Note: You are not allowed to use any functions in the <string.h> library.
Develop a program that allows the user to enter a string and performing the following operations on it:
- Count Number of Characters In String
- Count Number of Words In String
- Remove Spaces In String
- Reverse String
- Reverse Words In String
- Look For Substring In String
- Insert Substring Into String
The following screen suggests a possible user interface:
Enter String: C is Fun!
1 ¡V Count Number of Characters In String
2 - Count Number of Words In String
3 - Remove Spaces In String
4 ¡V Reverse String
5 ¡V Reverse Words In String
6 ¡V Look For Substring In String
7 ¡V Insert Substring Into String
Enter Choice:
whereby:
If option 1 is chosen, 7 (including any special characters but excluding spaces) is shown on the screen.
If option 2 is chosen, 3 is shown on the screen
If option 3 is chosen, 'CisFun!' is shown on the screen
If option 4 is chosen, '!nuF si C' is shown on the screen
If option 5 is chosen, 'C si !nunF' is shown on the screen
If option 6 is chosen, get user to enter the substring he wants to find and display a message to tell him whether it is in the string
If option 7 is chosen, get user to enter a substring, and the position he wants to insert into the original string. The new string is then displayed on the screen.
