow the directions fastidiously to make the positive identification generator. [5 Marks]

a. Take a 5 digit integer number from user. Use a function named Input_Number() to require the amount from user. If the amount isn't exactly of 5 digits, provides a warning message to user and exit/abort the program.

b. In case of a 5 digit number, pass each digit of the amount to a user defined function named character_extractor() which might return a character like a digit. Character related to each digit will be within the following sequence.

c. Finally, pass your extracted characters during a user defined function named password_generator() to generate a 5 length password.

d. Show the password on screen.

Write a program in Java to perform the followings - Java Teacher Example | Java Method Overloading

1. Create a class Teacher with three private members Name, ID and Salary.
2. Design three constructors of the Teacher class to initialize an object with default values, three different values and the values of another object of the same class.
3. Design a display method to display the information of the calling object.
4. Create a TeacherExample class and define a main method inside it. Now create three objects of the Teacher class inside the main method with three types of initialization.
5. Display the information of the three objects of Teacher class
