honestly I have stuck and I don't know where to start...There are 9 functions of this program but I will post only the first 2 since
are the most confused.. So.. The first function called Read_a_customer() the informations of customer : id, name, address
should be added array in the array in the correct place according to alphabetic order of customer name.. also it will check if the customer
is already added... my serious problem is that I can't save an array since the customer_Details must be a structure and instead of it will be added the id,name and address.. This is my first problem, the second one came is on the second function that called print_details_of_customer() I have finally create that, but for some reason if i will added 2 customers in a row, it's replaced the older record by the new one... Now, it's seems logical since may array isn't change position and just overwrite the previous data but I have check it again and again and the position is change, so I think something is going wrong with the structures and the correct declarations please check my code below because am serious desperate... Also check the point with the alphabetic order end let me know if am correct or not since I am not able to check it without complete the first part...!!
::NOTE:: Please ignore all the unuseless variable...
Thank you in advance!! Regards!!!
