Trouble with method subtraction c#

Question

I am experiencing some difficulty with method. My code seems to work just fine until I reach my formula for method. I have done something similar I'm not seeing what I'm doing wrong. It is the portion that has yearsToWork.

int age;
int yearsToWork;

Console.Write("Enter your name:");
string name = Console.ReadLine();

Console.Write("Enter your age:");
age = Convert.ToInt32(Console.ReadLine());

yearsToWork = 65 - age;
Console.Write("\nYou will work:", yearsToWork);
Console.Write("years before you retire.");
Console.Read();

Thank-you for the assistance.

Answer 1

Try this:

Console.Write("\nYou will work: " + YearsToWork.ToString());

As MSDN says, Console.Write :

Writes the text representation of the specified object to the standard output stream using the specified format information.

And that might not be the value you are expecting.

This should work:

    static void Main(string[] args)
    {
        int age;
        int YearsToWork;

        Console.Write("Enter your name:");
        string name = Console.ReadLine();
        Console.Write("Enter your age:");
        age = Convert.ToInt32(Console.ReadLine());
        YearsToWork = 65 - age;
        Console.WriteLine("You will work: {0} years before you retire", YearsToWork);
        Console.Read();
    }

Console.WriteLine(); work similar to string.Format(); when inserting a string;
The 1st parameter after the string will be {0}, second string {1} and so on...

The issue is you are calling Console.Write("\\nYou will work:", YearsToWork); which only writes the string and nothing else, if you wanted to generate a more elaborate message you should use string.Format or the Console.WriteLine . Your code should be something like this:

int maxWorkAge = 65;
Console.Write("Enter your name:");

string name = Console.ReadLine();
Console.Write("Enter your age:");
int age = Convert.ToInt32(Console.ReadLine());

int yearsToWork = maxWorkAge - age;

Console.WriteLine();
Console.Write("You will work: {0} years before you retire.", yearsToWork);
Console.Read();

Notice that I have set all variable names to lowerCamelCase and declared them as needed, also I made a variable (which could as well be a constant) for the 65 constant you were using. All these are best practice recomendations. Hope this helps
