Array initialization

[Son_La]

if I declare an array

double test_values [] = {20.0, 30.0, 50.5, 101.5, 200.5};

if(debug)

{

    test_values [] = {20.0, 30.0,};

}

......

I got a compile error: expected expression

but if I do this

double test_values [] = {20.0, 30.0, 50.5, 101.5, 200.5};

if(debug)

{

    double test_values [] = {20.0, 30.0,};

}

......

during debug I found that the code stepped into the debug loop but the test_values array still have the original values (5 elements) instead of the debug values (2 elements)

I'm using LabWindows CVI 2015

Thanks in advance if you can help to answer

The reason for the first error is quite clear: the compiler assumes you want to assign an array element a value, but complains that no actual element is stated.

As per your second example, I don't think you can resize the array this way. I would rather rephrase the code using some preprocessor directive:

#ifdef _CVI_DEBUG_
	double test_values [] = {20.0, 30.0};
#else
	double test_values [] = {20.0, 30.0, 50.5, 101.5, 200.5};
#endif
