Pls explain me this code..

#include <iostream> using namespace std; int main() { int c,j=0,n=0; for (c=1;c<=5;c++) { j=j++; } n=j+2; j=n; cout<<j; return 0; }

I was confused. But then I realize it's j++ not ++j

Everytime j=j++ gives the same value to j it means j=0 in every loop . After loop it is added by 2. Thus u get j=2. This is one quiz question.

Good question. Now,here if we could use the keyword "static" to declare j, then may be, as per definition, it would update "j" everytime the for loop revolve.
