All are wrong. 2,2,32 is correct answer

3,2,32 is correct ans.

ans is here

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.

3,2,32 is not mention

Question 6

Time: 00:00:00
What will be output of the following program where c=65474 and int=2 bytes. int main() {  int c[3][4]={2,3,1,6,4,1,6,2,2,7,1,10};        printf(“%u, %u\n”, c+1, &c+1);        return 0; }

65482, 65498

65482, 65498

65476, 65476

65476, 65476

65476, 65498

65476, 65498

Here c[3][4]= { {2,3,1,6}; {4,1,6,2}; {2,7,1,10} }; c+1 means c is base address i.e. address of 1st one Dimensional array and on incrementing it by 1 means it points to 2nd one 2 Dimensional array. So, c+1=65474 + ( 4 * 2)= 65482 But, when we are writing &c, that means address of this whole array i.e. address of next new array. So, &c+1=65474 + (12 * 2)=65498

wrong output
