Here, ++b[1] means that firstly b[1] will be incremented so, b[1]=2 then assigned to k i.e. k=2. b[1]++ means firstly b[1] will be assigned to variable l i.e. l=2, Then value stored in b[1] will be incremented i.e. b[1]=3. b[k++] means first b[k] will be assigned to m i.e. m=32, then value of k will be incremented i.e. k=3.

Explaination: firstly right side of any expression is evaluated, then the left side is evaluated. So, here ++i will be evaluated at first, then a[i]. Hence, when i=0, a[1]=1, then i=1, a[2]=2,…a[4]=4 and a[0]=garbage value
