See the program

Answer 1

This is 1 of my fav. C++ quiz...
here m++ increments the index value of array m by 1 each time...
so m[i] = m[i] * 2 is applied to the index values 0,2,4 and rest r left as it is i.e. index values 1 & 3..
so output is 21212
i hope this helps... ✌️👍😎
m++ is very imp. factor here...
just change it to m+=2
o/p will. become 21121

Answer 2

m++ = m+1

Answer 3

My argument is see the program here m is taken as an array a[5] = {1,1,1,1,1}
so a = m right
so how can I increase the value of an array?
