    Exclamation HELP! Strucutres!!

    I have this assignment, and the teacher said that it is open internet, open book, etc. I cannot figure out how to do the last part!

    1.Create an array that contains ten (10) variables of the following type:

    insert
    Code:
    typedef struct {
        char firstName[30];
        char lastName[30];
        char street[35];
        char city[20];
        char state[3];
        int zip;
        char phone[15];
        int accountId;
    } Customer;
    2.
    Prompt the user for values for each of the variables in each structure, i.e. you will be asking for 10 firstName values, 10 lastName values, and so forth. Hint: You should think about creating a function to input values for a structure, and then create a loop to call this function 10 times.

    3.
    After all of the values for the structure variables have been input, you need to prompt the user for a state string, and then display the values of all variables in each structure where the state string matches the user's input. Hint: You should think about creating a function to print all of the values for a structure, and then call the function for those structures that meet your criteria.

    You can assume that the user always enters proper data - no input validation is required.


    Sample Output

    Sample (user input in blue, program output in magenta)

    Pay attention with fgets:
    -Fgets automatically add the terminating null char after reading maximum N-1 chars.
    -Fgets returns a char*(or NULL) so you can't call it with an int variable (zip)
    -why do you specify 10 as number of maximum char to be read when firstName is an array of 30 char, state of 3 etc?
    Give a look here fgets - C++ Reference


    About the 3 point you can use strcmp - C++ Reference

    Hello,
    When you solve problems that root wrote, i would strongly recommend to use function in this program (you also get that hint in the assignment ). I would give you a idea how do it
    Code:
    Customer function (Customer x)
    {
        printf("Enter Name:")
        fgets(x.firstName,10,stdin); 
          // and so on //
         return x; // when you finished the function

    Do you know the difference between C and C++?
    This is C, so it would benefit everyone if you would post questions regarding this language in the C section in the future.
