616 PointsAnswer to Task 1 challenge is wrong!
The task is to declare an array named math_constants that can hold TWO elements. The statement: "float math_constants[1];" generates an error.
The only answer the challenge will accept is "float math_constants[2];", the declaration for a THREE element array.

616 PointsPlease tell me why the declaration 'float math_constants[1]' will not create an array that will hold 2 numbers.

14,957 PointsBecause the way the syntax works is
float math_constants[number of elements in the array]
So, if you write 'float math_constants[1]'. The array contains ONE elements, which is essentially the same as creating a single float variable.
