For anyone watching this, make sure that in your if statements that you use == to compare. if (j = 0) is setting j to 0, not checking if it is 0 if (j == 0) checks if j's value is 0.

[@versache8247]

I know I'm 11 months late and that this might be a dumb question, but why do people prefer writing "++j" instead of "j++" in a For? j++ seems more natural to me, is anything different if you write it the other way around?

[@ishant0wn]

if you write "++j" it will add 1 to j before it counts the value of j and if you write "j++" it will count the value of j then add 1 to it. In for loop it doesnt make that big of a diffrence (i think). So if you write this: int a = 0, b = 0; cout

[@denzellupheng7063]

Whats the difference between system(“cls”) and clrscr() ?

[@user-bo5vr1ib6i]

From what I could find from a quick search, clrscr() is an old function that is only included with a header file that comes with some old C compiler. Whereas system() is a C/C++ Standard function, meaning it has to be included in every compiler, and "cls" is just the console command to clear the screen. Apart from that, I think the functions are identical with that as an argument to system().
