Substring: Substring is defined as a string within a string. String can also be said as the array of characters and in C# the individual characters present in a string can be accessed using the subscript notation. Substring method of the string object is used to retrieve a specific set of characters from a string. Insert() method: This method is used to add a substring to the string and returns the string after the addition of the substring. Syntax: stringVariable.Insert(startPos, givenString) Remove() method: This method is used delete substring from the given string. This method returns the string after removing the substring. This can be done in two ways: stringVariable.Remove(startPos): This step deletes the substring starting from the index number specified as “startPos”. stringVariable.Remove(startPos, count): This step deletes the substring starting from the index number specified as “startPos” but stops as the number of deleted elements reaches the count mentioned in “count”.

Program Plan Intro

Substring:

Substring is defined as a string within a string.

String can also be said as the array of characters and in C# the individual characters present in a string can be accessed using the subscript notation.

Substring method of the string object is used to retrieve a specific set of characters from a string.

This method is used to add a substring to the string and returns the string after the addition of the substring.

Syntax:

stringVariable.Insert(startPos, givenString)

Remove() method:

This method is used delete substring from the given string. This method returns the string after removing the substring.

This can be done in two ways:

stringVariable.Remove(startPos): This step deletes the substring starting from the index number specified as “startPos”.

stringVariable.Remove(startPos, count): This step deletes the substring starting from the index number specified as “startPos” but stops as the number of deleted elements reaches the count mentioned in “count”.

The method does not return anything.Here is an example of a call to the method:showChar("New York", 2);In this call, the method will display the character w because it is in position 2. Demonstratethe method in a complete program-- use the class name Method_showChar Java

C# Write a method that accepts a string as an argument and displaysits contents backward. For instance, if the string argument is"gravity" , the method should display "ytivarg"

The method isupper() returns true if a string is in uppercase and false otherwise.True or False
