Practicing Return ValuesPracticing Return Values

Here operate is a method which is supposed to return true if a + b equals c. Fill in the blank to make the method behave accordingly.

cs

main.cs

1. We can write expressions directly in the return statement.
2. For-example, writing return a + b; is valid as it will first evaluate a + b and in-turn return the resultant value.
Similarly, we can also directly write boolean expressions in the return values, as boolean expressions are expressions after all.
Hence, writing return a > b; is also valid.
Using this information, think of a way how you can write a boolean expression which returns true if the sum of a and b is greater than c. 

using System;

namespace ConsoleApp
{
    internal class Program
    {
        static bool operate(int a, int b, int c)
        {
            return (a + b) == c;
        }

        static void Main(string[] args)
        {
            Console.WriteLine(operate(1, 2, 3));
            Console.WriteLine(operate(2, 4, 1));
            Console.WriteLine(operate(5, 10, 15));
        }
    }
}
