Answer 1

10+2=12

int a[] = {0,1,-1,10,11} ;
int *p = a ;

initially p points to first location of array a by
int p = a; that is *p = 0
next p = p+3 cause pointer to forward 4th (index 3) element and *p = 10.

so *p+2 returns => 10+2 = 12

Answer 2

G'day Abhay mishra nice code.
Would you like a few pointer challenges?

What about using a pointer to access a 2d char array, maybe days of the week?

I still do that the long way: {my psuedocode}

Create array
Make a loop
Use loop counter to multiply the pointer return, eg *(p+ i*arr2dSize)
