error in loop with if statement, but gets compiled and terminates without error without displaying expected result

While solving the question(It is in the code as comment.) The if statement (which displays the result) is not working. Please help me to figure out the error. It gets compiled and runs but output is not displaying.

/*
 * (Calculating the Value of π ) Calculate the value of π from the infinite series
         4     4     4     4      4
π = 4 – --- + --- – --- + --- – ------ + ...
