Array Problem Solving using C

Array Problem Solving using C#

Program Statement:

Create two arrays student_rollno and student_marks, both of same size. First array will save the rollnos of students and second array will save the marks of students against his rollno. e.g. if student_rollno[0] contains 197 then student_marks[0] will contains the marks of roll no 197.

You have to print the roll no of student with maximum marks.

Solution:

 public class stud
 {
 int n, max = 0, check = 0;
 public void marks()
 {
 Console.Write(" Enter number of students : ");
 n = Convert.ToInt32(Console.ReadLine());
 int[] array1 = new int[n];

C program to Find Worker efficiency using if else statement

C# program to find Worker efficiency using if_else statement 

Program statement:

In a company, worker efficiency is determined on the basis of the time required for a worker to complete a particular job. If the time taken by the worker is between 2 – 3 hours, then the worker is said to be highly efficient. If the time required by the worker is between 3 – 4 hours, then the worker is ordered to improve speed. If the time taken is between 4 – 5 hours, the worker is given training to improve his speed, and if the time taken by the worker is more than 5 hours, then the worker has to leave the company. If the time taken by the worker is input through the keyboard, find the efficiency of the worker.

Solution:

static void Main(string[] args)
 {
 double time;
 Console.WriteLine("Enter the Workers Time to complete Task:");
 time = Convert.ToDouble(Console.ReadLine());
 if (time >= 2 && time <=3)
 Console.WriteLine("Good! Worked Efficiently");
 else if(time>3 && time<=4)
 Console.WriteLine("Improved Your working Speed");
 else if(time>4 && time<=5)
 Console.WriteLine("Required Tranning to improve Speed");
