Question
Create a menu driven application that recieves input from a textfile “Names.txt”, loads the names into an array, and outputs the array back into the textfile. Also provide a function to allow the user to change names.
The application should have the following functions:
void Read( string path, string names []);
Define a function that sequentially reads each name in the textfile and loads them into the array.
void Write( string path, string names[], int SIZE );
Define a function that saves each name from the array into the textfile. Write one name per line.
void ChangeNames(string names [] );
Define a function that allows the user to modify one of the names in the array. First ask the user for the index of the name that needs to be changed, and then ask them for the input.
void DisplayValues(string names [], int SIZE );
Display all the names stored in the array. Please see the screenshot below.
void DisplayMenu();
Display the following text:
Practice Challenge
----------------------------------------------------
1. Load names into the array
2. Display names
3. Change names
4. Save Changes
5. Exit
----------------------------------------------------
Enter a choice[1 – 5]:
int main() should do the following based on this PSEUDOCODE:
1. Create all variables for the filepath, SIZE, names array, and a choice variable.
2. Declare a string array of SIZE 5 called names
3. Display menu, and get choice from the user.
4. Clear Screen - system(“cls”)
5. Based on the user’s choice, call the appropriate function.
--case 1: Call Read function
--case 2: Call DisplayNames fuction
--case 3: Call DisplayNames function and call ChangeNames function
--case 4: Call Write function
--case 5: exit(1)
6. pause screen - system(“pause”)
7. Clear screen
8. While choice does not equal 5, repeat steps 3, 4, 5, 6, and 7
