# C#: Check whether the sum of all 5' in the array exactly 15 in a given array of integers

## C# Sharp Basic Algorithm: Exercise-115 with Solution

Write a C# Sharp program to check if the sum of all 5' in the array is exactly 15 in a given array of integers.

Visual Presentation:

Sample Solution:

C# Sharp Code:

``````using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
class Program // Defining a class named 'Program'
{
static void Main(string[] args) // The entry point of the program
{
// Outputting the result of the 'test' method with different integer arrays as arguments
Console.WriteLine(test(new[] { 1, 5, 6, 9, 10, 17 })); // Testing the method with an array
Console.WriteLine(test(new[] { 1, 5, 5, 5, 10, 17 })); // Testing the method with another array
Console.WriteLine(test(new[] { 1, 1, 5, 5, 5, 5 })); // Testing the method with a third array
}

// Method to check if the sum of all occurrences of number 5 in the array is equal to 15
static bool test(int[] nums)
{
int sum = 0;

// Looping through the array
for (int i = 0; i < nums.Length; i++)
{
// Checking if the current element is 5
if (nums[i] == 5)
{
sum += 5; // Incrementing sum by 5 for each occurrence of 5 in the array
}
}

// Returning true if the sum of all occurrences of number 5 in the array is equal to 15, else false
return sum == 15;
}
}
}
```
```

Sample Output:

```False
True
False
```
