Tell me please ...whats wrong with this program?

Question

import java.util.*;
class sum
{
public static void main(String[] args)
{
float x,n,s=0,i,g,h;
Scanner in= new Scanner(System.in);
System.out.println("enter value of x and term of the series");
x=in.nextFloat();
n=in.nextFloat();
g=math.pow(x,i);
h=math.sqrt(i);
for(i=1;i<=n;i++)
{
s=s+ g/h;
}
System.out.println("sum series="+s);
}
}

Answer 1

//I have listed all errors , U must have followed mine comment carefully ,
//btw here is the corrected code

import java.util.*;
class sum
{
public static void main(String[] args)
{
float x,n,s=0,i=2,g,h;
Scanner in= new Scanner(System.in);
System.out.println("enter value of x and term of the series");
x=in.nextFloat();
n=in.nextFloat();
g=(float)Math.pow(x,i);
h=(float)Math.sqrt(i);
for(i=1;i<=n;i++)
{
s=s+ g/h;
}
System.out.println("sum series="+s);
}
}

Answer 2

if u don't initialize i , then how the compiler will know that what power should x be raised ... and that value to be stored in variable g

Answer 3

1)System.out.print
2)Math.pow
3)Math.sqrt
4)Math.pow & Math.sqrt returns a double value , so there will be loss of precision when assigned to float type , its better to use typecasting
5)In Math.pow(x,i)
//here i is not initialized

//only these errors comed to my notice 😅

Answer 4

Variable i is not initialized

Answer 5

we don't initialize 'i'... m talking about your 5th point

Answer 6

and what's wrong...I'm not getting required output

Answer 7

Thanks...the way I have written g&h ...there it's shows a error...even after intializing 'i' ... what's wrong there....
