Count Positive Among Three
Programming Basics · C#
TASK
Problem
A line of space-separated integer values is given. Count positive among three according to the input data and print the count. Print the answer exactly in the required format; do not print input prompts or explanatory labels.
EXAMPLE
Example
3 4 5
3
LIMITS
Constraints
- Every token parsed with `int.Parse` is a valid 32-bit signed integer; test data avoid unintended overflow in the task's intended calculation. - Input is syntactically valid for the task except where invalid input is deliberately being tested (for example a `TryParse`/validation exercise). - Print only the required answer; do not add prompts, labels, debug text, or extra spaces/lines.

Theory for this problem
+
This is a direct arithmetic transformation. Name the input values, translate the formula exactly into C# operators, store the intermediate result when it improves readability, and print only the final value. For **Count Positive Among Three**, the concrete requirement is: Count positive among three according to the input data and print the count. Keep input parsing, the core operation, and output formatting separate so each part can be checked independently.

Solution

using System;
class Program
{
static void Main()
{
int[] p=Array.ConvertAll(Console.ReadLine().Split(),int.Parse);
int a=p[0],b=p[1],c=p[2];
int result=(a>0?1:0)+(b>0?1:0)+(c>0?1:0);
Console.WriteLine(result);
}
