I have to do this example for my course work and I’m unsure what should I have to do with last case.
Create a method Pro(k) that generates k number of random integers and returns the sum of those in the interval [-10, 10]. In the main method, enter 3 positive integers a, b and c. To find and print: Pro( |c-b| ) * Pro(a).
This is my code for now:
In Main()
Console.Write("Enter k: ");
int k = int.Parse(Console.ReadLine());
Pro(k);
Console.WriteLine("Enter а = ");
int a = int.Parse(Console.ReadLine());
Console.WriteLine("Enter b = ");
int b = int.Parse(Console.ReadLine());
Console.WriteLine("Enter c = ");
int c = int.Parse(Console.ReadLine());
Console.WriteLine(Pro(c-b) * Pro(a));
//method Pro(k) is out of Main()
public static int Pro(int k)
{
int sum = 0;
for (int i = 1; i <= k; i++)
{
int num = int.Parse(Console.ReadLine());
if (num <= 10 && num >= -10)
{
sum = sum + num;
}
}
Console.WriteLine("Sum is: " + sum);
return sum;
}
>Solution :
This should be the correct answer |c-b| = Math.Abs(c-b) and it said Generates, not insert inside pro function so you should use random with interval (-10,10) te get those numbers. Anyway you advance a lot! please a console.writeline inside a method that return a value, also is a bad practice, you should return it first and then print it! hope it helps you!
static void Main(string[] args)
{
Console.Write("Enter k: ");
int k = int.Parse(Console.ReadLine());
Console.WriteLine("Sum is: " + Pro(k));
Console.WriteLine("Enter а = ");
int a = int.Parse(Console.ReadLine());
Console.WriteLine("Enter b = ");
int b = int.Parse(Console.ReadLine());
Console.WriteLine("Enter c = ");
int c = int.Parse(Console.ReadLine());
Console.WriteLine(Pro(Math.Abs(c - b))* Pro(a));
}
public static int Pro(int k)
{
int sum = 0;
Random rd = new Random();
for (int i = 1; i <= k; i++)
{
int rand_num = rd.Next(-10,10);
sum = sum + rand_num;
}
return sum;
}
