GCC knows how big an array is:

gcc knows the size of an array variable only in the scope of its definition: #include void f( int x[] ) { printf("f: sizeof a == %d\n",sizeof(x)); } int main() { int a[50]; printf("main: sizeof a == %d\n",sizeof(a)); f( a ); return 0; } ham% gcc arrsize.c ham% a.out main: sizeof a == 200 f: sizeof a == 4 Cheers, --Ham
