Question

I’m getting an error in Visual C++ that is giving me a really hard time.

The error is error c2143 reading: syntax error: missing ‘)’ before ‘constant’

My code line is:

coefficient[i] = (1 - (2 * depth)) + ((t - floor( t + 0.5 ) + 1 ) 2 * depth);  

I have #include at the beginning of the file which should define the floor(double) function.

a bit more explanation of the variables.

double depth is a member variable of the class which this line can be found in.
int i is an incrementing index value.
double t is an incrementing value.

What they do is really unimportant, but I wanted to clarify that all three are already defined as variables of basic types.

I’ve gone through and verified that all the parentheses match up. I’m kind of at a loss as to what ‘constant’ the compiler is referring to. Any ideas?

Answer 1

I’m not quite sure if this is the same error that the compiler is giving you, but you have to put a ‘*’ sign in front of the second ‘2’ so that this:

coefficient[i] = (1 - (2 * depth)) + ((t - floor( t + 0.5 ) + 1 ) 2 * depth); 

Becomes this:

coefficient[i] = (1 - (2 * depth)) + ((t - floor( t + 0.5 ) + 1 ) * 2 * depth);
