Write a program to calculate the factorial value of the input number n! Use the incrementation formula ( i++ ) for your solution instead of decrementation formula (i-­‐-­‐).

Apply the three looping statements for your solutions:

Enter a no. 4 Factorial value is: 24 (The computation is: 1*2*3*4=24)

1st Solution – using for loop

2nd Solution – using while loop

3rd Solution-­‐ using do while loop

Write a program that generates and displays the Fibonacci sequences numbers of n (as input). In Fibonacci, the current third number is the sum of two previous numbers. Apply three solutions using the three loop statements: Sample input/output dialogue: Enter a no. 9 Fibonacci series: 1 1 2 3 5 8 13 21 34

1st Solution using for loop

2nd Solution – using while loop

3rd Solution-­‐ using do while loop

write a program that calculates the power value of the input base number and exponent number. Apply three solutions using the three looping statements: Sample input/output dialogue Enter base no. 5 Input data Enter exponent no. 3 Second input data Power value: 125 Output value (The computation is: 53 = 5 * 5 * 5 = 125)

1st Solution – using for loop

2nd Solution –using while loop

3rd Solution-­‐ using do while loop

Write a program to scan a number n and then output the sum of the squares from1 to n. Thus, if the input is 4, the output should be 30 because:12 + 22 + 32 + 42 1 + 4 + 9 + 16 =30

1st Solution – using for loop

2nd Solution – using while loop

3rd Solution-­‐ using do while loop

Write a program to calculate the sum of the sequence no. from 1 to n. Thus if the input is 6, the output should be 21 because: (Apply the three looping statements in your solutions) 1 + 2 + 3 + 4 +5 + 6 = 21

1st Solution – using for loop

2nd Solution – using while loop

3rd Solution-­‐ using do while loop

Write a program that reverses the input number n. Formulate an equation to come up with the answer:

(Apply the three loop statements in your solutions) Sample input/output dialogue:

Enter a number: 1238 Input data

Reverse number: 8321 Output value

1st Solution using- for loop

2nd Solution using- while loop

3rd Solution using- do while loop

Write a C# program that has a method named ReadArray. In this method, ask the user to enter names of employees, the program stops taking new names when the user enters the word “quit”. All names must be stored in an array as the user enters them; name the array, empNames. In the ReadArray, call another method named ReverseArray and pass to it, the empNames. The ReverseArray method will reverse the content of empNames. In ReadArray, print the reversed array. In the main method, only call the ReadArray, without passing anything to it. You should demo the pass-by-reference in this question.

Sample run:

Please enter an employee name: Karein

Please enter an employee name: James

Please enter an employee name: Komal

Please enter an employee name: Rohit

Please enter an employee name: quit

The names are:

Rohit

Komal

James

Karen
