Question
Create a program in C++ in netbeans that simulates a simple contact manager application given the following requirements:
1. The program is to store individual names and associated telephone numbers in parallel arrays.
2. The program should input from the user 10 people’s names and their telephone numbers and add the data to the parallel arrays.
3. When data input is finished, the program should sort both data arrays in ascending order based on telephone numbers maintaining the associations between names and telephone numbers.
4. The program will print the list of users and their telephone numbers after sorting.
5. After printing the list, the program will ask for a name to search for.
6. The user will then enter a name.
7. The program will then search for the name and print the name and the associated telephone number for that person.
8. If the person is not in the array, the program will print that the user cannot be found.
Modify the program you created above, to create a searchable telephone, by doing the following: The code for the input portion of the program is to be in a function by itself. This function will add individuals and their telephone numbers to the appropriate arrays. The code that sorts the arrays will be in a separate function. The function should take a parameter that indicates whether to sort ascending or descending. The code for printing the data from the arrays will be in a separate function. The code for searching for an individual in the arrays is to be in a separate function. The program should give the user the following menu options: Input data Sort data Ascending Sort data Descending Print all data Search for an individual in the data. End program The program will call the appropriate function based on user choice and the program will return to the menu afterwards (i.e. a perpetual loop). The program will only end when the user chooses End Program.
