Write a C program to show pointers on string

Declare a string and assign a value to the string. You can assign the value in the program itself or you can get the string value from the user.

Declare a pointer assign this pointer to the string.

Write C code to do the following three operations.

$1.$ Print each character of the string.

$2.$ Replacing all the characters of a string and printing the updated string.

$3.$ Based on the position of the character, for example, you can replace an existing character with A for odd number index position and with letter B for even numbered characters in the original string.
