Answer 1

copy the string to char array,then u can change any character
ex:
string str = "any string";
char [] arr = str.ToCharArray();
arr[0] = 'P';

Answer 2

The CS0200 error is caused when you try to assign a value to a variable that can only be read and not changed. To fix the CS0200 error you will need to find an alternative way of achieving the desired result.

Samsil Arefeen try this
take out lines 21 and 22
replace with:

String x = a.Replace("e", "v");
Console.WriteLine(x);

This is similar to Java

String x = a.replaceAll("e","v");

The first letter "e" is what letter will be changed throughout the sentence and the all the "e"s will become "v"s

Answer 4

char[ ] a = Console.ReadLine().ToArray();
a[2] = 'v';

Console.WriteLine(a);

string is read only

Answer 7

string is immutable, it cannot be changed after it is created, you can only create a new copy with the desired changes.

So any other way to change a char of a string?

Answer 12

Which error?

Answer 13

The body tag follows the head tag.
All visual-structural elements are contained within the body tag.

Headings, paragraphs, lists, quotes, images, and links are just a few of the elements that can be contained within the body tag
