memset is a common way to set a memory region to 0 regardless of the data type. One can say that memset doesn't care about the data type and just sets all bytes to zero. IMHO in C++ one should …

memset(arr,-1,6*(sizeof int)); Furthermore, if you only need to do this initialization once, you can actually declare the array to start with values 1 from compile time.

Jul 21, 2019 · I feel this is a risky habit, however. It's very difficult to be consistent, and in some contexts the program can crash if you make a mistake. Many developers seem to recommend initializing or …
