12. Calculating the Factorial of a Number In mathematics, the notation n! represents the factorial of the nonnegative integer n. 1 he factorial of n is the product of all the nonnegative integers from 1 to n. For example, 7! = 1 × 2 × 3 x 4 X 5 X 6 × 7 = 5,040 and 4! = 1 x 2 X 3 X 4 = 24 Write a program that lets the user enter a nonnegative integer then uses a loop to calculate the factorial of that number. Display the factorial.

Exercise II Write a program that finds the positive integer solutions of the following equation ax³ + bx² + cx' + d = 0. The user enters the values of coefficients a, b, c and d. The program should test each integer starting from -50 to 50, and each time the equation is equal to zero, it prints its value as well as "is a solution". At the end, it displays the total number of positive integers found. Note that if the equation has more than one solution, the plural word “solutions" is used in the output. Sample run 1: Enter the coefficient of a, b, c, d: 1 -8.5 21 -13.5 1 is a solution 3 is a solution The equation has 2 integers as solutions Sample run 2: Enter the coefficient of a, b, c, d: 6 48 103.5 67.5 The equation has no integer solutions Sample run 3: Enter the coefficient of a, b, c, d: 1 -1 -12 0 4 is a solution The equation has 1 integer solution
Warm-up: Integer Operations Write a program that asks the user to enter two integers and prints the Difference, Product, Area of an Ellipse, and Average of these numbers. Here is an example of the execution of the program:
Java example to check if number is palidrom or not Number will be entered by the user
4) Roll the dice 2 Make a program that tests the probability of a certain score when rolling x dice. The user should be able to choose to roll eg 4 dice and test the probability of a selected score eg 11. The program should then do a number of simulations and answer how big the probability is for the selected score with as many dice selected. There must be error checks so that you cannot enter incorrect sums, for example, it is not possible to get the sum 3 if you roll 4 dice. TarningsKast2 How many dices do you want to throw? 11 Which number do you want the probability for? The probability the get the number 11 with 4 dices is 7.19% Calculate
C language Q4. Write a program that asks the user to enter an integer n, then prints the first n multiple of n. The program should keep asking to enter a number until -1 is entered. (0.5 point) Q5: a. What does the following program print? char c='Z'; for(i=1;i<= 4; i++) { for(j= 1; j<= i; j++) { printf("%c", C--); } printf("\n"); } b. Re-write the above code using while loop. Output: Sample Output: Enter a number: 4 48 12 16 Enter a number: 6 6 12 18 24 30 36 Enter a number: 1 1 Enter a number: -1 End Using while loop: (2x0.5 =1 point)
Arranging Pebbles Write a program that can arrange a group of pebbles into its designated position. We have 4 types of pebbles: Red, white, blue, and green colored pebbles. Supposed that we have an n-number of pebbles, the program should be able to check the color of the pebble and arrange them in such a way that it will look something like this: Example, if there are 9 pebbles; 1 green, 3 white, 2 blue, and 3 red, the program will output something like this: RRRWWWBBG NOTE: The program will let the user to enter the pebbles and then the program will automatically arrange it. Sample output 1: R=Red, W-White, B=Blue, G=Green Enter pebbles: rwgbrgwbrg Arranged pebbles: RRRWWBBGGG Sample output 2: R=Red, W-White, B=Blue, G=Green Enter pebbles: abcde Invalid input Notice that the arrangement of the pebbles is: Red, White, Blue, Green

Exo 11: klrote a the value Program that calculates the square rout of given numbers. It will stop when given 0, it will refuse negative values.
Perfect Number Checker: Create a program that checks if a given number is a perfect number. A perfect number is one where the sum of its divisors (excluding itself) equals the number.
Discrete Mathematics: Assignment details: Replace all the 0 (Zero) digits in your ID by 4. Example: If your ID is 38104680, it becomes 38144684 Take the first 6 digits and substitute them in this expression (( A + B) / C) * ((D-E)/F)-2) according to the following table; Letter Replace by Digit Example Digit A 1st 3 B 2nd 8 C 3rd 1 D 4th 4 E 5th 4 F 6th 6 After substitution your expression will be similar to this (( 3 + 8) / 1) * ((4-4)/6)-2).
