How does an array figures out the length.

How does an array figures out the length. Or is it because it count a letter one by one of a string (word)?

Example int[] arr={1,2,3,4,5}; arr.length() is 5 because arr has 5 elements

Muhd Khairul Amirin Bin Yaacob Array doesn't have length () method. We can figure out it's size by length instance variable. --> arr.length length () is available in String class to know the size of the string.

In C #include <stdio.h> int len(char s){ int c ,i; c=i=0; c=s[i] while ( c != '\0'){ i++; c=s [i] } return i; } int main (){ //creating character array char str [90];//Assume Hello World is the string int i = len (str);//length =10 }
