I created this program will the help of some of my friends and now I need to
analysis it. Would someone please tell me how all of these for loops work.
How can I explain the output and  how the output is determined?

#include <iostream.h>

#include <conio.h>

#include <iomanip.h>

int main()

{

clrscr();

// for loop 1

for (int x =0; x <10 ; x++)

cout <<setw(3) << x;

cout << endl;

// for loop 2

for (int y = 1; y <= 10; y += 2)

cout << setw(3) << y;

cout << endl;

// for loop 3

for (int z =10; z > 0; z --)

cout << setw (3) << z;

cout << endl;

// for loop 4

for (int a =10; a < 0; a++)

cout << setw(3) << a;

cout << endl;

getch();

return 0;

}
