Too Many Initializers for 'Int [0]' C++

too many initializers for 'int [0]' c++

In C++11, in-class member initializers are allowed, but basically act the same as initializing in a member initialization list. Therefore, the size of the array must be explicitly stated.

Stroustrup has a short explanation on his website here.

The error message means that you are providing too many items for an array of length 0, which is what int [] evaluates to in that context.

C++ error: too many initializers for 'int [2]'

You declared the size of array is 2 but gave it 3 elements, I think just change it to int <array_name>[3] will fix the problem

C++ Error: Too many initializers for 'int [100]'|

Because 101 numbers don't fit into a 100 element array.

int SUM[100]; means that the array has exactly 100 elements, indexed from 0 to 99. It does not mean that 100 is the last valid index! That seems to be a common misconception among beginners.

I always remember it this way: There are 10 digits, namely 0 to 9. But there is no digit 10 :)

C++: array too many initializers

Try

array<X,2> a0 = {{{0,1}, {2,3}}};

Note the extra set of braces.

It seems a bit odd but it's this way because the only member of array is the actual array:

template <class T, size_t N>
class array {
    T val[N];
    // ...
};

The constructors are all implicitly defined so that array ends up being a trivially constructable type.

Too many initializers for Array error

You need more braces, since you're initialising objects within an array within a class:

Array points2 { { {1,2},{3,4},{5,6}}};
              ^ ^ ^
              | | |
              | | array element
              | array
              class

error: too many initializers for a struct

You get that error string when you do not enable c++11 mode or later in older GCC compilers (that defaults to c++03).

main.cpp:4:31: error: too many initializers for 'Data'
B(Data data) : m_data{data} {}

See it here. Although newer versions of GCC will give you more helpful diagnostics to enable c++11 mode.

So, just add to your compiler invocation:

-std=c++11
