✅ Trying to count numbers on a string

I want to count how many times any number appears in the string, in a way such that: "2" then numbers ++ and "351" then numbers++ every time any number appears, instead of counting the digits.

Iterate over each character in a string, add to an integer if that character matches the specified number. I understood the first part of your question But could you elaborate on the rest?

Yes, basically every time any number appears the counter goes +1 For instance +1 for 235

So the amount of addition is not determined by the digit itself

TheOne1984•8mo ago

Instead of +3 for the digits Exactly, any number, if it has three, one or any digits it just adds +1

What's separating these numbers in the string?

TheOne1984•8mo ago

spaces

CrumpetMan•8mo ago

var numbers = str.Split(' ');
var counter = 0;

foreach(var num in numbers)
      counter++;

var numbers = str.Split(' ');
var counter = 0;

foreach(var num in numbers)
      counter++;

Can you explain it to me?

CrumpetMan•8mo ago

Pretty straightforward We're splitting the string with a whitespace splitter

TheOne1984•8mo ago

Oh I forgot, I cant use Split

CrumpetMan•8mo ago

Why is that?

TheOne1984•8mo ago

My teacher wont allow functions he hasnt taught us

CrumpetMan•8mo ago

Then create your own Split function

var numbers = new List<string>();
var tempStr = string.Empty;

foreach(var character in str)
{
   if(character !=  ' ')
       tempStr += character;
   else 
   {
      numbers.Add(tempStr);
      tempStr = string.Empty;
   }
}

var numbers = new List<string>();
var tempStr = string.Empty;

foreach(var character in str)
{
   if(character !=  ' ')
       tempStr += character;
   else 
   {
      numbers.Add(tempStr);
      tempStr = string.Empty;
   }
}

The fact I wrote this on my phone

TheOne1984•8mo ago

What is tempStr?

CrumpetMan•8mo ago

A temporary string

TheOne1984•8mo ago
