  @Pushkar: dont use getch(), getch() is not included in standard c++ library.
  Instead maintain structure like this.
  

  #include
  #include
  int  main(int argc,char* argv[])
   {
   //....codehere.....
   system("PAUSE");
   return 0;
   }

  #include
  #include
  main()
  {
  float area;
  int radius=1;
  area=circle(radius);
  printf("%f",area);
  }
  circle(int r)
  {
  float a;
  a=3.14*r*r;
  system("PAUSE");
  return(a);
  
  }

  i wrote this program, the output window was appeared but when i pressed any key to continue, the output window get disappeared 😔

  Well Pushkar in my opinion you need to put system("PAUSE") just before the closing braces of main function .Try this code:
  
  

  #include
  #include 
  circle(int r);
  main()
  {
  float area;
  int radius=1;
  area=circle(radius);
  printf("%f\n",area);
  system("PAUSE");
  return 0;
  }
  circle(int r)
  {
  float a;
  a=3.14*r*r;
  
  return(a);
  
  }
