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.

code of a program in c language that ask a number and print its decremented and incremented number.. sample output: input number : 3 321123
