Question
I need help in finding the logical/syntax errors in this program:
// Creates a HomeworkAssignment class
// instantiates two objects
// and prompts the user for infromation about two courses using System;
class DebugNine1
{
static void Main() {
HomeworkAssignment course1 = new HomeworkAssignment();
HomeworkAssignment course2 = new HomeworkAssignment();
string entryString;
int exercises;
// Get info for first class
Console.Write("What class do you have homework for? ");
entry = Console.ReadLine();
course1.className = entryString;
Console.Write("How many exercises must you complete? ");
entryString = Console.ReadLine();
int.TryParse(entryString, exercises);
exercises = course1.NumberOfExercises;
// Get info for another class
Console.Write("What class do you have homework for? ");
entryString = Console.ReadLine();
course2.className = entrystring;
Console.Write("How many exercises must you complete? ");
entryString = Console.ReadLine();
char.TryParse(entryString, exercises);
course2.NumberOfExercises = exercises;
Console.WriteLine("You have {0} minutes of homework for {1}",
course1.timeToComplete, course1.ClassName); Console.WriteLine("and {0} more minutes for {1}", course2.timeToComplete,course2.ClassName);
}
}
class HomeworkAssignment
{
private int numberOfExercises;
private int timeToComplete;
// 10 minutes to complete each exercise
private const int TIME_PER_EXERCISE = 10;
public ClassName {get; set};
public int NumberOfExercises;
{
get
{
return numberOfexercises;
}
set
{
numberOfExercises = number;
CalcCompletionTime();
}
}
public double TimeToComplete
{
get
{
return timeToComplete;
}
}
private void CalcCompletionTime()
{
timeToComplete = numberOfExercises * TIME_PER_EXERCISE;
}
}
Explanation / Answer
1) You havent initiated "Entry" string before using it in entry = Console.ReadLine();
2)In ourse1.className = entryString; , you need to instantiate the class name using constructor for the class and the nuse getCLassname() and setClassname() functions and inside that you need to write return class name .
3)char.TryParse(entryString, exercises) , in this you havent written the metod definition for tryparse method anywhere in the program
4) You took the same string for number of exercises and class having homework . Both should have different string names
5)
private int numberOfExercises;
private int timeToComplete; access specifiers should not be praivate as they cannot be accessed by other parts of the program if they are priavate .Please make them public
