Problem 1

Write a program that converts 1 lower case letter ("a" - "z") to its corresponding upper case letter ("A" - "Z"). For example if the user enters "c" then the program will show "C" on the screen.

Hint: You need to check the ASCII value in your program.

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;

namespace VP_Assignment1 { classProblem1 { staticvoid Main(string[] args) { char a; int b; Console.WriteLine("\t\tName: Ehtesham Mehmood\n\t\tRoll No: 11014119-131\n\t\tSection: AE\n \t\t UOG\n"); Console.WriteLine("Enter A Letter Between a-z:"); a = Convert.ToChar(Console.ReadLine()); b = (int)a; if (b >= 97 && b <= 122) { b = b - 32;

            a = (char)b;

Console.WriteLine("In Upper Case Letter:" + a); } else {

Console.WriteLine("You Enter Wrong Letter, Please Enter Letter Between a-z....!"); } Console.ReadKey();

    }
}

}

Problem 2

Console.WriteLine("\nAll points are fall on one straight line ");

        }

else {

Console.WriteLine("\nAll points are not fall on one straight line"); } Console.ReadKey(); } } }

Console.WriteLine("Points Lies On The Circle"); } if (coordinates_calculation> radius_square ) {

Problem 6

In a company, worker efficiency is determined on the basis of the time required for a worker to complete a specific job. If the time taken by the worker is between 2 - 3 hours, then the worker is said to be highly efficient.

Problem 41

Write a program that will input a charater "a" value from the user. You need to use a switch statement to decide if the value of a is "t" then you need to call the table function. If the value of a is "f" then call the factorial function, if the value of a is "p" then call the prime function, if the value of a is "s" then call the search function.

You need to write four functions in your program as in the following:

Table(int n1,n2) Factorial(int n3) Prime(int n4) Search(char n5[], char c, char choice) Table function will print the table of n1 from 1 to n2. Factorial function will print the factorial of n3 if n3 is a multiple of 2. Prime function will print the n4 if n4 is prime. Search function will take the first argument n5 as an array of characters and the second element a character to be searched for in the array and the third element a character to decide which searching algorithm is to be used, in other words if the user has passed the value of c as "s" then the Search function will perform the sequential search but if the value of c is something else then the Search function will perform a binary search. The structure of your program will be like this. You need to make it exactly working.

Problem 45

Create a class of student that stores characteristcs of a student, like studentID, studentName, studentDOB, studentRollNo, studentEmail, studentGPA of the last 5 semesters and other related information of the student. (You may set some properties Boolean and some readonly.)

Calculate the CGPA of each student using the function calculateCGPA(…). The student with the highest CGPA will be considerd CR of the class. There should be a function that will compare the CGPA of students and will declare a student having a greater CGPA as CR. The program should be able to take input of 5 students from the user; definitely there will be a function that will take input from the user. You need to use a Setter for setting the values of the data members of the class and a Getter function for getting the values of the data members of the class. (You can use a property as an alternative.) The default value for each student's GPA should be 3.0. (You need to use an array for storing GPAs of the last 5 semesters. You may simply initialize the array with 3.0 in the constructor). All data members should be private. Member functions can be public. The program must be able to add two objects, in other words if we add two students then all their corresponding data members will be added one by one. (Operator Overloading). The program must contain an explicitly defined copy constructor. StudentID and StudentGPA of the last 5 semesters must be constant or readonly. The value of studentGPA of the last 5 semesters must be selected from a enum that may contain values {1.0, 2.0, 3.0, and 4.0}. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;
