Is a char array a pointer?

How do you sort a char array?

How do you convert this char array to string in C program?

Approach:

1. Get the character array and its size.
2. Create an empty string.
3. Iterate through the character array.
4. As you iterate keep on concatenating the characters we encounter in the character array to the string.
5. Return the string.

What is difference between char array and string?

String is implemented to store sequence of characters and to be represented as a single data type and single entity. Character Array on the other hand is a sequential collection of data type char where each element is a separate entity. String internal implementation makes it immutable in nature.

Return the string.

How do you declare an array in C?

Since arr+i points to i th element of arr,on dereferencing it will get i th element of arr which is of course a 1-D array.

We know,the pointer expression*(arr+i) is equivalent to the subscript expression arr[i].

To access an individual element of our 2-D array,we should be able to access any j th element of i th 1-D array.

How to convert a string to byte array in C#?

string authorName = “Here is a unicode characters string.

Encoding ascii = Encoding.ASCII;

Encoding unicode = Encoding.Unicode;

byte[]bytesInUni = unicode.GetBytes (authorName);

byte[]bytesInAscii = Encoding.Convert (unicode,ascii,bytesInUni);

char[]charsAscii = new char[ascii.GetCharCount (bytesInAscii,,bytesInAscii.Length)];
