2 سوال ساده- براکت و جذر

براکت (جزء صحیح)(کف):

#include <iostream>
#include <conio.h>
using namespace std;
main()
{
  double num;
int b;

cout << "input  number:";
cin >> num;
b = num;
cout << "["<<num<<"]= ";
if ( num - b < 0)
    cout << b - 1;
else
cout << b;
getch();
}

جذر:

#include <iostream>
#include <conio.h>
using namespace std;
main()
{ double x = 1 , num;

cout<<" number:";

cin >> num;

for (int i = 0; i < 20 ; i++)

x = ( x + ( num /x ) ) / 2;

cout<<"\/---- "<<num<<" = "<<x;



	getch();
}
