Exercise 3 - String operations using pointers (4 marks) Exercise Objectives Pointer operations and pointer arithmetic with strings Strings as references Using pointers to loop through string elements Performing string operations using pointers Passing strings to functions as references Problem Description Within replit.com IDE, create another new repl (project) and name it "Lab11Ex3". Use this project to write and run a C program that performs the following: Use the symbolic constant to define the size of a string (1D array of char) of 50 Declare a variables named: mycity of the specified size Prompt the user to read mycity array Declare the following functions as prototype and implement them after the main function (NEVER USE string.h functions): o PrintChars(), a function that receives a char pointer. Use ONLY pointer arithmetic to print mycity characters Strlength(), a function that receives a char pointer. Use ONLY pointer arithmetic to get mycity length o VowelsCount(), a function that receives a char pointer. Use ONLY pointer arithmetic to get the number of vowels in mycity. (Note: you need to deal with the character cases here, 1.e. uppercase and lowercase of vowels) o ConvertToUpprcase(), a function that receives a char pointer. Use ONLY pointer arithmetic to convert mycity characters into uppercase. StrReverse(), a function that receives a char pointer. Use ONLY pointer arithmetic to convert mycity characters into uppercase. (Hint: define another pointer variable that points to the last element then move backward with this pointer. You need to call Strength() to reach the end of the array) In the main function: o Prompt the user to input mycity O Print mycity characters by calling PrintChars() function o Call Strength() for mycity and display the length Call VowelsCount() for mycity, and display the result Call ConvertToUpprcase() for mycity, then print myhobby Call StrReverse() for mycity, then print mycity O
