I've been trying to make first example program work for about an hour now and I've re-typed it multiple times but it still gives me the same error
ExampleProgram.java:3: error: cannot find symbol
System.out.printIn("Hello World");
And the arrow is pointing at the period (.) after out. Anyone can help me?

9 odpowiedziI'm trying to calculate the decimal places of pi with Ramanujan's formula. but with this code I'm getting the same output for all values of n, which it shouldn't.
from math import sqrt, factorial as f
sum=0
n=0
k=(2*sqrt(2)/9801)
while n<=100000:
sum=sum+((f(4*n))*(1103+(26390*n)))/(((f(n))**4)*(396**(4*n)))
y=1/(k*sum)
print('%.60f' % y)
n=n+1
where am I doing wrong?

4 odpowiedzihey guys, I've been trying to work out the formula 'v=I*r'. But whenever I run the program and input values for I and r, it doesn't give the right answer.
This is the code
#include <iostream>
using namespace std;
int main() {
int i,r;
int v = i*r;
cout<<"what is the value of i?\n";
cin>>i;
cout<<"what is the value of r?\n";
cin>>r;
cout<<"voltage ="<<v<<endl;
return 0;
}
p/s: I'm new to programming

4 odpowiedziSo I'm trying to add a picture to my website atm and I'm new to this so I got this app. The image is a .pgn and even if I say <img src="thename.png" /> it doesn't work on the site. I've updated it from Filezilla obviously but it just shows a little jpg logo and doesn't display my pic. What am I doing wrong?
