how to initialize a char array?

In c++, I want to initialize char array to 0s array.
Will "char a[4096] = {0};" do this?

Answer 1

Yes it will… but keep in mind that a char being 0 is ASCII NULL… if you want it initialized to all '0' (character 0’s) that won’t work.

In this case:

memset(a, '0', 10);

Would be a better way to go… or

std::fill(std::begin(a), std::end(a), '0');

Would be better yet.
