Can one use memset to fill an array of std::complexs?

Question

Specifically, I'm wondering if this line:

memset(cjzyp,(0,0),size_cjzy*sizeof(std::complex<float>));

will fill cjzyp, an array of complex<float>s, with the complex zero value ((0,0)).

memset(cjzyp,(0,0),size_cjzy*sizeof(std::complex)); Sorry there seems to be an error with the above line of code where the was omitted. Above is the correct one. — user1843784, Nov 22 '12 at 02:48

std::memset takes as second parameter an int converted to an unsigned char, it won't work. Use std::fill instead

cjzyp = new std::complex<float>[100]
std::fill(cjzyp, cjzyp + 100, std::complex<float>(-1.0, 0.0));
delete [] cjzyp;
