Arrays

• must declare with size

uint32_t array[10];
float matrix[5][6];

• do not have methods
  • array.size etc
• not bounds checked
  • can write past the end
• to know must keep trach yourself or use sentinel value
  • 'H' 'e' 'l' 'l' 'o' '\0' <- sentinel value

char *check = thing;

while(*check != '\0')
	check++

length = check - thing
