C#: String with same characters
C# Sharp Basic: Exercise-96 with Solution
Write a C# Sharp program to check whether all characters in a string are the same. Return true if all the characters in the string are the same, otherwise false.
Sample Data:
("aaa") -> True
("abcd") -> False
("3333") -> True
("2342342") -> False
Sample Solution:
C# Sharp Code:
using System;
namespace exercises
{
class Program
{
static void Main(string[] args)
{
// Initializing different strings
string text = "aaa";
Console.WriteLine("Original string: " + text);
Console.WriteLine("Check whether all the characters in the said string are same or not! " + test(text));
text = "abcd";
Console.WriteLine("Original string: " + text);
Console.WriteLine("Check whether all the characters in the said string are same or not! " + test(text));
text = "3333";
Console.WriteLine("Original string: " + text);
Console.WriteLine("Check whether all the characters in the said string are same or not! " + test(text));
text = "2342342";
Console.WriteLine("Original string: " + text);
Console.WriteLine("Check whether all the characters in the said string are same or not! " + test(text));
}
// Method to check if all characters in a string are the same
public static bool test(string text)
{
// Check if the length of the string is greater than 1
if (text.Length > 1)
{
var b = text[0]; // Store the first character of the string
// Loop through the characters starting from the second character
for (int i = 1; i < text.Length; i++)
{
var c = text[i]; // Store the current character
// If the current character is not equal to the first character, return false
if (c != b)
{
return false;
}
}
}
return true; // Return true if all characters are the same or if the string has only one character
}
}
}
Sample Output:
Original string: aaa Check whether all the characters in the said string are same or not! True Original string: abcd Check whether all the characters in the said string are same or not! False Original string: 3333 Check whether all the characters in the said string are same or not! True Original string: 2342342 Check whether all the characters in the said string are same or not! False
