C code for finding square root of a number without using sqrt() function.

 The code has the following features

•     This following code finds a square root for a given number.
•     You can also find square root for a floating number.
•     This code is using a Mathematical formula.

Here is the code

  float squareRoot(float n)
  {  float prev=0,cur=1;
     while(prev!=cur)
      {   prev=cur;
          cur=0.5*(prev+(n/prev));
       }
     return cur;
  }                         //Try this code..It works great..
