Write a program that initially asks the user to enter a positive integer number.

Question

Write a program that initially asks the user to enter a positive integer number.
After the acquisition of the number, it displays the following:

A[scii] R[affle] E[xit]
Please select an option:

Then, if the user selects:

- a (lowercase or uppercase): the program calls a user-defined function void ascii (int number) that displays whether the ASCII argument corresponds to digit, an uppercase letter, a lowercase letter or none of the above.

- r (lowercase or uppercase): the program calls a user-defined function bool raffle (int number) that takes the number input by the user as a parameter, generates an array of 5 random numbers ranging from 0-100 and displays then in a row. If the number passed as argument is present in the array, then it displays the position of the array where the number is found and the function returns true. If the number is not present, then it displays "number is not present" and the function returns false. Subsequently, the main() function saves the string "The number XX is present in the array" on the file, where 'XX' is the actual number,or saves the string "The number XX is not present in the array"

the file name is c:/FileHW7.txt

-e (lowercase or uppercase): the program exits.

Problem: The following program successfully does all the operations correctly, except for the highlighted portion i have given

Subsequently, the main() function saves the string "The number XX is present in the array" on the file, where 'XX' is the actual number,or saves the string "The number XX is not present in the array".

Can someone please help in making my code work properly. The problem lyes in case 'r': case 'R': part. The main() function does not save the string "The number XX is not present in the array" and that is what i am having difficulty in.  I am new with C++, and dont know what to do to fix this issue.
