String comparison is an essential task in programming. Whenever we need to determine if two sets of data match, we need to perform a string comparison. But we need to understand further how to compare strings in
String as datatype In C, we know string basically a character array terminated by\0. Thus to operate with the string we define character array. But in C++, the standard library gives us the facility to use the string as a basic data type like an integer. Like integer comparisons, we ca...
Strings in C++String in C++ is considered as inbuilt data type like int, char, etc. That's why there have been various methods to compare strings. Below are the method description and examples.How strings are compared?Given two strings, how you will compare which one is greater and which ...

The following example uses the IndexOf method to search for the first occurrence of the 'l' character in a string.VB Copy Dim MyString As String = "Hello World" Console.WriteLine(MyString.IndexOf("l"c)) This example displays 2 to the console....
Now, let’s look at the performance of string.Compare(). As you can see from these benchmark tests, using Ordinal is close to the speed of using one of the equals. I hope that the .NET team continues to work on performance since this type of comparison is used a lot in applications...
1The first string follows the second string in the sort order. -or- The second string isnull. Dôležité TheString.Comparemethod is primarily intended for use when ordering or sorting strings. You should not use theString.Comparemethod to test for equality (that is, to explicitly look fo...
