Command Line Program to Calculate the Square root of a function

Write a C program which will calculate the square root of a number without using math.h sqrt() function and print that sqrt to the STDOUT as floating point number with exactly 2 decimal precision.

[code language=”cpp”] 
#include<stdio.h>
#include<stdlib.h>
int main(int argc, char *argv[])
{
if(argc==1)
{
printf("No arguments");
return 0;
}
else
{
int n;
n=atoi(argv[1]);
float i=0.00;
while(i*i<=n)
{
i=i+0.001;
}
i=i-0.001;
printf("%.2f",i);
}
}
