float math_constants [2]; math_constants [0] = 2.71828; math_constants [1] = 1.41421; printf("Euler's number = %f", math_constant [0]);

float math_constants [2]; math_constants [0] = 2.71828; math_constants [1] = 1.41421; printf("Euler's number = %f", math_constant [0]);

I think your printf function is wrong. You declared math_constants (with an s) but referred to math_constant (without the s). It should be printf("Euler's number = %f", math_constants [0]);

The rest looks right, so it should work.
