logic of c program to find square root of a number without using sqrt(x) function

• #include
  #include
  float sqroot( float x){
  float a , b;
  a = x; // copy given value to 'a'
  do{
  b = a;
  a = (a + x/a)/ 2; //This equation is from Newton-Repson Method
  }
  while( a!= b); // execute loop until a == b
  return(a); // 'a ' or 'b' is sqroot of 'x'
  }
  
  main(){
  float x;
  printf("Enter any number n");
  scanf("%f", &x);
  
  if( x > 0)
  printf(" SQRT(%f) = %fn", sqroot( x));
  else
  if(x < 0)
  printf(" SQRT(%f) = %fi n", sqroot( -x));
  else
  printf(" square root is 0 n");
  getch();
  }
