Yes it will. The C standard requires that all unspecified array members be 0-
initialized if at least the first array member is explicitly initialized:
$ cat foo.c
#include <stdio.h>
int main()
{
int number[3]
#if INIT
= {0}
#endif
;
return printf("%d %d %d\n", number[0], number[1], number[2]);
}
$ gcc -Wall -O2 -o foo foo.c
$ ./foo
1628854574 47 2086312361
$ gcc -Wall -O2 -o foo foo.c -DINIT=1
$ ./foo
0 0 0
