Hi,
Code:
Output:
When we declare a global array without initialization, all of its elements are getting initialized to a garbage value
#define MY_ARRAY_SIZE (5)
int a[MY_ARRAY_SIZE];
Ouput for line 102 is "a[] = {1,1,1,2,2}" which is garbage, expected "a[] = {0,0,0,0,0}"
When we define a global array with initialization (line 103-105)
int b[MY_ARRAY_SIZE] = {0};
int c[MY_ARRAY_SIZE] = {1};
int d[MY_ARRAY_SIZE] = {0,1};
Only the elements which value are specified are getting intilized where as the rest are garbge. Expected ouput to be
b[] = {0,0,0,0,0}
c[] = {1,0,0,0,0}
d[] = {0,1,0,0,0}
To initilizae all the element to "0" we need to initlize each and every element (line 105)
int e[MY_ARRAY_SIZE] = {0,0,0,0,0};
Is there any simple way to initialize all the elements to "0" for large arrays when we define a variable or am I missing something?
I can do a memset later but I want to initialize when I define.
Regards,
Vikky
