}


This program is giving many errors.

Here is what needs to be done in this program compulsory :
--> Calculator with 5 arithmetic operator.
--> Creation of a separate input function to take the input of two numbers and
operator from the user.
--> Must use pointers to give and receive values between functions.
--> Must give user the choice to repeat program.

The following output is predicted :
--->
Please enter first number : 5 
Please enter second number : 9

Please choose an operator to perform the operation :-
                             
                   + for addition
                   - for subtraction
                   x for multiplication
                   / for division
                   % for modulus

                            
                   Your choice : x


               Your answer : 5 x 9 = 45

Do you want to repeat the program (Y/N) ? __

If yes then goto arrow (--->)
If no then exit the program.



Any help is appreciated.
