57Consider the following snippet of a C program. Assume that swap (&x, &y) exchanges the contents of x and y.

{
int array[]={3,5,1,4,6,2};
int done =0;
int i;
while (done = = 0)
{
done = 1;
for (i = 0; i <=4; i ++)
{
if (array [i] < array [i +1])
{
swap (& array [i], &array [i+1]);
done = 0;
}
}
for(i = 5; i > =1; i --)
{
if (array [i] > array [ i-1])
{
swap (& array [i], &array [i-1]);
done = 0;
}
}
}
printf (“%d “, array [3]);
}
The output of the program is _____.

Option : A
Explanation :
For the first time the first for loop will be executed completely, the content of array will be as follows :
5,3,4,6,2,1
After the second for executed completely the content of array will be as follows:
6,5,4,3,2,1
Array[3] = 3 so ans is 3 Because of the array will start from zero address .
