how to initialize a char array?

Question

char * msg = new char[65546];

want to initialize to 0 for all of them. what is the best way to do this in C++?

Answer 1

The C-like method may not be as attractive as the other solutions to this question, but added here for completeness:

You can initialise with NULLs like this:

char msg[65536] = {0};

Or to use zeros consider the following:

char msg[65536] = {'0' another 65535 of these separated by comma};

But do not try it as not possible, so use memset!

In the second case, add the following after the memset if you want to use msg as a string.

msg[65536 - 1] =  '\0'
