* Read some integers into an array, then echo them.

#define ARRMAX 100
int arr[ARRMAX], /* Array of numbers. */
sub, /* Subscript. */
numin; /* Number of integers read. */
/* Rad them in. */
sub = 0;
while(scanf("%d", &arr[sub]) == 1)
numin = sub;
/* Print them back out again. */
for(sub = 0; sub < numin; ++sub)
C arrays are like Java's in syntax, and that subscripts start from zero.
The differences are really more substantial.
Most important is that arrays are declared and
allocated at the same time.
There is no new needed to allocate. Furthermore, there
are very few circumstances where you may omit the array
size, like int arr. Generally, the brackets must
contain a size, and that size has to be a constant.
That gives the amount of space to allocate.
