C++ error: “Array must be initialized with a brace enclosed initializer”

I am getting the following C++ error:

array must be initialized with a brace enclosed initializer 

From this line of C++

int cipher[Array_size][Array_size];

What is the problem here? What does the error mean? Below is the full code:

string decryption(string todecrypt)
    int cipher[Array_size][Array_size] = 0;
    string ciphercode = todecrypt.substr(0,3);
    string decrypted = "";
        string unit_decrypt = todecrypt.substr(0,Array_size);
        int tomultiply[Array_size]=0;
        for(int i = 0; i < Array_size; i++)
            tomultiply[i] = int(unit_encrypt.substr(0,1));
        for(int i = 0; i < Array_size; i++)
            int resultchar = 0;
            for(int j = 0; j<Array_size; j++)
                resultchar += tomultiply[j]*cipher[i][j]; 
            decrypted += char((resultchar%229)-26);
    return decrypted;


The syntax to statically initialize an array uses curly braces, like this:

int array[10] = { 0 };

This will zero-initialize the array.

For multi-dimensional arrays, you need nested curly braces, like this:

int cipher[Array_size][Array_size]= { { 0 } };

Note that Array_size must be a compile-time constant for this to work. If Array_size is not known at compile-time, you must use dynamic initialization. (Preferably, an std::vector).
