C#: Square root of a given number
C# Sharp Basic: Exercise-93 with Solution
Write a C# Sharp program to calculate the square root of a given number. Return the integer part of the result instead of using any built-in functions.
Sample Data:
(120) -> 10
(225) -> 15
(335) -> 18
Sample Solution:
C# Sharp Code:
using System;
namespace exercises
{
class Program
{
static void Main(string[] args)
{
// Initializing integer 'n' with various values
int n = 120;
Console.WriteLine("Original number: " + n);
// Displaying the square root of 'n'
Console.WriteLine("Square root of the said number: " + test(n));
// Changing the value of 'n' and repeating the process
n = 225;
Console.WriteLine("\nOriginal number: " + n);
Console.WriteLine("Square root of the said number: " + test(n));
// Changing the value of 'n' and repeating the process
n = 335;
Console.WriteLine("\nOriginal number: " + n);
Console.WriteLine("Square root of the said number: " + test(n));
}
// Method to calculate the square root of a given number 'n'
public static int test(double n)
{
int sq = 1;
// Loop to find the square root using an iterative approach
while (sq < n / sq)
{
sq++;
}
// Checking if the square is greater than 'n/square'. If so, returns the square - 1
if (sq > n / sq)
return sq - 1;
return sq; // Returning the square root of 'n'
}
}
}
Sample Output:
Original number: 120 Square root of the said number: 10 Original number: 225 Square root of the said number: 15 Original number: 335 Square root of the said number: 18
