Array initialization with {0}, {0,}?

Question

Say I want to initialize myArray

char myArray[MAX] = {0};  
char myArray[MAX] = {0,};  
char myArray[MAX]; memset(myArray, 0, MAX);  

Answer 1

Assuming that you always want to initialize with 0.

--> Your first way and 2nd way are same. I prefer 1st.

--> Third way of memset() should be used when you want to assign 0s other than initialization.

--> If this array is expected to initialized only once, then you can put static keyword ahead of it, so that compiler will do the job for you (no runtime overhead)
