The String.ToUpperInvariant() method in C# is used to return a copy of this String object converted to uppercase using the casing rules of the invariant culture.SyntaxThe syntax is as follows -public string ToUpperInvariant ();ExampleLet us now see an example - Live Demousing System; using System.Text; public class Demo { public static void Main(String[] args) { string str1 = "one"; string str2 = "TWO"; string str3 = "ThrEE"; Console.WriteLine("String 1 = "+str1); Console.WriteLine("String1 ToUpperInvariant = "+str1.ToUpperInvariant()); Console.WriteLine("String 2 = "+str2); ...

The TimeSpan.FromTicks() method in C# is used to return a TimeSpan that represents a specified time, where the specification is in units of ticks.SyntaxThe syntax is as follows -public static TimeSpan FromTicks (long val);Above, the parameter val is the number of ticks that represent a time.ExampleLet us now see an example - Live Demousing System; public class Demo { public static void Main() { TimeSpan span1 = TimeSpan.FromTicks(18768768); TimeSpan span2 = new TimeSpan(-9, 45, 50); TimeSpan span3 = TimeSpan.FromHours(5); TimeSpan span4 = TimeSpan.FromMilliseconds(10000); TimeSpan span5 ...

The Object.GetHashCode() method in C# is used to serve as the default hash function.Syntaxpublic virtual int GetHashCode ();ExampleLet us now see an example - Live Demousing System; public class Demo { public static void Main() { Object ob = new Object(); String str = "Jim"; Type type1 = ob.GetType(); Type type2 = str.GetType(); Console.WriteLine("Hash Code = "+type1.GetHashCode()); Console.WriteLine("Hash Code = "+type2.GetHashCode()); } }OutputHash Code =30015890 Hash Code =21083178ExampleLet us now see another example:using System; public struct Value { private int v1; private int ...

The IsNullOrWhiteSpace() method in C# is used to indicate whether a specified string is null, empty, or consists only of white-space characters.Syntaxpublic static bool IsNullOrWhiteSpace (string val);Above, the parameter val is the string to test. Let us now see an example −ExampleLet us now see an example: Live Demousing System; public class Demo { public static void Main() { string str1 = null; string str2 = String.Empty; Console.WriteLine("Is string1 null or whitespace? = "+String.IsNullOrWhiteSpace(str1)); Console.WriteLine("Is string2 null or whitespace? = "+String.IsNullOrWhiteSpace(str2)); } }OutputThis will produce the following ...

The BitConverter.ToUInt16() method in C# is used to return a 16-bit unsigned integer converted from two bytes at a specified position in a byte array.Syntaxpublic static ushort ToUInt16 (byte[] val, int begnIndex);Above, val is the byte array, whereas begnIndex is the beginning position within val.ExampleLet us now see an example - Live Demousing System; public class Demo { public static void Main() { byte[] arr = { 10, 20, 30, 40, 50}; int count = arr.Length; Console.Write("Byte Array... "); for (int i = 0; i < count; i++) ... Read More
The TimeSpan.FromSeconds() method in C# is used to return a TimeSpan that represents a specified number of seconds, where the specification is accurate to the nearest millisecond.SyntaxThe syntax is as follows -public static TimeSpan FromSeconds (double val);Above, the parameter val is the number of seconds, accurate to the nearest millisecond.ExampleLet us now see an example - Live Demousing System; public class Demo { public static void Main() { TimeSpan span1 = TimeSpan.FromSeconds(0.6768788); TimeSpan span2 = new TimeSpan(25, 15, 45); TimeSpan span3 = TimeSpan.FromHours(.4788); TimeSpan span4 = TimeSpan.FromMilliseconds(0.8787); ... Read More
The TimeSpan.FromMinutes() method in C# is used to return a TimeSpan that represents a specified number of minutes, where the specification is accurate to the nearest millisecond.Syntaxpublic static TimeSpan FromMinutes (double val);Above, the value val is the number of minutes, accurate to the nearest millisecond.Example Live Demousing System; public class Demo { public static void Main() { TimeSpan span1 = TimeSpan.FromHours(0.78787); TimeSpan span2 = new TimeSpan(10, 30, 40); TimeSpan span3 = TimeSpan.FromHours(5); TimeSpan span4 = TimeSpan.FromMilliseconds(1); TimeSpan span5 = TimeSpan.FromMinutes(100); Console.WriteLine("TimeSpan1 = ...

The String.Contains() method in C# is used to return a value indicating whether a specified substring occurs within this string.Syntaxpublic bool Contains (string val);Above, val is the string to search for.Example Live Demousing System; public class Demo { public static void Main(String[] args) { string str1 = "Akon"; string str2 = "Ak"; Console.WriteLine("String 1 = "+str1); Console.WriteLine("HashCode of String 1 = "+str1.GetHashCode()); Console.WriteLine("String 2 = "+str2); Console.WriteLine("HashCode of String 2 = "+str2.GetHashCode()); Console.WriteLine("String 1 is equal to String 2: ...

In this tutorial, we will be discussing a program to implement t-test.The t-test of the student’s T test is used to compare two means and tell if both of them are similar or different. Along with this, t-test also helps to determine how large the differences are to know the reason for the change.Example#include using namespace std; //calculating mean float calc_mean(float arr[], int n){ float sum = 0; for (int i = 0; i < n; i++) sum = sum + arr[i]; return sum / n; } //calculating standard deviation float calc_deviation(float arr[], ...
