Hi Luciana,

The problem is that the string you provided inside the printf statement does not produce the output that was required by the Challenge. After the code executes, you want the output to be Euler's number = 2.71828 :

float math_constants[2];
math_constants[0] = 2.71828;
math_constants[1] = 1.41421;

printf( "Euler's number = %f", math_constants[0] );
