Write program redact.c that reads entire lines from the user, and hides certain words according to a list of words received as program arguments, as illustrated in the following example.

the following requirements should be met.

Here are a list of requirements, assumptions and hints:

1.This program shall contain no global variables.

2. We assume that the maximum number of characters a line can contain is 80.

3. Censored words less than 2 characters should be ignored.

4. You will probably need to split the problem into a hierarchy of functions. A possible set of functions could include:

5. A function that hides a certain number of characters in a line, starting from a given position.

6. A function that hides a certain word in a line (e.g. by iterating through the string and locating the word).

7. A function that hides a collection of words in a line.

8. The main function should be the brain, reading the line from the user and calling the censor function before displaying the censored line.

In order to match strings while ignoring their case, you can use strncasecmp() function provided by the libc.

USEFUL FUNCTIONS----

List of some important libc functions that are used in the reference program: strlen(), strncasecmp(), fgets().

The example of execution is shown below---------
