Method Parameters

Question

Hello, It's again me! I have next problem:

A store is running a promotion: if the total purchase price is equal to or exceeds
10000, the price will be discounted by 20%.
The program you are given takes the total purchase price as input.
Complete the given method to take the total purchase price as an argument, and calculate and return the discounted price if campaign's requirement is satisfied.

The method should return the same price if discount is not given.

Sample Input
13000

Sample Output
10400

Explanation
13000>10000, so the discount should be given: 13000-(0.2*13000) = 10400.

Hint
You need to use if else statements inside the method.

Don't forget to mention the value type for the method parameter before its name.
Notice that method returns a value, so you need to use Console.Write()/Console.WriteLine() to execute the output.

using System;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
int totalPrice = Convert.ToInt32(Console.ReadLine());

//call the method

}
//complete the method declaration
static int Discount()
{
//complete the method body

}
}
}

That's a clear code

It's simple. You already have a method and you just need to pass parameter in that method.

As this method has return type int so you must return a integer value.

As program said get discounted amount if amount is greater than 10000 otherwise return original amount. So your complete method should be like this

static int Discount (int amount) {
if (amount > 10000) {
return (amount - 20 * amount / 100);
}

return amount;
}

And call this method inside main like

Console.WriteLine(Discount(totalPrice));

Answer 2

If anyone needs a working code, my answer looks like this:

static void Main(string[] args)
{
double totalPrice = Convert.ToDouble(Console.ReadLine());
Console.WriteLine(Discount(totalPrice));
}

static double Discount(double totalPrice)
{
if (totalPrice >= 10000){
double Discount = totalPrice - (totalPrice * 0.2);
return Discount;
}
else
return totalPrice;
}

For some reason, only the double type works correctly.

Answer 3

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
double totalPrice = Convert.ToDouble(Console.ReadLine());

//call the method
Console.WriteLine(Discount(totalPrice));

}
//complete the method declaration
static double Discount( double x)
{
//complete the method body
if ( x >= 10000){
double dd = x-(0.2*x);
return dd;
}
return x;

}
}
}

Answer 4

is it just me that thinks that this part of the course was bad written and they could have done a better work

Answer 5

Mehhh, I make 2 typo in my code... That's why it didn't work. You are right... I'm sorry for your lost time, and thank you so much for help..

Answer 6

Could you tell me

static void Main(string[] args)
{
int totalPrice = Convert.ToInt32(Console.ReadLine());

Console.WriteLine(Discount(totalPrice));

This is still a procedure? Or not?

I think you already got your answer then why again asking same problem and why deleted previous one.

I gave you right solution then what was mistake there?.

Answer 8

That was my mistake bro :/ I still have a problem to make a program

int totalPrice = Convert.ToInt32(Console.ReadLine());

//call the method
Console.WriteLine(Discount(totalPrice));

}
//complete the method declaration

}
}

I tried the above one but still its failing, can someone help??
