Answer 2

Example

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

Answer 4

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
}
