Answer / vinayak bhat

a=10*10
It s a macro concept,,very simple
a=a*a becomes
a=10+10*10+10
* has highest priority than +
hence expression becomes like
a=10+(10*10)+10
a=10+100+10
a=120

Answer / nagarajanselvaraj

In C everything is case sensitive
so variable with name 'a' differs from variable
with name 'A'
The given result is not possible
because 120 is not a square number.

main( ) { static int a[ ] = {0,1,2,3,4}; int *p[ ] = {a,a+1,a+2,a+3,a+4}; int **ptr = p; ptr++; printf(“\n %d %d %d”, ptr-p, *ptr-a, **ptr); *ptr++; printf(“\n %d %d %d”, ptr-p, *ptr-a, **ptr); *++ptr; printf(“\n %d %d %d”, ptr-p, *ptr-a, **ptr); ++*ptr; printf(“\n %d %d %d”, ptr-p, *ptr-a, **ptr); }
