int [] arr = new int[10];
Which of the following code segments correctly interchanges the value of arr[0] and arr[5]?
Question 10 options:
A)
int k = arr[5];
arr[0] = arr[5];
arr[5] = k;
B)
arr[0] = 5;
arr[5] = 0;
C)
int k = arr[0];
arr[0] = arr[5];
arr[5] = k;
D)
int k = arr[5];
arr[5] = arr[0];
arr[0] = arr[5];
E)
arr[0] = arr[5];
arr[5] = arr[0];
A)
int k = arr[5];
arr[0] = arr[5];
arr[5] = k;
B)
arr[0] = 5;
arr[5] = 0;
C)
int k = arr[0];
arr[0] = arr[5];
arr[5] = k;
D)
int k = arr[5];
arr[5] = arr[0];
arr[0] = arr[5];
E)
arr[0] = arr[5];
arr[5] = arr[0];
Explanation / Answer
Option C is correct.
int k = arr[0];
arr[0] = arr[5];
