Iteration over Arrays

Two approaches to array iteration:
  • count-controlled, using size of array, e.g. 

    int i;
int v[10];
for (i = 0; i < 10; i++) {
	printf("%d\n", v[i]);
}

  • using a terminating value, e.g. 

    int i;
char s[10];
// somehow s[] is set to hold a C-string
for (i = 0; s[i] != '\0'; i++) {
	printf("%c", s[i]);
}
