first C++ programm..

Hi i have just started with C++ and did this small app...just wanted u guys to take a look at it and give me some point .And one more thing instead always typing using std:: etc etc...isnt there another way ..thanks

Code:

---


#include <iostream>
#include <cstdlib>
#include <cstdio>

using std::cout;
using std::endl;

class Rectangle{
      public:
            Rectangle();
            int perimeter();
            int area();
            // set functions
            void setlenght(int);
            void setwidth(int);
            // get functions
            int getlenght();
            int getwidth();
            //draw function
            void drawRec();
      private:
              int lenght;
              int width;
};

Rectangle::Rectangle(){ lenght = width = 1; }

void Rectangle::setlenght( int l ){ lenght = ( l > 0 ) ? l : 0; }
void Rectangle::setwidth( int w ){ width = ( w > 20 ) ? 20 : w; }

int Rectangle::getlenght(){ return lenght; }
int Rectangle::getwidth(){ return  width; }

int Rectangle::area(){ return (lenght*width); }
int Rectangle::perimeter(){ return 0; }

void Rectangle::drawRec()
{
    int array[25][25]={0} ;

    array[0][0] = 201;
    array[0][lenght-1] = 187;
    for ( int cnt_main = 1; cnt_main <= lenght-2; cnt_main++ )
        array[0][cnt_main] = 205;


    array[width-3][0] = 200;
    for ( int cnt_main = 1; cnt_main <= width-4; cnt_main++ )
        array[cnt_main][0]= 186;


    array[width-3][lenght-1] = 188;
    for ( int cnt_main = 1; cnt_main <= lenght-2; cnt_main++ )
        array[(width-3)][cnt_main] = 205;

    for ( int cnt_main = 1; cnt_main <= width-4; cnt_main++ )
        array[cnt_main][(lenght-1)] = 186;

    cout << "\n\n";

    for ( int cnt_main = 0; cnt_main <= width-1; cnt_main++, cout << "\n" ){
        for ( int cnt_sub = 0; cnt_sub <= lenght-1; cnt_sub++ ){
            if(array[cnt_main][cnt_sub] == 201)
                putchar(201);
            else if ( array[cnt_main][cnt_sub] == 187 )
                putchar(187);
            else if ( array[cnt_main][cnt_sub] == 205 )
                putchar(205);
            else if ( array[cnt_main][cnt_sub] == 200 )
                putchar(200);
            else if ( array[cnt_main][cnt_sub] == 186 )
                putchar(186);
            else if ( array[cnt_main][cnt_sub] == 188 )
                putchar(188);
            else
                cout << " ";
        }
  }

}



int main(void)
{
  Rectangle t;
  int len, wid;


  cout << "Enter you length and width: ";
  cin >> len >> wid;

  t.setlenght(len);
  t.setwidth(wid);

  cout << "\nThe Area of rect with lenght "<< t.getlenght() << " and width is "
        << t.getwidth() << " is " << t.area() << endl;

  t.drawRec();


      system("PAUSE");
      return 0;
}

as for the std:: stuff, you could do, "using namespace std;", without the quotes

Hey thanks alot man .I needed that ..;)

You spelt length wrong, but other than that you code looked good.
