Initialising multidimensional arrays

So, I have this :

Code:

---

#include <iostream>
using namespace std;
int main(){
        char chr[1][256];
        chr[0] = "hello everyone!";
        chr[1] = "hello everyone!1";
        cout<< &chr[0] << "\n" << &chr[1];
        cin.get();
}

---

I am trying to initialise a multi dimensional c-style string, and then output it. But I get "Error E2277 chr.cpp 5:Lvalue required in function main()" when I try to compile it. The same error appears for the line 6, by the way.

Could anybody tell me what`s wrong about it ? I can`t figure out anything.

1. If you declare char chr[1][256], you don't have two rows in your multi-dimensional arrays, just one.
2. Once you hit the semicolon on the same line, it is then too late to do any initializing. You have to initialize when you declare:

Code:

---

char chr[2][256] = {"hello everyone!", "hello everyone!1"};

I thought of that, but I was not sure, though...

Thanks, it works now. :)

When declaring a multi dimensional array keep this formula in mind.
ARRAY [ROWS] [COLUMNS] , that is A [2] [5] means that array A has 2 rows and 5 columns. By the way I don't recommend you using cin.get(); , it sometimes doesn't work as it is supposed to. Better not use it as intended in here. Try alternate to this,

system("pause"); defined in cstdlib.

It should work as it is supposed to. When it does not work, it is because you failed to use it correctly, e.g., if your intention is to use it to pause execution after reading some input where the newline may be left in the buffer, then cin.ignore() should also be used.

The system function is part of the standard library, but whether "pause" does what you expect is another matter: "it sometimes doesn't work as it is supposed to."
