   1:  #include<stdio.h>

   2:  #include<conio.h>

   3:  #include<math.h>

   4:  void main()

   5:  {

   6:  float x,s;

   7:  clrscr();

   8:  printf("Enter the real num:");

   9:  scanf("%f",&x);

  10:  if(x>0.0)

  11:  {

  12:  s=sqrt(x);

  13:  printf("Square root of x is: %f",s);

  14:  }

  15:  getch();

  16:  }
