Structures

Ok, heres my problem.
i have a structure here it is:

struct route
{
char cityCode1[3];
char cityCode2[3];
char cityCode3[3];
char cityCode4[3];
char cityCode5[3];
char cityCode6[3];
char cityCode7[3];
};

route truckRoute;
int index = 1;

now, i'm assigning values( 3 letter chars) to the variables.. i want to be able to increment the variable names # (ex. cityCode1 to cityCode2) when I do a cin>>, would this be accomplished by the following set of code? or Could someone help me to determine the correct procedure

cin >>cityCode
cityCode = truckRoute.citycode<<index
index++

Make an structure of arrays of arrays of chars...

Code:

#include <iostream>
const int NUM_CODES=7;
const int CODE_LENGTH=3;

struct route 
{ 
     char cityCode[NUM_CODES][CODE_LENGTH]; 
}; 

int main() {
     route truckRoute;
     for (int i =0; i < NUM_CODES; i++) {
            std::cout << "Enter city code " << i + 1<< " for truck route: ";
            std::cin >> truckRoute.cityCode[i];
     }
     return 0;
}

Damm you beat me

but I think you need to declare CODE_LENGTH as 4 to take into account the '\0'

mind you i don't do much c++.

Ok, but is what I was suggesting possible??
i'm not that far ahead in my c++ courses to do what u suggest...

i just need a way to be able to input the 3 letter codes in sequence

No, what you said is not possible.

cin >>cityCode
cityCode = truckRoute.citycode<<index
index++

cityCode, without being bound to the name of a route, has no meaning. Also, I have absolutely no clue what this means...

cityCode = truckRoute.citycode<<index
