Answer:

The program in Python is as follows:

num = int(input("4 digit number: "))

numstr = str(num)

if(len(numstr)!=4):

    print("Number must be 4 digits")

else:

    numstr = numstr[::-1]

    num = int(numstr)

    print(num)

Explanation:

This prompts user for input

num = int(input("4 digit number: "))

This converts the input number to string

numstr = str(num)

This checks if number of digits is or not 4

if(len(numstr)!=4):

If not, the following message is printed

    print("Number must be 4 digits")

else:

If digits is 4,

This reverses the string

    numstr = numstr[::-1]

This converts the reversed string to integer

    num = int(numstr)

This prints the reversed number

    print(num)

Write a method called classAttendence() that creates a 10-by-10 two-dimensional array and asks for user input to populate it wit
gladu [14]

Answer:

The method written in Java is as follows:

public static void classAttendance(){

   Scanner input = new Scanner(System.in);

   String[][] names = new String[10][10];

   for(int i =0;i<10;i++){

    for(int j =0;j<10;j++){

       System.out.print("Student Name: "+(i+1)+" , "+(j+1)+": ");

       names[i][j] = input.nextLine();        

    }  

   }

}

Explanation:

This defines the classAttendance() method

public static void classAttendance(){

   Scanner input = new Scanner(System.in);

This declares the 2D array of 10 by 10 dimension as string

   String[][] names = new String[10][10];

This iterates through the rows of the array

   for(int i =0;i<10;i++){

This iterates through the columns of the array

    for(int j =0;j<10;j++){

This prompts user for student name

       System.out.print("Student Name: "+(i+1)+" , "+(j+1)+": ");

This gets the student name from the user

       names[i][j] = input.nextLine();        

    }  

   }

The method ends here

}

Write a program using integers user_num and x as input, and output user_num divided by x three times.Ex: If the input is:20002Th
HACTEHA [7]

Answer:

Following are the code to the given question:

user_num = int(input())#defining a variable user_num that takes input from user-end

x = int(input())#defining a variable x that takes input from user-end

for j in range(3):#defining for loop that divides the value three times

   user_num = user_num // x#dividing the value and store integer part

   print(user_num)#print value

Output:

2000

2

1000

500

250

Explanation:

In the above-given program code two-variable "user_num and x" is declared that inputs the value from the user-end and define a for loop that uses the "j" variable with the range method.

In the loop, it divides the "user_num" value with the "x" value and holds the integer part in the "user_num" variable, and prints its value.
