what is explanation of sum+= buck [counter]

Question

public class GOICHI{
public static void main(String [] args){
int buck []= {1,2,3,4,5};
int sum = 0;
for (int counter =0;counter<buck.Length;counter++){
sum +=buck [counter];
}
System.out.println(sum)
}
}

Answer 1

ilia
in the above code
int buck [] = {1,2,3,4,5};
is an array containing 5 elements having index values from 0 to 4
1 will have index 0
2 will have index 1 and so on...
index means position it starts from 0

Now counter is a local variable having scope only in the for loop...
u can take any other variable name ...

inside for loop...
for(int counter=0; counter<buck.length; counter++)
👆 here when for loop will run the value of counter will change from 0 to 4...

buck[counter] will be changing from buck[0] to buck[4]
b[0] = 1st element = 1
b[4] = last element = 5

buck[counter] is used to access the elements of array according to their index position...

Answer 2

sum+=buck[counter] is same as
sum = sum + buck[counter]
the given code will give the sum of all the values in buck array

Answer 3

counter behaves as the index here
each time the for loop runs...
1st time for counter=0
buck[counter] = buck[0] = 1
2nd time for counter=1
buck[counter] = buck[1] = 2
until.......
5th time for counter=4
buck[counter] = buck[4] = 5
it will be added to sum...
resulting in sum = 15

Answer 4

bum[counter] =
b[0]
b[1]

until
b[4]

Answer 5

i know but i mean what is buck[counter]
