c++ - Initialisation of char array to string value, are the uninitialised indices set to null? -

if have following:

char test[10] = "#"; 

is test[1] through test[9] guaranteed \0? or test[1] guaranteed \0?

this definition

char test[10] = "#"; 

is equivalent to

char test[10] = { '#', '\0' }; 

that 2 elements of array initialized explicitly initializers. other elements of array 0 initialized implicitly set tto '\0'

according c++ standard (section 8.5.2 character arrays)

3 if there fewer initializers there array elements, each element not explicitly initialized shall zero-initialized (8.5).
