Hi again, I managed to find a big problem in my code -- I didn't increment the variable of the condition of the while loop so in essence I had an infinite loop going without knowing I had created it.
But I am still getting output that I am not sure if it is correct ?
This is the output that I am getting :-
Enter number iterations for Pi value: 5
The value you entered was: 5
The value for valuesofar is: 1.0
the value for x is: 3
The value you entered was: 5
The value for valuesofar is: 1.0
the value for x is: 5
The value you entered was: 5
The value for valuesofar is: 1.0
the value for x is: 7
The value you entered was: 5
The value for valuesofar is: 1.0
the value for x is: 9
The value you entered was: 5
The value for valuesofar is: 1.0
the value for x is: 11
The value so far is: 1.0
And I doubt whether 1.0 is the answer that I am supposed to be getting ?
----------------------------------------------------------------------------

The question that I am getting is as follows :-
Approximating the value of pi :-
pi/4 = 1 - 1/3 + 1/5 - 1/7 + ........
Write a program that allows the user to specify the number of iterations
used in this approximation and displays the resulting value ?
My code is as follows and also will be included as an attachment :-

import TerminalIO.*;
public class Liebniz {
KeyboardReader reader = new KeyboardReader();
ScreenWriter writer = new ScreenWriter();
int i;
int x;
int numiter;
double valuesofar;
//================================================================
public void run() {
numiter = reader.readInt("Enter number iterations for Pi value: ");
i = 1;
x = 1;
valuesofar = 0;
while (i <= numiter) {
writer.println("The value you entered was: " + numiter);
if ((i % 2) == 0) { valuesofar -= 1 / x;
} else {
valuesofar += 1 / x;
}
writer.println("The value for valuesofar is: " + valuesofar);
x = x + 2;
writer.println("the value for x is: " + x);
i++;
}
writer.println("The value so far is: " + valuesofar);
}
//=================================================================
public static void main(String [] args) {
Liebniz tpo = new Liebniz();
tpo.run();
}
}
