Question

Please complete the following problems regarding if statements and loops and submit by the end of class.

1. Write conditional expressions to perform the following tests:

a. When amountOwed is greater than 1000.00, display an overdue message.

b. When amountOfRain is greater than 5 inches, add 5 to total. When it is between 3 and 5 inches, add 3 to total. When it is less than 3 inches, add 1 to total.

---------------------------------------------------------------------------------------------------------------

2. What is the result of the following code segment?

int f = 7, s = 15;

f = s % 2;

if (f != 1) {

f = 0; s = 0; }

else if (f == 2) {

f = 10; s = 10; }

else {

f = 1; s = 1; }

Console.WriteLine(" " + f + " " + s);

---------------------------------------------------------------------------------------------------------------

3. Rewrite the following compound expression as a nested if statement:

if ((aValue > bValue) && (bValue == 10))

Console.WriteLine("Test complete");

---------------------------------------------------------------------------------------------------------------

4. Could a switch statement be designed logically to perform the same tests as the following nested if statement? If so, explain how it could be done

. if (aValue == 100) Console.WriteLine("Value is 100");

else

if (aValue < 100) Console.WriteLine("Value is less than 100");

---------------------------------------------------------------------------------------------------------------

Questions 5-8 refer to the following program segment.

int i = 0, g = 0, s = 0, t = 0, z = 0;

string sValue;

while (i < 5)

{ inValue = Console.ReadLine();

t = Convert.ToInt32(inValue);

s = s + t;

if (t > -1) g = g + 1; else z = z + 1; i = i + 1; }

5. How many times is the loop body of the while statement executed?

6. Describe the value stored in variable z at the end of the execution of the loop.

7. Categorize the loop (counter-controlled, sentinel-controlled, state-controlled, flag-controlled, etc.).

8. How many lines of output will be printed by the following fragment? What would they be?

for (int i = 0; i < 5; i++)

for (int j = 0; j < 4; j++)

Console.WriteLine("{0} {1}", i, j);

Explanation / Answer

1).
   a.
       double amountOwed;
       if(amountOwed > 1000)
           Console.WriteLine("Overdue: " +(amountOwed-1000));
   b.
       int total;
       if(amountOfRain > 5)
           total = total +5;
       else if(amountOfRain>=3 && amountOfRain <=5)
           total = total +3;
       else if(amountOfRain <3)
           total = total +1;
          
2) Ans 1 1

       because int f = 7, s = 15;

                   f = s % 2; after this line value of f = 1
               So, last else part will execute.
              
3).
       Using nested if else
      
       if(aValue>bValue){
           if(bValue == 10)
               Console.WriteLine("Test complete");
       }
      
4. Yes It is possible to write using switch statements.
   But you need to define 100 switch cases;
  
   switch(aValue){
       case 1:
       case 2:
       case 3:
       ............
       ............
       ..............
       case 99:
               Console.WriteLine("Value is less than 100");
               break;
              
       case 100:
               Console.WriteLine("Value is 100");
   }
  
5.   loop will executes 5 times for 'i' value: 0, 1, 2, 3, 4
6. Since value of t is 0 in all loop iteration.
   so, else part (z = z + 1), will always execute.
   initial value of z = 0 and loop executes 5 times
   so final value of z = 5
  
7. Since we are using 'i' as a counter (executes untill i value becomes 5),
   so this loop is counter-controlled
  
8. for each value of i (from outer loop), inner loop will executes 4 times(j value)
   since, i will take 5 values(0,1,2,3,4)
   hence, total number of output lines = 5x4 = 20
