small code builds for .net

 In this lab, you will learn how to use the if-else double-selection statement.

Perform the following tasks in the C# block:

1. Declare a static public and character function grade with the parameter as marks having the datatype as integer.
2. Declare a character variable grd.
3. Use an if condition to check if the marks obtained are greater than 89 and less than 101, then return the variable grd as A.
4. Use the else if condition to check if the marks obtained are greater than 59 and less than 90, then return the variable grd as B.
5. Use the else condition to return the variable grd as C, if marks obtained are less than 59.
6. Return the value of the variable grd using the return keyword.

Note: In the C# block, replace the comments with the appropriate code, if required.

Sample input:

93

Sample output:

A

QUESTION 2

 In this lab, you will learn how to use the switch multiple-selection statement.

Complete the given code in the C# block by performing the following tasks:

1. Check the condition of the entered value and redirect it to the specific case.
2. For cases '+', '-', '*', and '/', add, subtract, multiply, and divide the variables a and b, respectively, store the result in the variable result, and take the control outside the switch block using the break statement.

Note: In the C# block, replace the comments with the appropriate code, if required.

QUESTION 3

 In this lab, you will learn how to use the while loop.

Complete the given code in the C# block by performing the following tasks:

1. Declare an integer variable count and set its initial value as 0.
2. Declare a while loop with the test condition as n > 0.
3. Increment the value of the variable count by adding the variable n to it.
4. Decrement the value of the variable n by 1.
5. Return the final value of the variable count as the returning value of the function after the control comes out of the iteration statement.

Note: In the C# block, replace the comments with the appropriate code, if required.

Sample input:

12

Sample output:

78

QUESTION 4

 In this lab, you will learn how to use the do-while loop.

Complete the given code in the C# block by performing the following tasks:

1. Declare and initialize the value of the variables result and i as 1.
2. Declare a do-while loop to store the product of the variables i and result in the variable result within the loop.
3. Increment the value of the variable i by 1, each time the loop executes.
4. Add a test condition for the do-while loop in such a way that the loop executes till the value of the variable i becomes greater than a.
5. Return the calculated value of the variable result using the return keyword.

Note: In the C# block, replace the comments with the appropriate code, if required.

Sample input:

5

Sample output:

120

QUESTION 5

 In this lab, you will learn how to use the for loop.

Complete the given code in the C# block by performing the following tasks:

1. Declare and initialize the variable fact as 1.
2. Declare a for loop with an initial value of the variable i as 1, test condition as i <= a, and increment value of the variable i by 1.
3. Calculate the product of the variables i and fact, and store it in the variable fact.
4. Return the calculated factorial stored in the variable fact using the return keyword.

Note: In the C# block, replace the comments with the appropriate code, if required.

Sample input:

QUESTION 6

 In this lab, you will learn how to use the for loop.

Complete the given code in the C# block by performing the following tasks:

1. Assign the Boolean value true to the variable prime using the bool function.
2. Use the if condition to check whether (a==1) returns false or (a==2) returns true.
3. Initialize the for loop with the variable i whose initial value is 2 and execute the loop until the value of the variable i becomes less than or equal to a/2.
4. Use the if condition to check whether the variable a returns 0 when it is divided by i.
5. If the above condition is true and the remainder of a/i is zero, then set the value of the Boolean variable prime as false.
6. Set the variable prime as the returning value of the function.

Note: In the C# block, replace the comments with the appropriate code, if required.

Sample input:

97

Sample output:

True

QUESTION 7

 In this lab, you will learn the concept of functions and work with them.

Complete the given code in the C# block by performing the following tasks:

1. Declare a static public and integer function Average with five parameters as a, b, c, d, and e having the datatype as float.
2. Calculate the average of the five variables and save it in the integer variable avg.
3. Set the variable avg as the returning value of the function Average.

Note: In the C# block, replace the comments with the appropriate code, if required.
