In this program we will going to find the square root of the given number without a square-root function.

C Program to find the square root of the given number without a square-root function

#include <stdio.h>
#include <conio.h>
int main()
{
  int num;
  float sqrt, s;
  printf(" Enter a number to get the square root: ");
  scanf(" %d", &num);
  sqrt = num / 2;
  s = 0;
  while (sqrt != s)
  {
    s = sqrt;
    sqrt = (num / s + s) / 2;
  }
  printf(" \n The square root of %d is %f", num, sqrt);
  return 0;
}
