Cannot convert Brace-enclosed initializer list

I declare a table of booleans and initialize it in main()

const int dim = 2;
bool Table[dim][dim];

int main(){

     Table[dim][dim] = {{false,false},{true,false}};
     // code    
     return 0;
}

I use mingw compiler and the builder options are g++ -std=c++11. The error is

cannot convert brace-enclosed initializer list to 'bool' in assignment`

You can use memset(Table,false,sizeof(Table)) for this.it will work fine.

Here is your complete code

#include <iostream>
#include <cstring>
using namespace std;

const int dim = 2;
bool Table[dim][dim];

int main(){

    memset(Table,true,sizeof(Table));
    cout << Table[1][0] << "\n";
    // code    
    return 0;
}

First, you are trying to assign a concrete element of array instead assigning the full array. Second, you can use initializer list only for initialization, and not for assignment.

Here is correct code:

bool Table = {{false,false},{true,false}};

Arrays can only be initialized like that on definition, you can't do it afterwards.

Either move the initialization to the definition, or initialize each entry manually.
