hye..can somebody help me with these problems as soon as possible?? really need your guys help
Create a phone book program that allows users to enter names and phone numbers of friends and acquaintances. Create a structure to hold contact information .The user should be able to add phone book entries through a menu in a loop. Your structure should hold first name, last name, email address, and phone number.
Hint: Your main program should create a structure in by using example below.
2. Create the ability to edit contact information for a person (Add it to your menu). Ask the user for the first name, last name of the contact to edit. Search through your array and find the item. If the person is not in the list, then print a message to the user saying that. If the person is in the list, ask them for the new email address and phone number and update the structure accordingly.
3. Add the ability (another menu option) to save your contact information to a file. The data should be stored as name email address phone number
If you don't understand the requirements, ask a specific question instead of vague requests for "hints" and "help".
i am the first year student in the programming course.i am absolutely not understand it.
Teachers don't give an assignment without first covering the necessary material in class for completing the assignment. If you didn't pay attention in class and are now clueless as to how to do your homework, that's your own damn problem.
The '' values (note the square brackets, as opposed to parentheses, that's important) are the array sizes. When you write
what you are declaring is an array of size 20. When you then write
char ch = myArray;
you are then assigning the 5th value in the array (not fourth - array indices start at 0) to the character variable ch .
The reason you use character arrays for the character strings is because a plain char value can only hold one character at a time. So if you need to store the name 'John', you need to have an array capable of holding each of the letters in the name, plus one for the NULL Marker (a special character used to indicate the end of the string). By declaring the array to have size 20, you are giving it enough room for most personal names.
this is just an example..but i can't compile it.is there any mistakes in these codes?
If it doesn't compile, there are mistakes. That's axiomatic. If it doesn't compile, there are also compilation errors. Use them to fix the mistakes or post the errors so that others can help you fix the mistakes if you're incapable of doing so by yourself.
Umm...dude, dont take me the wrong way.. But if u dont know what  stands for, u shouldnt be looking to create a phonebook program from the start... I think it'd be better u expand ur knowledge about the following topics :
Basic Data Types - int,void,char,float,double
File Handling - To permanently store the phone numbers
(Even though the program can be done without structures... It'll be a lot harder)
