    Parallel Array Problem

    I'm not sure if I did this properly. The program works fine but I don think that is what the problem is asking for.

    Any other ways to accomplish this task?

    Thanks in advance!

    Here's the problem
    Code:
    Name and load two parallel arrays for the following table.  Write a search routine (not a whole program) 
     that uses the input variable deptName to extract the access code.
    
    
    Department	Access Code
    Accounting	 1123X5
    Receiving	   1154V2
    Sales	             8823Q1
    Management    5412R7
    and my solution:
    Code:
    #include<iostream.h>
    
    int main()
    {
    	
    
    	char department[4][15] = {"Accounting", "Receiving", "Sales", "Management"};
    	char access_code [4][15] = {"1123X5", "1154V2", "8823Q1", "5412R7",};
    
    
    cout << "\n Please enter department number to retreive the access code:";
    cout << "\n Accounting = 1";
    cout << "\n Receiving = 2";
    cout << "\n Sales = 3";
    cout << "\n Management = 4" << endl;
    int deptName;
    cin >> deptName;
    
    
    
    		cout << department[deptName-1] << " ";
    		cout << "\nAccess code is: " << access_code[deptName-1] << endl;
    
    	
    
    	return 0;
    }

    since this is C++, use 'iostream' instead of 'iostream.h'. instead of using char[]'s use 'string's (youll need to #include<string> first) unless your required to use char[]'s or want to. after your include statements do "using namespace std;".

    the program looks like it will do what is asked. but it doesnt really 'search' for it. maybe he wants you to retrieve a string for the department name and use a for loop to loop through each element in department and compare the strings, then return the access code at that index.

    i think it would be either this way or the way you have it, but the way i described sounds more like 'searching', but i guess its up to the teacher and what he's been teaching you.

    Well, the assignment says to load the data, maybe implying input. It also sounds like deptName could be a string that you ask the user for, which might imply string comparison. You should probably just also check whether what the user enters is actually a valid department (in your solution, I could give it a number like 841875 and it would crash).
